573. Bilgisayar Satrancı. Arasan

Arasan 13.1 64 bit sürümü ile bir sınama denemesi gerçekleştirdim. Sınama konumu dünkü Alekseev-Ivanchuk oyunundan alındı.

Arasan 13.1 64 bit, doğru hamle olan Kd7+ hamlesini buluyor; pv olarak Kd7+ Şc8 Kd3+ Şb7 Kxe3 Fh4+ Şxh4 ve yenişmezlik değerlendirmesinde bulunuyor. Ancak Kd7+ Şe8 hamlesi oynandıktan sonra pv yenileniyor!

Şe8 hamlesinden sonra Kd1 Fb8 Şf7 esas sürdürüm olarak veriliyor ve değerlendirme siyahlar lehine değişiyor.

568. Dünya Kupası XVIII

Three Opening Disasters from the World Cup Round 2 Game 1

Mark Crowther - Wednesday 31st August 2011

Three games were virtually decided in the opening in the first game of the second round of the FIDE World Cup in Khanty Mansiysk. Vugar Gashimov's preparation against Sergei Azarov's Jaenisch variation of the Ruy Lopez was spot on. Gashimov played the whole game very nicely. Nikita Vitiugov thumped Anton Korobov in a Moscow Variation when he played a known bad move. Alexei Shirov was in difficulties early in a sideline of the Botvinnik Variation and his position went under quickly through nice play from European Champion Vladimir Potkin.

Nikita Vitiugov demonstrated the perils of lack of precision in the Moscow Variation to his opponent Anton Korobov. | http://chess.ugrasport.com

Three Opening Disasters

Sergei Azarov was well beaten by Vugar Gashimov Photo © FIDE World Cup Khanty Mansiysk 2011 Website

Vugar Gashimov crushed his opponent Sergei Azarov in just 23 moves. Gashimov had noted that Azarov had already played the Jaenisch variation of the Ruy Lopez in the first round and he thought this must be his special preparation for the event. So Gashimov prepared the interesting idea with 6.Be3 which had only been played once before. 6...Bb4+ was already new, 8...bxc6 already lost a pawn, although even with the better 8...dxc6 white has a big advantage. Gashimov finished things with a nice sacrifice 17.Ng6+.

Based on brief comments by Gashimov

1.e4 e5 2.Nf3 Nc6 3.Bb5 f5 4.d3 fxe4 5.dxe4 Nf6 6.Be3

Nikita Vitiugov played a very straightforward refutation of 13...Bg7 the Moscow Variation of the Semi-Slav. It seems that Anton Korobov probably just mixed up his lines somehow.

Korobov forgets the theory. Now white has a crushing position. This analysis was already known and pointed out by Konstantin Landa during commentary as soon as he saw this move.

European Champion Vladimir Potkin was so preoccupied with his playoffs for round 1 that he didn't realise who he was playing until he had finished. He said "My long tie-break games actually helped me gain energy for today." Today he crushed Alexei Shirov who got into a miserable position early on and Potkin made no mistake.
