Re: The blitz picture

Maybe someone has such games? Hi! What about rating- list- matches? GEGT, CCRL... E.g. also Stefan Pohl with his LS- tournament might have much material for you, I guess. Quite at the end of his hp http://ls-ratinglist.beepworld.de/ there's a link to a contact- formular. http://www.beepworld.de/cgi...

Re: Is it actually a draw?

Play the PV moves to get more insight. From your initial diagram: 1...Kg7 2.Qa7+ Kg8 3.Rg3+ Rg6 4.Qb8+ Kf7 5.Qc7+ Kg8 6.Rh3 Rf6 7.Qb8+ Kf7 8.Qb7+ Kg8 9.Qg2+ Kf7 [D]8/5k2/5r2/1p3q2/5B2/7R/6QK/8 w - - You will find a "M1000" score which indicates a Syzygy win. Both Bg3 and Rh4 appear to be winning, q...

Re: very hard test position for stockfish from my game

Calling tbs a dirty tool can be seen so, if you think humans as well as engines should be able to solve any tbs- position on their own alone, but I for myself am not as ambitious as that, and then it's still a matter of time, how fast you're able to. :) Yet as for Persistent Hash as Jeremy Bernstein...

Re: very hard test position for stockfish from my game

Hi Marek!
Did you ever think about using Jeremy Bernstein's ways of Stockfish PA_GTB with Gaviota's tbs and Persistent Hash?
I think such a kind of Sting Stockfish would be an even greater tool maybe, especially for corr. chess, don't you think so too?

Re: very hard test position for stockfish from my game

We weren't sure yet also some discussion in the Googlegroup if there is any Zugzwang involved in not finding the perpetual. Sting is better at finding Zugzwangs but that does not have to be the reason here I suppose, I would not immediately associate the position with Zugzwang. Not in the first pla...

Re: FIDE World Chess Championship thread.

SO , if it is true at 46...Rg1 black is lost and at 51...Re2 draws, in between rhose moves Carlsen blundered. You're right, Ignacio, IF it WAS true, but I'm rather sure, it WAS and it IS NOT. :) Here is H3's output after 45th white move, 45...Rc1 has the same eval as 51.Re2 has after the 50 moves p...

Re: FIDE World Chess Championship thread.

If I was walking in Anand's shoes,I will resign on the 48th move.... You would have lost your half point more than you should have, like Anand did, Dr. Deeb, but he didn't before move 51...
