Re: On-line engine blitz tourney August

It seems (even) Komodo needs considerable depth to to see this. Pretty impressive if ArasanX finds it in a 5'+1" blitz game!

Re: On-line engine blitz tourney August

WaDuuttie achieved an acceptable score this time because in the last round in this position
[d]8/5p2/p4Pk1/6P1/1p2K2P/1P6/3p4/2bN4 b - - 0 56
ArasanX played Ba3 and to my surpise resigned ! WaDuuttie thinks he is only slightly better and certainly not winning yet ... so what did ArasanX see ?

Re: Quiescence Search Performance

Another way of looking at these "problem-positions" is calculating their capture-perfts for different depths. For this I replaced in the perft-routine the funcion generate() by generate_captures() as used in qs (only captures and promotions to a queen are generated). [d] rr4k1/bb2q3/p1n1p3/3p3p/1P1P...

Re: Quiescence Search Performance

And another one. Feel free to check if these are pathological cases for your QS, too.

[d]8/8/4kpp1/3p1b2/p6P/2B5/6P1/6K1 b - - 0 1 None of the engines did find Shirov's elegant 1...Bh3 giving withe at least some hope for a draw. Curious what the big-boys will do here. Well, the "big-boys" are done with this position. Of the 56 games played, 42 continued with 1...Be4 (score 0-18-24) ...

Re: CENT - MAIN Pool started

WaDuuttie needs over 762 million nodes (and more than 6 and a halve minute on my system) to see the right move: FEN: 8/4K2p/6pr/5pk1/1pB2R2/p4PP1/8/8 w - - 0 1 ... 33 05:13 611,483,727 1,950,444 0.00 c4d5 h6h3 f4b4 h3g3 b4a4 h7h5 a4a3 h5h4 a3a8 g5f4 e7f6 g3g1 a8h8 g6g5 h8h6 g1d1 d5e6 d1d6 h6h5 f4f3 ...
