Should have been easy

Late Thursday night during a thunderstorm, I played a few three minute games online. Two draws from dead lost positions became lessons in elementary endings to end the spring term for my before school elementary chess club.

In the first, my opponent ran desperately short of time in a bishop ending where he had an significant advantage in number of pawns. After promoting a pawn and using the queen to capture my last pawn, he had a forced checkmate in seven, but only 4.0 seconds left.

Black to move
50...Qe4+

My opponent opts for a sequence where premoves can be played to save time.

50...Qc7 leads to mate in six moves more.

51.Kd6 f4 52.Kc5 f3 53.Kd6 f2 54.Kc5 f1Q

A second queen appears and 3.0 seconds remain on the clock. It is also forced mate in three. Black has done well and should win.

There are two schools of thought on this position:
1) a decent player resigns in such a hopeless position, and
2) its is foolish to resign in a blitz game when your opponent has three seconds left.

55.Kd6

Black to move
What should a player know about checkmate with two queens?

From the hardest position against a lone king, it is mate in four. Checkmate can occur in the middle of the board. Checks are often the best move.

Most players, however, seem to think the ladder mate is simplest and therefore best. In this case, it can be accomplished with premoves.

55...Qff5

This move does not get closer to checkmate. That is, mate is still three moves in the future.

55...Qf6+ executes an easy ladder mate unless White opts for 56.Kc5 Qfc6#
I would probably play 55...Qa6 in a heartbeat.

56.Kc7 Qee6 57.Kd8

Black still has 2.8 seconds remaining and a simple mate in one.

57...Qff7??

The premove squandered half a point.

The second undeserved draw had gross errors by both players. Time was a less critical factor with both having more than half a minute on the clock.

White to move
58.Rh6??

I would play 58.Rb6

One of very few non-winning moves in this simple rook ending.

58...Rh1+ 59.Kg4 Rg1??

Black here is stuck in unimaginative routine moves that were wholly unnecessary when simply calculation shows that 59...Rxh6 draws easily.

60.Kf4 Rf1+

White to move
I started with this position with the young students, explaining that moving the king towards the rook puts an end to harassing checks. Ke4-d3-e2 (or f6+ if the rook gives up the checks).

61.Ke5 Re1+ 62.Kf4 Rf1+ 63.Kg4 Rg1+

At this point the game is technically drawn, as a repetition is about to occur. It is sad that a player rated in the mid-1900s does not know how to win this ending.

64.Kh5 Rh1+ 65.Kg4 Rg1+ drawn by repetition.

Binges

Chess is a drug. Joseph Blackburne called it, "mental alcohol". In moderation, the game can enrich a balanced life. A well-played game offers pleasure not only during and immediately after play, but often for many years.


For long-term pleasure, for example, there is my fifth round game that led to second place in the 2012 Collyer Memorial. I was playing not to lose. My opponent took the game down a path where a draw was extremely unlikely. We both thought I was worse, but I soldiered on, playing strong moves to keep myself in the fight. Then, after spending substantial time calculating some endgame possibilities, I discovered that I had the better game (see “Pawn Wars”). This ending has become a staple in my teaching and still challenges me while examining a testing alternative that my opponent could have played. Had he played that move, my necessary response to maintain the advantage tests my calculation skills. A single error shifts the advantage to my opponent. Such is the pleasure of the game.

On the other hand, chess can become an obsession where winning is all that matters. To be pulled from the game may cause anxiety, attention impairment, headache, high blood pressure, insomnia, and other symptoms. Losing also provokes some of these symptoms. For instance, while writing this post, I had a morning where I managed to outplay an opponent 200 points higher rated, only to drop my rook unprovoked in a rook vs. bishop endgame. The likely win became a sudden loss. The very next game, I was a pawn down, but my rooks and queen were more active. Then I gave away my queen for nothing. My fury with myself suggested an elevation in blood pressure.

A chess playing binge followed and after more substandard play, I began to focus better and won a sequence of games. There was not much pleasure in the wins, but it was easier to stop playing.

Binges usually leave me tired, but so does tournament chess. Binges in search of redemption after poor play leaves me in a sour mood. My wife notices because I’m less fun to be near. Tournament chess leaves me with memories to cherish and games worthy of study.

