Re: Which is the weaker engine that can find the draw in gam

<from a wiki article> However, it was discovered in 2007 by Internet analysis[7] that after 45...Qe3 46.Qxd6 Re8 47.Qd7+ Re7 48.Qc6 Qxe4 49.d6 Qd3+ 50.Kg1 Re8 51.Ra1 there is no perpetual check and the attack continues. The critical move being for White to force Black's rook on e7, which is later a...

That would be T&R for Unix, R for C (T did B) and K&R for the book on C?

Re: Which is the weaker engine that can find the draw in gam

45. ... Qe3 and 46. ... Re8 should be easy finds nowadays even if the draw is still far away. Recognizing upcoming repetition in leaf nodes could be of good help in this kind of positions with exposed king vs. queen. I think the real question is what program still plays 44. Kf1? Modern evaluation fu...

Re: Discocheck "Boney M" is out

After Doublecheck 3.4, I renamed my engine Discocheck (starting with 3.5). Many reasons for that choice: - what used to be double check extensions and specific treatments in the search, actually became discovered check instead. - Discocheck is chess slang for discovered check - it contains disco an...

Re: Vayser-Overton, WC35/sf12 ICCF 2011

[D] 2b3r1/8/1kp1p1P1/2b1P2B/1pprPP2/7p/1P5Q/2KN4 b - - 0 38 Black played Ba6!! and White resigned. This is better than Rxe4. The main line is Qxh3 (other moves are worse), Bb5! and Black will push the b/c pawns, with a winning attack. But it is a very complex position. --Jon Rookie gets its fail hi...

Re: icsDrone

I'll check it out. Docs seem to indicate it is for FICS and near derivatives only: "chessclub.com - some features may work, others surely does not" --Jon Icsdroneng works ok on HGM's ICS. I have used it before in the blitz events. Only tournament mode on ICC might be tricky: it should work because ...

Re: How about we settle the WCCC argument?

A lot of development is done my many teams in book learning algorithms and book preparation. IMO booking is an essential part of a WCCC. I perceive a lot of dogmatic thinking in the replies to my simple description of how the TCEC tournament became the most successful tournament of the past 2 years...

Re: IWCCC 2012 Changes

Centaurs and hand operated computers are now allowed? I challenge Steve B to enter his best dedicated! I'm tempted to enter my Genius 68030 to play the bye. Someone should enter some cell phones and iPads as well. Does the Hydra supercomputer still exist? That would also be an interesting entrant! ...

Re: Operating System

I know there is a selection biais in asking this question here, but just wondering what fellow chess programmers use I have to say, I'm pleasantly surprised by the result of this poll. There are a lot more Linux users, than people generally imagine. Of course the popouation in this forum is mostly ...
