Human Interaction in Correspondence Chess

Schachmatt - Omprakash

Result: 1-0
Site: ChessPlanet
Date: 2011
This was my first game of Round 1 in WBCCC 2011 which was conducted in Chessplanet server. This particular game has given me insight that how a human is always superior in finding deep tactics involving positional sacrifices. This game is a prime example of that. I used Rybka Aquarium GUI and 4 single core Houdini 1.5a x64s to analyse on my fast i7 machine. [...] 1.e4 c5 2.¤f3 d6 3.d4 cxd4 4.¤xd4 ¤f6 5.¤c3 a6 6.¥e3 e5 7.¤b3 ¥e6 8.f3 ¤bd7 9.g4 b5 10.g5 b4 11.¤d5 ¤xd5 12.exd5 ¥f5 13.¥d3 ¥xd3 14.£xd3 ¥e7 15.¦g1! O-O! 16.O-O-O a5!! 17.¢b1!! Here f5!! is the best move. I wanted to go out of book here. So I played aiming on the attack on the King which I always like to do.
(17.¤d2!! a4 18.h4!!17.¤d2!! a4 18.h4!! (18.¤e4? £a5!) (18.¦g4!?) )
17...a4!? 18.¤d2 £a5! 19.¤e4 ¦fc8!? 20.h4 £a6? After a long analysis I felt I should exchange queens to my advantage.
21.¦g4!! This particular move says that queen exchange is not feasible if you are playing for a win.
21...£b7 Now I changed my mind!!. I now was in a mood for attack.
22.h5! Now here My king is in danger and I am unaware and my engines too. Rab8 or Ra5 was the correct reaction.
22...¦c7?? I wanted to double the rooks before playing b3. But what a Blunder ? I analysed 2 whole days In IDeA but with LESS HUMAN INTERACTION and found my plan to be great. None of the Engines I have Including Rybka , Houdini, Hiarcs, Shredder, Junior , Stockfish, Fritz , Robbolito and family, Ippolit and family and Spark found that Rc7 was damn good blunder. Score was equal. So i opened my XFCCPlay and eneterd the move Rc7. But suddenly before confirming the move I thought of the move g6!!. What happenes next ? Nothing becoz after 23.g6 fxg6 24.hxg6 h6? nothing is happening and I am holding the attack??. What a mess. I confirmed Rc7??
23.g6!!ќ None of the engines find this move Interestingly. They think Rdg1?? as best!!
23...fxg6 24.hxg6 h6??
(24...h5?? 25.¤g3!! Leaving the rook and winning. (25.¤xd6!!ќ) 25...b3 26.cxb3 axb3 27.a3 £c8 (27...¤f6? 28.¦b4ќ) 28.¤xh5 ¦c2 29.¦h1!!ќ)
25.¥xh6!! Many engines don't find it either. I saw this move when I played 24...h6? but missed 26.Qe3!! and the coming queen sac
25...£b6 To stop Qe3 but again I found.....
(25...gxh6?? 26.£e3!! b3
(26...¢g7?? 27.£xh6!! ¢xh6 28.g7!! ¥h4 29.¦h1 ¤f6 30.¤xf6 ¦xg7 31.¦hxh4#)
27.cxb3 axb3 28.a3 ¥g5 (28...¥f6 29.g7!!ќ) 29.¦xg5!!ќ)
(25...b3 26.cxb3 axb3 27.a3 ¤f6
(27...¥f6?? 28.¥g5 (28.¥xg7!? ¥xg7 29.¤xd6!ќ) (28.¤xd6!?) 28...¥xg5 29.¤xg5)
28.¥g5
(28.¤xf6 ¥xf6 29.¥g5!ќ (29.¦b4!!ќ) 29...e4 30.fxe4 ¦c3!? 31.£f1 £c8 32.¦g2!!ќ ¦g3 33.¦c1 £g4 34.¦xg3 £xg3 35.¥xf6 £xg6 36.¥c3 £xe4 37.¢a1 £g4 (37...£xd5 38.¥xg7ќ) 38.£g1!)
28...¤xg4 29.fxg4 ¥xg5 30.¤xg5 ¦ac8 31.¦h1 ¦c1 32.¦xc1 ¦xc1 33.¢xc1 £b6 34.¤e4 £g1 35.¢d2 £b6 36.£c3!± Mate in 22)
26.¥xg7 I am Happy that I lost this game. I learnt a important lesson. Until and Unless a human guides an chessprogram to a concrete plan they are useless. As a human I would have played g6 or may be Bxh6 but it wasn't easy to find Qe3 which was winning. But then Engines see the Light. I found Stockfish at Agressiveness 200 and cowardice 0 find g6!! and the Bxh6!! sac immediately!!.