Losing sometimes motivates me to play better, as it should. But losing can fuel obsession, and then substituting quantity for quality becomes a danger. When the play becomes a long session of just playing for wins, rather than enjoying the struggle, chess lacks the pleasure that is gained from solving problems against a difficult and talented opponent. One Friday, I was tired due to responsibilities in the first week with a new puppy. In such a state, I was playing chess online with little pleasure and much frustration. I was not well focused. It was the Friday before the Spokane Chess Club’s premier event. IM John Donaldson gave a lecture and simul that evening. I had pulled myself away from an online binge in a sour mood, but my disposition improved once I was among chess playing friends for Donaldson’s event.

During the weekend, I played in the tournament. Losing my first-round game to a much lower rated talented junior was not disheartening, even though it meant weaker opponents for the duration of the weekend and certain rating loss. The play, analysis, and camaraderie of a chess tournament lifts the spirits. My longest game was in the last round against an opponent from Tacoma. It was a battle. My play was far from perfect, but I enjoyed the struggle. Such contests are at the heart of chess’s appeal. Winning was quite satisfying, especially because of challenges my opponent threw in my way. The game lasted more than three hours and I spent another five or six analyzing the game in subsequent days.

Sometimes a string of losses is nothing but pain and obsession, especially when the first loss made clear that I am not prepared to play. For instance, I lost five of six games one night recently because I was playing late at night when I was too tired to continue my reading of Theodore Roosevelt, The Rough Riders (1899). Moreover, I had consumed two or three glasses of Scotch. One glass never has a detrimental effect on my play. A second glass can go either way. The third should not be consumed prior to or during a chess playing session. If I recall correctly, that third glass came after some losses and after my wife retired for the evening. As the clock moved toward midnight, I was drinking Scotch without tasting it and playing chess without enjoyment.

It is better to practice moderation in chess, in drinking, and in combining the two.

Most often, my chess playing binges are in the middle of the day. I am awake, alert, and sober. Perhaps sobriety is open to question, however, because the behavior of playing one game after another without reflection is reminiscent of the way I drank beer in college, one after another until I could take no more. Then, quantity was the means to a goal: inebriation. I don’t live that way now.

The worst part of chess binges are my attitude. I regret the waste of time. I could have gone for a walk, done some chores, or read a book. I have unfinished writing projects that interest me. Frustration with my lack of self-control can lead to depression. Rating loss can provoke repetition of the behavior.

After a quarter century of online chess play, I’m coming to terms with binges as an element of my life. I am okay. Binges happen. Going forward, I will accept these moments of obsession as a by-product of my love for chess. 

When my chess obsession interferes with other aspects of life, it becomes a problem. Jenna Ostria has some useful tips for curbing this obsession. My health is my top priority. While accepting myself even when I binge, I also work to keep chess in balance with other areas of life. Each day I make time for chess, household responsibilities, and reading. My new puppy also demands attention! She also brings joy.

The Strongest Move

After having written two articles on the subject last spring, I should have found the strongest move here, even though it was a blitz game.

White to move
I did find the best move here, however.

White to move
Had this next position appeared in the game, I likely would have missed the strongest response, playing instead another move that also wins, but in more moves.

White to move
It mystifies me that I again missed the best move here below because it had been my intent a move earlier. As a consequence, my advantage began to slip away.

White to move
But, my opponent missed the critical reply.

Black to move
This next move was easy to find.

White to move

Instinct

Blitz offers little time for calculation. One must see patterns or play by instinct. Naturally, many players work on having openings that trip up their opponents for a quick win. But games often last into the endgame, too.

I had this position this morning.

White to move

With a 3-2 pawn majority on the queenside, of course I want to exchange rooks.

Stripes,J. -- Internet Opponent [C40]
Live Chess Chess.com, 23.06.2021

34.Rxg7+ Kxg7

Both players are under a minute. White 58 seconds; Black 55 seconds.

35.Kg1 Kf6 36.Kf2 Ke5 37.Ke3 Kd5 38.Kd3

Coincidentally, I was able to maintain the opposition as the kings moved towards the center. Or, was that something I noticed before the rook exchange?

Black to move

38...c6

38...h4 also would be met with 39.a4.

