Book completed: The Long Goodbye


From Chapter 2 of Raymond Chandler's The Long Goodbye:
It was a quiet night and the house seemed emptier than usual. I set out the chessmen and played a French defense against Steinitz. He beat me in forty-four moves, but I had him sweating a couple of times.
The phone rang at nine-thirty and the voice that spoke was one I had heard before.
"Is this Mr. Philip Marlowe?"
"Yeah. I'm Marlowe."
"This is Sylvia Lennox, Mr. Marlowe. We met very briefly in front of The Dancers one night last month. I heard afterwards that you had been kind enough to see that Terry got home."
"I did that."
"I suppose you know that we are not married any more, but I've been a little worried about him. He gave up the apartment he had in Westwood and nobody seems to know where he is."
"I noticed how worried you were the night we met."
"Look, Mr. Marlowe, I've been married to the man. I'm not very sympathetic to drunks. Perhaps I was a little unfeeling and perhaps I had something rather important to do. You're a private detective and this can be put on a professional basis, if you prefer it."
"It doesn't have to be put on any basis at all, Mrs. Lennox. He's on a bus going to Las Vegas. He has a friend there who will give him a job."
She brightened up very suddenly. "Oh-to Las Vegas? How sentimental of him. That's where we were married."
"I guess he forgot," I said, "or he would have gone somewhere else."
Instead of hanging up on me she laughed. It was a cute little laugh. "Are you always as rude as this to your clients?"
"You're not a client, Mrs. Lennox."
"I might be someday. Who knows? Let's say to your lady friends, then."
"Same answer. The guy was down and out, starving, dirty, without a bean. You could have found him if it had been worth your time. He didn't want anything from you then and he probably doesn't want anything from you now."
"That," she said coolly, "is something you couldn't possibly know anything about. Good night." And she hung up.
She was dead right, of course, and I was dead wrong. But I didn't feel wrong. I just felt sore. If she had called up half an hour earlier I might have been sore enough to beat the hell out of Steinitz-except that he had been dead for fifty years and the chess game was out of a book.
From Chapter 3:
I liked him better drunk, down and out, hungry and beaten and proud. Or did I? Maybe I just liked being top man. His reasons for things were hard to figure. In my business there's a time to ask questions and a time to let your man simmer until he boils over. Every good cop knows that. It's a good deal like chess or boxing: Some people you have to crowd and keep off balance. Some you just box and they will end up beating themselves.
From Chapter 13:
He nodded. He was giving me a careful once over. "Tell me a little about yourself, Mr. Marlowe. That is, if you don't find the request objectionable."
"What sort of thing? I'm a licensed private investigator and have been for quite a while. I'm a lone wolf, unmarried, getting middle-aged, and not rich. I've been in jail more than once and I don't do divorce business. I like liquor and women and chess and a few other things. The cops don't like me too well, but I know a couple I get along with. I'm a native son, born in Santa Rosa, both parents dead, no brothers or sisters, and when I get knocked off in a dark alley sometime, if it happens, as it could to anyone in my business, and to plenty of people in any business or no business at all these days, nobody will feel that the bottom has dropped out of his or her life."
From Chapter 24:
She hung up and I set out the chess board. I filled a pipe, paraded the chessmen and inspected them for French shaves and loose buttons, and played a championship tournament game between Gortchakoff and Meninkin, seventy-two moves to a draw, a prize specimen of the irresistible force meeting the immovable object, a battle without armor, a war without blood, and as elaborate a waste of human intelligence as you could find anywhere outside an advertising agency. 
From Chapter 40:
I put the chessboard on the coffee table and set out a problem called The Sphynx. It is printed on the end papers of a book on chess by Blackburn, the English chess wizard, probably the most dynamic chess player who ever lived, although he wouldn't get to first base in the cold war type of chess they play nowadays. The Sphynx is an eleven-mover and it justifies its name. Chess problems seldom run to more than four or five moves. Beyond that the difficulty of solving them rises in almost geometrical progression. An eleven-mover is sheer unadulterated torture.
Once in a long while when I feel mean enough I set it out and look for a new way to solve it. It's a nice quiet way to go crazy. You don't even scream, but you come awfully close.

Annotated Game #85: Why the Caro-Kann Classical is good vs. lower-rated players

This second-round tournament game helped me bounce back well from the previous defeat (Annotated Game #84) and shows some of the strengths of using the Caro-Kann Classical as an opening weapon.  Despite its well-deserved reputation for solidity, its ideas are complex enough that it offers Black a chance to create imbalances and even get a strong attack going against inaccurate play from White.

