SHUT DOWN YOUR CHESS ENGINE AND THINK FOR YOURSELF || Viswanathan Anand believes that serious followers of chess will be better served by switching off their computers once in a while in order to understand the flavorful ‘human elements’ of the match

Computers have shortened the learning cycle

Computers have shortened the learning cycle - Interview with Grandmaster Anish Giri. He became the youngest Grandmaster at the age of 14 years and seven months in 2009. And earlier this year, he finished joint second at the prestigious Tata Steel Chess Tournament in the Netherlands. He has also been the Dutch national champion three times. His father hails from Nepal and his mother from Russia, the country where Giri was born and where he took his first lessons in chess. His father’s work brought the family to the Netherlands, a country which is proud of him now and celebrates him as a sports icon. Giri is a contributing editor to the leading ‘New in Chess’ magazine and his first book ‘My Junior Years in 20 Games’ was recently published. He is refreshingly humble in acknowledging that he was lucky at important turns, which helped in his rapid rise. CLICK HERE FOR ENTIRE INTERVIEW

My HIARCS chess software has never seen a game like this

The Gashimov Memorial Tournament from Azerbaijan will be on early in the mornings starting Thursday. Try the usual sites. || || My HIARCS chess software has never seen a game like it, at the conclusion of the analysis, a pop-up window informed me, “HIARCS makes no improvements”. That’s right, none of the moves by EITHER player exceeded the parameters( HIARCS is set at a quarter of a pawn) that required the software to comment. If there were no pop-up window, I would have thought the software had malfunctioned and I would have run it again to try to get it to work. This error-free game logically ended in a draw, so were the players who fought it grandmasters of the highest caliber? No. Were they the actively proficient masters you might expect to encounter in a state championship event? No. These guys were just the sort of competitors you’d expect to find in the $5,000 first prize class A section of the Philadelphia Open. If you always suspected that one had to be about master-strength to win a big A prize, the HIARCS chess software certainly agrees with you. I had to use the Stockfish program to find any different moves at all, and you can see from the evaluations that they weren’t particularly significant. So my congratulations to the players of this game, and let it serve to remind the rest of us to never underestimate our opponents. || [Event "2015 Philadelphia Open"] [Date "2015.04.04"] [Round "3"] [White "Likhit Ganedi"] [Black "Jarett Dewelde"] [Result "1/2-1/2"] [ECO "B00"] 1.e4 Nc6 2.d4 e5 3.dxe5 Nxe5 4.Nf3 Nxf3+ 5.Qxf3 Qf6 6.Be2 Bc5 7.Nc3 d6 8.Nd5 Qxf3 9.Bxf3 Kd8 10.b4 { Stockfish: 10.0-0 Ne7 11.Nf4 Ng6 12.Rd1 f6 13.Nd5 +.24 and 10.Bf4 Ne7 11.0-0-0 Nd5 12.Rd5 Be6 13.Rd2 is +.19 and 10.Bd2 Ne7 11.Nf4 f6 12.Bh5 c6 13.0-0 is +.20 } 10...Bd4 11.c3 Be5 12.Bf4 { Stockfish 12.Bg5 f6 13.Bd2 c6 14.Ne3 Ne7 15.Be2 +.25 } 12...Bxf4 13.Nxf4 Nf6 { 13...g5 14.Nh5 Ke7 15.Be2 Nf6 16.Nf6 Kf6 17.f3 Rg8 18.Kd2 a5 and Black is only losing by .05 } 14.O-O-O Re8 15.Rhe1 Ke7 { Here Stockfish plays 15...Ng4 16.Bg4 Bg4 17.f3 Be6 18.Kb2 Kd7 19.a4 a5 and White is winning by .05 } 16.e5 dxe5 17.Rxe5+ Kf8 18.Rxe8+ Kxe8 19.Nd3 a5 { Stockfish plays 19...Rb8 20.a4 Ke7 21.a5 Bf5 22.Re1 Kf8 23.Ne5 Kd7 24.Kb2 and White is winning by .32 at 34 ply. } 20.b5 Rb8 21.a4 { Stockfish prefers 21.Kb2 Ke7 22.c4 Be6 23.Re1 Kd6 24.Kc3 Nd7 25.Kd4 b6 +.28 } 21...b6 22.Ne5 Be6 23.Nc6 Rc8 24.Kb2 { Stockfish says 24.Nd4 Bd5 25.Bd5 Nd5 26.Kc2 Nf6 27.Nc6 Nd7 28.Re1 Kf8 29.Ne5 Nc5 30.Nd3 Nd3 31.Kd3 Rd8 32.Kc2 Re8 33.Re8 Ke8 is 0.00 equal at 36 ply. } 24...Kf8 25.Ne5 Ke7 26.Nc6+ Kf8 27.Ne5 { Stockfish says it's 0.00 here, the ending 27...Ke7 28.c4 Nd7 29.Nd7 Bd7 30.Rd7 Kd7 31.Bg4 Kd8 32.Bc8 Kc8 33.g4 c6 34.Kc3 Kd7 35.f4 Kd6 36.Kd4 g6 37.bc Kc6 38.g5 Kd6 39.h3 Kc6 40.Kd3 Kc5 41.Kc3 Kd6 42.Kd4 is a draw. } 1/2-1/2 || Alan Lasser, web site: || email:

Alan Lasser Game of the Week

 After I hung a pawn, I managed to live to the ending, but I was down some minutes on the clock, so playing to hold the rook and pawn endgame was exciting.  I was moving too fast to see that I could have gone a pawn up, albeit the notorious bishop pawn, the one that could be a draw except that the defender usually messes it up.  So it was a good thing I didn’t notice, I probably would have lost on time.