39.a4 a6

White to move

40.g3

Best

40...g4 41.h4

Black is in zugzwang. The king must give way to allow White's plans to convert his majority into a passed pawn. And that results in a pawn race of sorts, and then queen against pawns.

41...Ke5 42.Kc4 Ke4 43.b5 axb5+ 44.axb5 cxb5+ 45.Kxb5 Kf3 46.c6 Kxg3 47.c7 Kxh4 48.c8Q Kh3

White to move

Instinct tells me to move my king closer. How would I have such instinct? I've studied positions in many endgame books, have taught these positions to my students, and have played them against computers and against human opponents.

49.Kc4

Tablebases say that it is mate in nine and this is the only move to make it mate in eight.

49...h4

49...Kh4 50.Kd3 g3 51.Ke2 g2 52.Kf2

50.Kd3

50.Kd4 was equally good.

50...Kg3 51.Ke3

51.Qf4 was as good.

51...h3

White to move

52.Qc7+

When the standard is perfection, as it should be, this move must be accounted an error. I missed a mate in five.

52.Qc2 h2 53.Qf2+ Kh3 54.Kf4 h1N 55.Qg1 Nf2 56.Qg3#

52...Kg2 53.Qc6+

And again, 53.Qc2+ or 53.Qf4 g3 54.Ke2 Kh1

53...Kh2 54.Qd6+

Still missing the fastest checkmate.

54.Qc2+ Kg1 55.Qf2+ Kh1 56.Kf4 g3 57.Kxg3 h2 58.Qf1#

54...g3 55.Qf4 

Black to move

55...Kg2

55...Kh1 is more stubborn. 56.Qxg3 h2 57.Qf3+ Kg1 58.Qf2+ Kh1 59.Qf1#

56.Ke2 h2

Still 56...Kh1 holds out a few moves longer. 57.Qxg3 h2 58.Qf3+ Kg1 59.Qf2+ Kh1 60.Qf1#

57.Qf1# 1-0

The endgame was easy, but felt rushed even though I had almost half a minute left when it ended. Three minute chess is always frantic.

Playing Online (Pros and Cons)

The first time that I played chess via the internet was 1989 when my younger brother let me play in his place some regularly scheduled telnet games with a friend of his in another city. Both my brother and his friend were programmers. The Internet Chess Club (ICC) came into existence a few years later. I recall my brother claiming that he helped with some of the programming.

When ICC started charging a membership fee, Free Internet Chess Server (FICS) was created to maintain a free playing environment. After that one evening in 1989, the next time I played online was a now defunct site called Net-Chess in 1998. I joined ICC in 1999 and started playing regularly--maybe almost every day. I also started watching live broadcasts of Grandmaster events.

ICC, FICS, Net-Chess, and Playchess (where I started in 2003) are servers that require software on your computer and send small amounts of data over the internet. Website hosted chess, to my knowledge, began with Yahoo! It was terrible. Chess.com, which came online in 2007 and added live chess after a few months, began to change the quality of website chess. The distinctions summarized in Edward Collins' Yahoo! Chess vs. The Chess Servers are no longer valid.

LiChess, Chess.com, Chess24, and others now have hundreds of thousands of games every day. They also host Grandmaster events and other tournaments, as well as organizing their own. ICC and Playchess also seem to be doing well. It has been several months since I have played on FICS, and many years since I enjoyed the experience. The lag there is terrible, and I lack confidence that they effectively root out cheats.

Last night I played in the World Open Game 7 Championship on ICC. It is organized by the Continental Chess Association. The time control was 7+2. I was very low in the pairing chart in the open section. In seven rounds, I managed one win and two draws. I beat the only opponent who was lower rated (according to USCF standard OTB rating, which was used for pairings). I had chances in several of the games that I lost.

I threw away a clear win from this position, although my opponent had done the same earlier in the game. It ended as a draw one move before we had lone kings.

Black to move

In the next game, I again threw away a clear advantage. This time, I went on to lose.

White to move

My previous post here highlights how these types of errors are often the product of haste.

Next weekend, I am playing in the World Open. The time control is 60 + 10, longer than any time control I have experienced in live online play (I have played hundreds of online correspondence games). This morning, I tried two games at 30 + 10. Both opponents were relatively weak and I won easily. Even so, I was happy that in 46 moves, I made no blunders (according to the website's Stockfish 11), and only three inaccuracies. Two of these inaccuracies were opening choices that I might make again. The other missed a vulnerability that could have been attacked.

