Re: Topalov vs Anand Gmae 8

Re: The brilliant chess move (65)

Stockfish 1.7 even finds the best move rather soon with Zugzwang detection on and maximum Aggressiveness (200 instead of 100), but then gets stuck with 9.a6 instead of Kc8. Analysis by Stockfish 1.7.1 JAAZ: 1.Te8 gxf3 2.a...

Re: The brilliant chess move (643)

Did you notice the depth? On a low end quad like mine (4x2.5Ghz, 1024 Mb hash) R3 takes about five times as long to reach 20 hp in this position.
