Re: Sting SF 4.8.4 correction

I have a little tested. [d]r2qrb1k/1p1b2p1/p2ppn1p/8/3NP3/1BN5/PPP3QP/1K3RR1 w Here Sting sf 4.8.4 takes 2h30 to find e5. Houdini 4 is finding in 10s and StockFish 6 in 1mn. This is kind of progress which should have to do Sting. Sting's main point is endgame without tablebases. Marek believes engi...

Re: Binders

I am not an expert about evaluation positions but i agree with your claims Lyudmil but other way. I play exactly same style like yours unlikely classical chess. I play chess like a real war. Do you really use your important soldiers first ? or try to keep them for another/important situation ?. I li...

Re: Sting-sf-48 release

Hi Dann I just tried the 64 bits compile, and noticed that Sting time management is very bad. It just lost the game on time in completely won position. Can Sting time managemnt be improved, so it doesn't lose games on time ? This engine is created for analyze actually not for engine ve engine maches.

Re: any UCI pure brute-force engines?

I tried it with my new idea (Sting-sf-48, hash 1024M, dual core) without some dirty "Monte Carlo" or "rule50" or "nullMove search disabled" or "tablebases". (time 5 second!)

Re: any UCI pure brute-force engines?

[D]8/1pN4r/5pkp/8/5K1p/2P4N/P3Bn2/8 w - -[/D] Bh5+ wins. None of top engines could solve it. I guess that search techniques like null_move_pruning or futility_pruning are responsible for that blindness. Is pure brute_force the only chance to solve it? And if so, what UCI compatibile engine could yo...

Re: Which move is better and why ?

Thanks for those analysis people. I know this is not a good test position as i said it's little bit silly however but Artista showed +0.43 for white both of Nc7 and Nd7. Na6 is +0.40. When score not changed after deep searching i wanted to ask this question. Stockfish evaluated differently those mov...
