Cheater-1 Analysis

1.d4 The annotations and lines are by no means everything that went through my head during the game. I'm also adding computer analysis to round it out as usual. 1...Nf6 2.c4 e6 3.g3 d5 4.Nf3 dxc4 5.Bg2 b5 6.a4 c6 7.0–0 Bb7 8.Ne5 Qb6 9.e4 Be7 10.Be3 Qc7 11.b3 This is where we leave opening book. Our motivation is obvious. We want to begin breaking down the pawn jam but with the deeper intention of developing our pieces and readying our forces for action in the center. 11...cxb3 12.Qxb3 Nbd7 13.axb5 Nxe5 14.dxe5 Qxe5 15.Qc3 This is where we leave previous game theory. This move has a deep diabolical motive. I wanted a queenless game so that the endgame would featureprominently. Humans do better in this department. We actually perform better with less resources. It also gains a tempo by chaining the Nb1 into the fray. 15...Qxc3 16.Nxc3 a5 17.Rfc1 There was considerable debate over the correctness of this move. It sets the tone for many moves to come. 17...cxb5 18.Nxb5 0–0 19.Rc7 Ba6 20.e5 Nd5 21.Bxd5 exd5 22.Nd6 You can see why I wanted the Rc1. This lead to a long virtually forced series of moves. [22.Nc3 Bd8 23.Nxd5 Bxc7 24.Nxc7 Bc4 25.Nxa8 Rxa8 This leads to a slight disadvantage because the outside passer is not contained and is slightly better anyway. The second reason I wanted to avoid this is because it was simply a draw.] 22...Bxd6 [22...Bd8 Could Black play this? No. See the lines that follow. 23.Rd7 Bc8 24.Nxc8 Rxc8 25.Rxd5 Rc2 26.Bc5 a) 26.f4 Bc7 27.Rc5 Rxc5 28.Bxc5 Rc8 29.Rb1 (29.Bd4 Bd8 30.Kf2 Rc2+ 31.Kf3 f5 32.exf6 gxf6 33.Rb1 Kf7 34.Rb8 Be7 35.Ra8 Rc4 36.Ke3 Bc5 37.Bxc5 Rxc5 38.Kd4 Rb5 39.Kc4 Rb2 40.Rxa5 Rxh2 41.Kd4 Draw) 29...g5 30.Be7 gxf4 31.gxf4 Bd8 32.Bd6 Bc7 33.Bxc7 Rxc7 34.Rb8+ Kg7 35.Ra8 Draw; b) 26.Rd2 Rxd2 27.Bxd2 Bc7 This does give us an advantage but is it enough?; 26...Re8 27.Rb1 Bg5 28.Rb7 (28.f4 Bh6 29.Ba3 (29.Bb6 a4 30.Ra1 Rc6 31.Bc5 Ra6 32.Rd4 Rea8 33.Kg2 (33.Ra3 f6 34.Bd6 fxe5 35.Bxe5 Draw) 33...f6 34.e6 Rxe6 35.Rdxa4 Rxa4 36.Rxa4 g5 Small advantage but a draw is likely.) 29...g5 30.fxg5 (30.f5 Ra2 31.Bc5 Not enough here so just a draw.) 30...Bxg5 31.Rxa5 f6 32.Bd6 Re2 33.h4 Bd2 34.Rd5 Bc3 35.exf6 Bxf6 36.Rb8 (36.Rf1 Kg7 37.Rdf5 R8e6 38.Bc5 Rd2 39.Bf2 Advantage White.) 36...Kf7 37.Rxe8 Rxe8 38.Kg2 Rd8 39.Rd2 Ke6 40.Bf4 Rxd2+ 41.Bxd2 Kf5 42.Kf3 h5 Advantage White.) 28...h6 29.h4 (29.f4 Rc8 30.Bb6 Rb2 31.Rc7 Rd8 32.Rxd8+ Bxd8 33.Rc8 Rxb6 34.Rxd8+ Kh7 35.Ra8 g5 36.Rxa5 gxf4 37.gxf4 Kg6 38.Kf2 Kf5 39.Ra4 Rb2+ 40.Kg3 Rb3+ 41.Kh4 Rf3 Equal but not good.) 29...Bd2 (29...Bc1 30.Bd4 a4 31.e6 Rxe6 32.Rd8+ Kh7 33.Rxf7) 30.Bd4 Bb4 31.Rdd7 Rc4 32.Kg2 a) 32.Rxf7 Rxd4 33.Rxg7+ Kh8 34.Rh7+ Kg8 35.Rbg7+ Kf8 36.Rg6 Rxe5 37.Rgxh6 Re7 38.Rh8+ Kf7 39.R8h7+ Ke8 40.Rh8+ Kd7 41.Ra8 Rc4 42.Kg2 Rc6 43.Ra7+ Rc7 44.Raa6 Ke8 45.h5 Kf8 46.f4 (46.g4 Rg7 47.Rhf6+ Kg8 48.Kg3 Rc3+ 49.f3 Rc4 50.h6 Rb7 51.Rfe6 Kh7 52.g5 Bd2 This was well worth the look. The three pawn theme against a rook appears in another opening so I though I'd look here too. Equal.) 46...Rf7 47.Kf3 Rc3+ 48.Kg4 Rg7+ 49.Rhg6 Rxg6+ 50.Rxg6 (50.hxg6 Kg7 51.f5 Not good enough.) 50...Kf7 51.f5 (51.Ra6 Rd3 Black is too fast here.) 51...Rc4+ 52.Kf3 a4 53.h6 a3 54.Rg7+ Kf8 55.Ra7 Rc3+ 56.Kg4 Kg8 57.f6 Rb3 Worth checking out.; b) 32.Kf1 Re7 33.Rxe7 Bxe7 34.Rxe7 Rxd4 35.Ra7 a4 36.f3 Intersting but perhaps a draw at best.; 32...Bf8 33.e6 f6 34.f4 (34.h5 a4 35.Ra7 Rxd4 36.Rxd4 Bc5 37.Rdxa4 Bxa7 38.Rxa7 Rxe6 39.f4 Rd6 40.g4 Rd3 Dead draw.) 34...Rxe6 35.Rb8 g6 36.g4 Rec6 37.Rdd8 Kg7 38.g5 Winning for White.] 23.exd6 There are two ideas here. Obviously a lot of play will revolve around the passer because it's so close. Second, it is said that in Bishops of Opposite Colour the attacker is favoured. 23...Rfd8 24.Bc5 We reach the end of the forced moves and Black is confronted with a mountain of deep posibilities. What we've done here is to use the computers contempt for a draw rather well. Now we plunge the operator of the computer in over his head! 24...Bc8 You will see the sac RxB hidden in the notes repeatedly throughout the game. This was a major feature and was also what caused the game to take the direction it did. [24...Be2 25.Re1 (25.f3 Bxf3 26.Rf1 Bh5 27.Rf5 Bg6 28.Rxd5 Be4 29.Re5 Bg6 30.d7 f6 31.Rd5 Kf7 32.Bb6 Ke6 33.Rd4 Ke7 34.Rc3 Bf5 35.Re3+ Kf7 36.Bxd8 Rxd8 37.Ra3 Rxd7 38.Rxd7+ Bxd7 39.Rxa5 Kg6 40.Kg2 h5 41.h4 Bg4 42.Kf2 Bc8 43.Ke3 Kh6 44.Ra8 Bg4 45.Ra6 Kg6 46.Kf4 Kf7 47.Ra7+ Kg6 48.Ra8 Be6 49.Re8 Kf7 50.Rb8 Kg6 51.Rh8 Bg4 52.Re8 Kh6 Won.) 25...Bg4 (25...Bf3 26.Re3 Be4 27.f3 Bf5 28.Ree7 Be6 29.f4 h5 Crushing.) 26.Ree7 Be6 27.f4 g6 28.g4 a4 29.f5 gxf5 30.gxf5 Bxf5 31.Rxf7 Bg6 32.Rf4 Crushing again.; 24...Bc4 25.f3 g6 (25...h5 26.Kf2 a4 27.Ke3 Kh7 28.Kd4 Kg6 29.h4 (29.Rb7 f6 30.Ra3 A solid advantage for us.) 29...f6 30.Rb7 Kh6 31.Ra3 Kg6 Same thing.) 26.Kf2 a4 27.Ke3 Kg7 28.Kd4 h6 (28...Ra5 29.h3 h6 30.f4 Raa8 31.g4 Ra6 32.g5 h5 33.Rb7 Raa8 34.h4 Kg8 35.Ra3 Kg7 36.Re3 Ba6 37.Rc7 Bc4 38.Ree7 Rf8 Easily winning.; 28...Kf6 29.Re1 a3 30.d7 a2 31.Be7+ Kg7 32.Bxd8 Won ending.) 29.Rb7] 25.f3 The variations are computer. I was so sure about this move that I added the computer stuff just now. Might as well keep the commentary balanced. But, my gut feeling was this was the right path. We had to keep the game alive by giving his program just enough advantage so that it wouldn't dive for a draw. This move has multipe functions. In the even that we are able to run our king up there would be no way for Black to get a rook on e4. There is a possibility of a mate trap when our king reaches e5. Something we must bear in mind. It also takes away one more square from his bishop. That bishop is the subject of a restriction theme that helps level the game.