One of our strongest local players offers a summary of the pros and cons of online play at his chess tutoring site: Casey Chess Tutoring. I also recommend him as a teacher if you are looking for some instruction.

Rather than creating my own list of the pros and cons, or repeating his, I want to address one point: cheating.

How common is cheating online?

A high percentage of my online correspondence opponents have been banned from the website where we played because of cheating; perhaps 8-10%. In live play, cheating is less frequent, percentage-wise. Nonetheless, like many others, I am usually suspicious when I get outplayed. I often report my opponents, and often check the engine analysis before or after such reporting. Most players are clean. Nonetheless, it happens. During last night's preliminary remarks by an organizer, he stated that they go over every game before an event is rated, and that they usually (he may have said, "always") find cases of cheating.

I was on the organizing committee for the Washington State Elementary Chess Tournament, which went online this year. We had detailed procedures for rooting out cheats, and we had some ethical breaches that we needed to address. We also had nearly 1200 participants! The number of suspicious players was in the dozens, and most were determined to be clean. More than 99% of the participants never faced a suspicious opponent.

A few weeks ago, I ran into a suspicious player in an online tournament. That player's computer match rate in the event was 97%. To be fair, however, all of these games were relatively short. I submitted a cheating report. Later, I learned that my opponent is an underrated and very young youth player. The cheating accusation was likely quickly dismissed by the website. The player is clean. The third time we played, I won.

Cheating also occurs OTB. Is is less common? We need to consider the percentages. The number of games that are played online is astronomically large and the number of cheats relatively small (even if it happens every single day). I do not know whether anyone has compiled clear data on the question. Hence we are left with impressions and anecdotes.

My anecdote is this: I have lost to cheats online. I also have won against them. I have played more than 150,000 live games online. More than 150,000 of these games have been 100% clean. The risk of facing a cheat is much lower than the fears associated with it.

Do not let fear of online cheating stand in the way of playing chess during a time of social isolation. Do consider playing in tournaments, even tournaments that have entry fees and cash prizes. In my experience, the quality of play in online tournaments is worth it.

Slow Down

Over the past twenty years, I have played at least 100,000 games, most at three minutes with no increment (3 + 0). Adding games at five minutes, or with an increment, and adding bullet, which includes a great many 2 + 1 (more time than three minute when the game exceeds sixty moves), pushes the number over 150,000.

These crude minimums belie the point that I do not know the total number of online blitz games I've played. I have played online blitz regularly since 1998, often dozens of games in a day. I play a few games most days. My personal database currently holds 103,382 games. It excludes most bullet games, although I make an exception for 2 +1. It also has many games at longer time controls, including many hundreds of correspondence games. I have not been able to save every game, and have also lost tens of thousands through database errors.

When I started saving my games in a database, I was using Chessmaster 7000. About 2001, I began learning the free versions of ChessBase and Chess Assistant, both limited to database not exceeding 15,000 games. I recall that CB was more restricted than CA. In 2003, I bought CB 8 and attempted to gather all of my online games into one database.

What has been the impact of this massive amount of online blitz on the quality of my play?

The database contains a near endless supply of instructive positions that arise from sloppy play. Exactly the sort of play that my students see in their games.

It has certainly given me ample practice with pattern recognition, and may have developed my intuitive feel for many types of positions. It has given me immense experience in playing my favored openings, such that it is very difficult for an opponent to surprise me with something that I have not seen before.

Performing elementary checkmates with minimal time on the clock is gratifying, and helps me reinforce the skill in my teaching. But, it is also humbling that I have stalemated my opponent with queen and king against king more than once.

The most important detrimental impact has been that unsound risky play has been rewarded in such a way that it has become second nature. Making the effort to switch to 3 + 2, or even the 5 + 2 that I am currently playing in USCF online blitz rated tournaments has been rough. It is much more difficult to win lost positions on the clock when there is an increment. In my OTB games, I have bouts of impatience where blitz thinking interferes with careful calculation.

Last week, I had White and this position.

White to move

Confidently assuming that I had a strategic advantage, I was blind to tactics. I had plenty of time, but did not use it.

22.Bg2?? Rxd2 and I resigned.

