Congrats to Ed for improving Kingsrow. Krzysztof, can you try with Scan setting book margin 0? I suggest 988 games, 1 minute/game, 8 threads.

Match SJENDE BLYN - KINGSROW (2-move ballots)

Postponed to another date.

Have you set a new date for this match yet?

I will play such a match.I will make an option book margin 0. So far, the match lasts 3 minutes and 5 minutes. As for the match, I'm not sure if it will take place, because I'm preparing for the tournament "Unofficial World Championships Of Computer Programs Rapid 2020".

Can you give the date until which programmers can send you software updates?

IMO the best way to run these engine vs. engine matches (not Krzysztof's tournament) is with Tmgr. With one command you can run as many parallel matches as you have cores, play any number of games, get consistent time control, adjudication with an 8-piece db regardless of the egdb the engines are using, and complete summary of stats and game pdn files. For example, here is the summary of a match of over 15K games played at 75 moves/1 min. It took about 30 hours to play this match on a 16-core Xeon W-3245 @ 3.2 GHz.

The tournament will take place on September 1, 2020. The tournament page and tournament results page are ready. This information is not yet publicly available yet. I wrote to Bert if he has time, he can make a book for his draughts engine. Jelle also probably write a new version of the program Sjende Blyn.

Ed play through dxp. Don't play through Tmgr. You'll only see differences in results.