When the defense is used against lower-rated opponents, it often occurs that White possesses little knowledge or has few concrete ideas about how to play against it.  Black is unlikely to gain an advantage out of the opening, but if White simply drifts along without a clear plan, Black's counterplay can develop quickly.  This game is an excellent illustration of this, as White allows Black to equalize early on, then never really seems to develop a plan of his own.  The one concrete idea he plays on moves 23-24 simply leads to better play for Black.  By move 31 Black is ready to attack and seven moves later White is mated.

While there were a number of instructive improvements for both sides along the way, the overall development of the game shows how Black can effectively neutralize White's opening play, improve his position, then quickly go over to the attack when an opportunity is given.  This is especially dangerous against lower-rated players who lack the experience or understanding of White's more complex ideas.  Black's position is both simpler to play and has latent attacking resources that the patient player can reveal later in the middlegame.

Annotated Game #84: Piece exchanges and draw offers will lose you the game

This was from the first round of the next tournament following Annotated Game #79.  While the previous tournament had a bad vibe to it from the beginning, this one was considerably better overall.  The fact that I was paired in the first round against a strong Expert player was a big benefit for me, as I didn't feel any pressure to win due to the 500-point ratings gap between us.  My opponent on the other hand did not appear to be as happy and looked even less happy after I had built up a fine-looking position out of the opening, an English - Grunfeld defense setup.

Black makes the first significant error on move 12, unnecessarily moving his rook away from the defense of the f7 square.  I was able to take advantage of this and by playing obvious moves had obtained a clearly superior position as of move 15.  At this point my lack of positional judgment starts to show, however, as I choose the wrong square for the retreat of my knight.  This is followed by allowing Black to exchange his so-so knight for my excellent light-square bishop on move 18, which marks the real strategic turning point of the game.  One of the things Class players often lack is a sense of the importance of piece exchanges and this game is an excellent illustration of the consequences.  Black immediately obtains the initiative and the bishop-pair, allowing his pieces to spring to life and target what are now some obvious White weaknesses.

Despite White's forced retreat, Black misses some chances to leverage his positional advantage for tactical gains (including 23...Bb5!) and White re-achieves equality, making a draw offer that is rejected.  Nowadays I've given up the practice of early draw offers in favor of emphasizing mental toughness, but even then I have to admit it was rather rude, given the ratings gap, not to mention being overly optimistic.  Indeed, a few moves later White plays the complacent 27. Nd3? and this time Black does not miss his chance to inflict material losses on White, who eventually loses after trading down into a bishop (for Black) endgame.

Although this was a loss, the game in fact left me in a relatively positive mood for the rest of the tournament.  I had made a 2100+ player sweat through the early middlegame and did not simply collapse after his first counterblow.  This positive frame of mind helped in my later games.  This was also the first tournament I played in after beginning to train with Qigong breathing exercises (part of my Taijiquan martial arts practice), which also appeared to have a positive effect on my mental outlook.  More on that later.

A robust and deep insight on playing style

I finally tracked down the original reference from Playing Styles Deconstructed that underpinned what I termed the impracticality of pursuing a chess "style" for improving players.  The following is from GM Alex Yermolinsky's The Road To Chess Improvement (Gambit 1999).
...One strong GM once told me that during the game we (he meant World Top 100 or so) may happen to know, able to calculate, or in any other way find the best move in approximately 90 percent of positions.  This means that, if an average game lasts 50 moves, there will be 5 times during the game when we won't know what to do!  There comes the most interesting, yet difficult part.  He also said that these moments are very characteristic for a chess-player's style and personality.
I find this to be a robust and deep insight.  In the linked post, the primary lesson I took away was that attempting to conform to some idealized type of playing style ("tactical" or "positional" or whatever), especially at the Class level, would be an impediment to the improving player. What we really need to do instead, along the lines of the above quote, is focus on reducing the number of positions where we don't know what to do!

Another important aspect to the above-quoted idea is the concept that it is normal to have differing opinions over positions, even at the top level and to the point where you do not in fact understand all aspects of the position.  It's been remarkable to me how often the very top-rated players will candidly express this during interviews or in post-game analysis, for example in How Kramnik makes us feel better about chess.  I have seen Carlsen and Anand be similarly self-effacing and the lack of ego in the top ranks these days is very refreshing, as well as motivational for me to see.

A final comment on style: assuming the idea above is broadly true, our personal style will naturally shine through as part of a game's development, giving scope for creativity and individuality.  But  that does not excuse us from increasing our efforts at objective investigation and understanding of truth on the chessboard.