The Morning Membership tournaments are short and fun, and they are at a time that is good for me both in terms of schedule and capabilities. Unlike the stereotypical late-night chess player, I am a morning person. These events last about an hour, are played at 5 + 2 on Chess.com, and draw 30-40 players. They begin at 8:00 am in my west coast time zone, which is late morning on the east coast.

In my first event on July 8, I was the third highest rated player, tied with two others with perfect scores, and won the first place trophy on tiebreaks. The free membership extensions that are awarded after the event are based on a random drawing, not performance. I played three more this week. The blunder presented above was my first loss. I scored 2/4 on Monday, lost my last round game on Wednesday, and on Friday, when I was the top rated player, gave up a draw in the second round.

My online blitz rating is going down. Nonetheless, I have signed up for the next sixteen--every one through the end of August. Learning to pace myself in slower blitz may be good for my game.

In "The Soul of Philidor", I presented a position where I was happy with my choice because it reflected the application of recent study. Strategically, it was a nice game and I was happy with my performance. Postgame analysis, however, quickly revealed to me that I missed several opportunities. Using the engine to check my postgame analysis revealed more missed opportunities. As I learn to slow down, perhaps I will increase my alertness to tactical chances. Intuitive play has its place, but some calculation is necessary for improving my game.

In each of these five positions, I had a better move than the one I played. Although I dominated most of the game and managed to win, I did concede the advantage and was even worse through part of the game.

White to move

I played 10.a3??

A couple of weeks ago, I was examining the tactics in a Grandmaster game that involved the type of position that occurs after the superior 10.b5!

White to move

15.Nd4?? walked into a fork, although that was not fatal and my pawns proved to be compensation for the knight. But 15.Nxe4 or 15.Bb5 were both better choices

White to move

16.Bg3?? turned out okay in the game, although Black now has a clear advantage. After 16.Nxd5 exf4 17.f3, White has a decisive advantage.

White to move

22.b5 Na4 23.Ra3 Nc2 leads to the next position, and I again have an advantage. However, 22.Re3 wins a piece. I also could have played 21.Re3, but 21.Bf3 was good enough to regain the advantage.

White to move

24.Rxa8! was a move that I considered, but without adequate calculation. Black is busted.

I played the seemingly safer 24.Qb3. A few moves later, my opponent returned the sacrificed piece which left me a clear pawn ahead. My bishops also controlled the squares my passed b-pawn needed.
I can play better.

Smith-Morra Sideline

In my online blitz junk, I often play an extreme version of the Smith-Morra Gambit that takes an idea from the Danish Gambit, offering a second pawn for rapid mobilization. It is unsound. The opening is for blitz only. The regular Smith-Morra, however, can be useful in standard rated over-the-board play and even in correspondence.

Black can decline White's sacrifice in the Smith-Morra Gambit. In a blitz game last night, my opponent did that. The game proved testing for a line that had been mostly successful for me.

Stripes,J. (1997) -- Internet Opponent (2042) [B21]

4.f4!?

My innovation, played 18 times with 14 wins and 4 losses. Although I cannot claim to be the first who has played it.

4.Bxd3 is the normal move.

I have not seen this move often, but in retrospect, it seems the best way to make the argument that White's line of play may be poorly thought out.

8...Bf5 9.Qxd5 Nxd5 10.Nc4 e6 11.Ne3 Bc5

White to move

The engine has the game as equal and both players are making top choices. Nonetheless, White seems to lag in the mobilization of his pieces, which also lack coordination. White's king is also more vulnerable.

White's position is much more difficult to play than Black's. In blitz, that alone can be decisive.

12.Nxd5?!

12.Nxf5 is still roughly equal.

White struggled the whole game to mobilize his pieces without success. Black, meanwhile, was able to consistency apply pressure. White eventually collapsed from the pressure. Despite my nearly 75% scoring percentage with 4.f4, the line cannot be recommended.

Secure the Advantage

In a blitz game late last night, I blundered away my queen and spoiled a nice position. Nonetheless, I went on to win the game. This morning, I struggled to find where my opponent went wrong. The fatal error is not difficult to determine, but what would have secured the win?

Black to move

Blitz Woes

I have blitz binges. As the addict returns to his or her drug to escape life's stresses, I play blitz for hours on end. Losses drive me to play more, but I can sometimes quit after a win.