Black runs the king up there to queen and we are totally offside.) 45...Kf7 46.Rb8 d4+ 47.Kb6 Bf5 48.Bxd4 This is good for White but is it enough.

The idea here would be Rb7 then Ra7. 27...a3 28.Rbb7 a2 29.Ra7 a1Q] 27...Rdb8 Again we present him with a mountain of choices. I'll leave those for you to examine. My general feeling was that our plan would prevail so only the text was good for Black. Remember that often a position suggests multiple moves but no plan. The guy playing with the plan only needs to consider the moves he needs to fullfill it. I looked at these just out of caution because even the smallest miscalulation would cost us the game.

This move is defensive and offensive. By moving everything up to the 3rd rank and beyond we close the gap between our passer and our rook.

As you can see I just kept coming up with ways to keep material on the board while setting traps through most of the game. Many times we could have forced a draw with sudden exchanges so why did we play on and on. I judged that our opponent would play on largely in part because of his programs contempt for the draw but also because of his intense desire to beat us. A cooler head would have taken the draw but this is E postal chess so we don't tire as easily. I could see all the draws from here and fully expected that this would be our last attempt a a trick. There was a slim chance that he would take the bait and misjudge his defensive needs. At this point I was playing the man more than the machine. Black has to make a choice of how to repeat the position or to play Rb5. This would have allowed us to play on a bit more and perhaps come up with one more logic trap for his computer. 35...Bxh3 -0.35/9 0 [35...Rb5 36.g4 Ra5 37.f4 hxg4 38.hxg4 Bd7 39.Bb6 f6+ 40.Kd4 Ra6 41.Bc5 Bxg4 This looks good for Black.] 36.g4 hxg4 [36...Rb7 37.Kxd5 Bf1 38.Kc6 Rb4 39.gxh5+ Kxh5 40.Bxg7 Bb5+ Again, just a draw.] 37.d7 Rb8 38.f4 I can only conclude that something went wrong with his program. Yet, how do I justify the fact that he didn't override the computer? Perhaps he didn't see it either and was still playing to win. 0–1

Sorry No diagrams because my connection is too slow.
