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 ...

Re: 32-Bit?

Still not 32-Bit versions? Of ANY Fizbo? :cry: Oops, forgive me, please - I hadn't read the threads about the previous versions. Youri did tell in the v.1.6. thread why there will never be a 32-bit version : No, no 32 bit version. All the code has been based on 64 bit data structures from day 1. Yo...

Re: 32-Bit?

Fizbo's author has a LinkedIn account (as acknowledged in the CPW ), try asking him there. Meanwhile, I'm experimenting with various ways to set up a handicap in Fizbo vs Cheng blitz (3+3) games. It turns out that forcing Fizbo to play the Latvian gambit ( :P ) doesn't fully compensate for the >200-...

Re: But Fizbo have a big technical problem!

SF8 thinks that Black's 25th move was the moment when iCE made a mistake - played 25... b4 (0.00) instead of 25... Ra7 (-1.23) and allowed Fizbo to force a draw. For White's 26th move, with contempt set to 100 and MultiPV to 4, SF gives 26. Rxh6 as the only move that's not worse than -1.00 (i.e. the...

Re: But Fizbo have a big technical problem!

Amazing!!! :o I'll now show this game to SF 8 to find out if the draw was inevitable. If iCE had feelings, it would be so happy with the outcome. Thanks for gathering several aggressive engines in the same division of the series - I'll keep an eye on the PGN links that you'll be posting. This divisi...

Re: But Fizbo have a big technical problem!

Thanks for the link, that game was brilliant! Fizbo definitely has a talent for pawn promotion tactics. It often sees an opportunity to give up a minor piece when it allows to create connected passers that are worth a rook. It looks as though its static eval gives more importance to passers than tho...