The past ten days or so, I have been highly motivated.

Premature Resignation?

This position arose in an online blitz game. In such games, some players attempt to appear respectable and resign when slightly worse. Others try to win dead drawn opposite colored bishop endings on the clock. There are many other behaviors in between these extremes.

White to move

White is clearly better. However, White's move 33.Bxh6 is not the knockout that White imagined. Nonetheless, Black resigned.

Play might have continued 33...Qf3+ 34.Qxf3 exf3+ 35.Kxf3 gxh6.

Although White's advantage is clear, it is far less than it was before 33.Bxh6 and in blitz, errors should be expected.

I would play Black's move here in a heartbeat, but it takes longer for me to see the ramifications with clarity. From a blitz game.

Anatomy of a Miniature

Miniatures (games ending in fewer than 25 moves) occur because one of the players makes a catastrophic error. This game was played with each player having three minutes for the whole game. With such a time control, errors abound.

Alekhine-Chatard Attack

In the past, I have struggled against the Alekhine-Chatard Attack, which only seems to get deployed against me in blitz. I have neither faced it over the board, nor in correspondence play. Nor have I spent as much time studying the books than on other variations for White against the French Defense. Consequently, I rely on my instincts and often falter.

Last night, I faced it in a blitz game against a National Master. I won!

1.e4 e6 2.d4 d5 3.Nc3 Nf6 4.Bg5 Be7 5.e5 Nfd7 6.h4

Black to move

Black has many choices here.

Accepting the gambit has been my usual response, but I have tried all or most of the main options. I have lost more than I have won. A year or so ago, while discussing this opening with a friend who has played the French longer than I have and is higher rated, he mentioned that Black can simply castle.

Viktor Moskalenko recommends castling in The Even More Flexible French (2015).

6...0–0 7.Bd3

According to Moskalenko, 7.Qg4 is the "most aggressive option" (339). According to PowerBook 2016, however, 7.Bd3 has a better scoring percentage for White.

7...f5?!

7...c5 is the recommended move.

8.exf6

8.Nh3!

8...Nxf6 9.Nf3

Black to move

9...Nc6!?

I have two prior games from this position. Both are losses.

9...c5 is the only move in PowerBook 2016.

10.0–0

10.Qe2 was played in those two prior games. One ended quickly: 10...Ng4 11.O-O-O Nb4 12.Bxh7+ Kxh7 13.Bxe7 Qxe7 14.Ng5+ Kg8 15.Qh5 and missing 16...Bf5, I was mated two moves later.

10...Bd7 11.Qe2 Nb4

White to move

Perhaps Black has equalized. Both players have several options for the struggle. Having castled kingside, White's thematic pawn storm is less of a threat. My opponent quickly lost his way.

12.Bxf6?! Bxf6 13.Ne5? Nxd3 14.Qxd3 Bxe5 15.dxe5 Qxh4

White to move

With a one pawn advantage and no problems, I went on to win.

Critical Moments

How do you analyze a chess game?

I do several things, but the first step--whether my own game or one played by others--is identifying the critical moments in the game. When did the loser reach a technically lost position?

Today was the last day of my tenth annual youth chess camp. The students spent the week--fifteen hours--solving exercises in a workbook (available on Amazon), playing tournament games, discussing games and parts of games with me and with each other. Throughout the week, I stressed a learning process that extends well beyond the week of camp: work on endgames, then tactics and planning, then openings, then study whole games. When they arrived this morning, I had two positions on the two demo boards. We talked about the endgame first. Then we talked about the middlegame.

Black to move

With two legal moves, Black chose the one that loses.

White to move

White turned an advantage into a lost game by moving the queen to the wrong square.

The whole game with annotations at the critical moments is offered below.

After these two positions, we looked at Fischer -- Stein 1967, which they have in their book. Following that presentation, the students worked in groups studying other great games. Then, they played the last round of their tournament. During the last fifteen minutes, we went through the whole game from which I had extracted the two positions that we began with nearly three hours earlier.

It's Only Blitz

I beat a National Master yesterday afternoon. It has been a couple of months since my last win against a titled player, so I was happy to get this one. It was my last game in a blitz playing session characterized by poor play, but it was a better game. Of course, I made errors, but they were less egregious than in my previous several games.

