Re: Shogi Perft numbers

I've never concerned myself with perft in my game programs before, but is it supposed to detect checkmates in order to avoid playing past fools mates? I was wondering if perft 7 could be used to enumerate all the shortest mates in shogi. There are 29 mate positions at depth 7 : nodes = 15 086 269 6...

Re: We lost our Pal

I remember being impressed that an engine "discovered" the Benko Gambit in one of the bookless or 4-ply book TCEC sections, but I can't for the life of me remember which season and section that was. If anyone has the TCEC archives downloaded, I'd be grateful for a reminder.

Re: Komodo vs. Larry K on chess.com

I have some chances. Look for games of "playkomodo" vs " Hissha " (that's me). Thanks for your valiant effort! Your handle (Shogi rook) reminded me that you are also likely one of the more knowledgeable folks on the recent strength improvements in computer shogi. When do you think the shogi program...

Re: Congrats the Komodo Team

I don't think the biggest share of the success goes to 8 x Intel (R) Xeon(R) Platinum 8168 CPU @ 2.7 GHz, 128 cores. Because Jonny plays with 1200 cores (60 x 20 cores Intel Xeon E5-2630 @ 2.4 Ghz) but it has only 4.5 points at 9 game. Thanks for those details. Are the platforms for the other four ...

Re: WCCC 2019 Macau..

Well, I think I might agree with Ovyron, which is scary by itself. Why not require that each team must create a robot to act as its operator? Seems more in the spirit of a computer chess event than relying on some specially trained human operator. This event seems like it belongs in another era ......

Re: WCCC 2019 Macau..

The only thing I'm critiquing is the name "world champion", for something clearly not the best in the world, not by far. Specially as people that don't know about this would believe the computer chess world champion is like world champions in other disciplines, so they'll be misled into thinking th...

Re: Ferret 1.00 v258 - program from 1995

I was a big fan of Ferret back in the early days of computer chess. Even further back, I directed chess tournaments in the northwest US. As I was cataloging my games a few years ago I was surprised to see a familiar name: I apparently played Bruce in a "bye game" at a tournament I directed, long bef...

Re: WCCC vs TCEC Chess Engine Competitions..

WCCC has been on a steady decline since 2000 and has been historically irrelevant since 2010 with the expulsion of Rybka. The rating lists have been a far more reliable and inclusive measure of progress since 2005. And TCEC should be applauded for including the full range of top engines, with only a...
