Re: Gaviota, Wasp, The Baron, Pro Deo

Actualy, Stockfish 8 slightly prefers 36. Be5 too (0.00; other moves are -1.21 at best, except 36. Re1+ Kd7 37. Be5 that's 0.00 too). White makes this sac in order to distract Black's knight from attacking the c-pawn, whose loss would be undesirable for White as it would create a protected passer fo...

Re: Stockfish no progress in 2month and half , why ?

Sugar is Stockfish dev clone. So this is more the rating of Stockfish dev than something else. Oh, it's great to hear that SF's dev is noticeably better than the stable version :) What's bugging me is that the SF brand is erased from the leaderboard. It's a minor annoyance for the authors as SF is ...

Re: Stockfish no progress in 2month and half , why ?

Breaking news: in today's update of the CCRL 40/40 rating list, SugaR XPrO 1.2 64-bit 4CPU has got a 3413 rating based on 292 games and is now considered the best version of SF at 40/40 (not at 40/4 yet), erasing SF itself out of the 40/40 index and pure leaderboard (that list only 1 version per eng...

Re: Is the rating of top player overrated ?

Yes, indeed. I guess that some of them weren't motivated enough, especially Carlsen, who didn't have to be a finalist to qualify for the next championship match and, to make things 'worse', has apparently recently got into a romantic relationship stealing some time and energy from his chess study. S...

Re: But Fizbo have a big technical problem!

No problem - several days are a negligibly small timeframe in comparison with the typically long and hasteless careers of computer chess enthusiasts :wink: The upcoming release of Fire 6 is a cool news, I hope its aggression hasn't been reduced from v.5. As for Romi, I ran a 10-game mini-match with ...

Re: Is the rating of top player overrated ?

Specifically in a KO tournament, one of the main reasons why strong players lose rating points is that they play it safe. To advance to the next round, it's enough to score 1.5:0.5 and often even 1:1 in the classical part because their advantage in the tiebreaks is big enough. Thus a strong player o...

Re: 32-Bit?

A knight handicap with (in game 2) 1 core and 32 MB hash still don't help - Fizbo just sees much deeper every time. Here's the critical position of game 2. [d]r1q1kb1r/1p3ppp/1P2p3/p1Pp4/4b3/1Q3NP1/1B1KPPBP/2R5 w kq - 3 16 16. Ne5!! f6 (16... Bxg2 17. Qa4+ Ke7 18. c6 d4 19. cxb7 Qxb7 20. Rc7+; 18......

Re: 32-Bit?

I said that Romi wasn't seeing it because, in the PV to the 24th move, she wrote just, '-1.53/6 e1d2 f1a1' - actually, she wasn't seeing that, after 24... Qxa1? 25. Qxe5+, White would be giving perpetual. By playing 24... Nb1+ (a desperado), Fizbo saved the king from it, making Qe4+ or Qf5+ impossib...

Re: 32-Bit?

(Romi seems to have a bigger than normal appetite for the a8 rook :P ) Especially stunning was the somewhat hidden point behind Fizbo's move in the most critical position (Black to move): [d]5r2/Bp2k1p1/1N5p/4p3/1b2n1b1/2PQ2P1/PP3PqP/R3KR2 b Q - 0 19 19...

Re: 32-Bit?

Poor Fire :D When playing through the game, I was puzzled as to why Fire had to give up the queen for the g2 rook - obviously, it couldn't play 47. Qd1 (that loses to 47... Rxh2+ 48. Bxh2 Nf2+ 49. Kg1 Nxd1 50. Rxd1 e3! 51. Rxe3 Qc2), but the analysis of 47. Qf1 is less trivial - I guessed correctly ...