I spent a little more than an hour playing blitz, and at least that much time analyzing this one game. This game was played in less than six minutes. Did it deserve more than an hour of post-game analysis? My opponent shall remain unnamed because he left a clue on his Chess.com page that suggests he would prefer it that way.

1.d4 Nf6 2.c4 e6 3.Nf3 Bb4+ 4.Nbd2

4.Bd2 is the most popular move. Some years ago, I bought and read partly through The Chess Advantage in Black and White (2004) by Larry Kaufman. Many of the lines that Kaufman recommends do not suit me well, but his basic idea has been an influence. He advocates "second best" moves early in the game when it reduces the amount of theory that one must learn.

I am not certain that 4.Nbd2 is second best, but it is second most popular. 4.Bd2 is played twice as often. 4.Nbd2 has a better scoring percentage for White and a slightly higher Elo performance as well. I had the impression that 4.Bd2 was the choice of top Grandmasters, but a check this morning refuted that. Garry Kasparov has played both moves. Magnus Carlsen has played both, but 4.Nbd2 more recently. Maxime Vachier-Lagrave seems to favor my choice.

I spent some time thinking about the relative merits of the choice that White makes here in the Bogo-Indian Defense. Why is 4.Bd2 more popular?

4...Qe7 5.g3 b6

The databases suggest that this move is rare, but the structure is certainly familiar.

6.Bg2 Bb7 7.0–0 0–0

Castling leads via transposition to a small batch of reference games.

8.Nb3

It is hard to believe that this move has not been played before. There must be something wrong with it. Perhaps, this move offers a clue to the popularity of 4.Bd2. The knight blocks the bishop when it stands there. It also lacks good squares that can be reached from d2. On b3, where I placed it, it interferes with queenside pawn expansion. Other moves seem worse.

Black to move

8...d5 9.a3 Bd6 10.c5!?

This brilliant pawn sacrifice was actually an oversight. I was unaware that I was down a pawn until at the end of the game, savoring my victory, I noticed that material was equal. This sacrifice creates a minor piece imbalance that sometimes favors White, but was it worth a pawn?

10...bxc5 11.dxc5 Bxc5 12.Nxc5 Qxc5 13.Be3 Qd6

13...Qe7

14.Rc1 Na6

14...Nbd7

15.Bf4 Qd7

15...Qe7

16.Ne5 Qe7 17.Nc6

Black to move

At this point of the game, I was pleased with my position. I seem to have my opponent's forces tied down.

17...Qd7 18.Qc2 Rfc8 19.b4 Nb8 20.b5 Bxc6

After this exchange, we have two bishops against two knights and only the c-pawns are blocked.

21.bxc6 Qe7

White to move

How might White squeeze Black from this position?

22.Qb3 with the idea of Qb7 seems to have some merit.

22.Bg5 threatens e4.

I did not spend much time on this position during the game, but invested about fifteen minutes with it on the deck in the evening. It might be one that could be added to the store of middlegame positions for performing Jeremy Silman's inventory of imbalances.

22.e4 dxe4 23.Bxe4 Nxe4 24.Qxe4 a5

Maybe 24...Qxa3

25.Rfd1 Qxa3

Maybe 25...Ra6

26.Bxc7! Na6

26...a4 27.Bxb8 Raxb8 28.c7 looks overwhelming for White.

26...Rxb7 27.Rd8+ Qf8 28.Rxf8+ Kxf8 and the material balance has shifted strongly in favor of White. Even so, a queen and pawn agianst a rook and bishop is not always a winning material advantage in time pressure.

27.Bd6 Nb4 28.c7 h6

White to move

29.Bxb4?

29.Be7! My target is d8. Why not make a move that contributes to this plan?

29... axb4

29...Qxb4 30.Qxa8!

30.Rc6

Black to move

30...b3

30...Qa5 is equal and takes advantage of my error a move earlier.

31.Rcd6 g6 32.Rd8+ Kg7 33.Qe5+ f6 34.R8d7+

34.R1d7+ Qe7 35.Rxe7#

34...Kg8 35.Qxe6+ 1–0

Maybe my pawn sacrifice was sound. Both players committed the sort of positional errors that one might expect in a blitz game.
