I thought to find how much speed improvement I can get by pawn hash tables for part of the evaluation that depedenent only on pawn structure but I find that it is not so simple. The problem is that I have opening evaluation and endgame evaluation and I calculate average of them for every pawn based ...

your results are good. In 6 games everything can happen. In my opinion more amazing is the 9.5:0.5 that the default version got against fruit2.0 in the first 10 games only to lose 9.5:0.5 in the last 10 games of the match. Thanks for your testing I admit that I did not test 4 6 10 Here are some resu...

GM's are far too good to need to set traps, that's an insult to all GM's! This really shows the lack of understandin...

I wish I could present a nice combination by Glaurung 2, but although my new engine wins more games than it loses against its older brother, it always wins in ugly and boring ways. The position given below, therefore, is from one of the games were Glaurung 1.2.1 won against the new Glaurung: [D]rq1...

I use to play OTB and finished with 1798 USCF. In looking at this hard position, I am extremely impressed with the play of white. I wonder that the expert (black) actually felt good about the position and was wondering if to accept a draw or press for the full point. Very nice position and move, es...

Well, I explicitly inquired if the rules allowed it. It seems they do as long as it are totally unrelated programs, as uMax and Joker are. Unfortunately 2 times 0 is still 0. It seems all other contestants have at least 400 rating points more as the last measured rating of my engines. I think that ...

40 games Movei scored 24.5 simple math tells me that petir scored 15.5 and also if you count the points you can find that it scored 15.5 I think that the difference is small and the number of games that were played are not enough to get a conclusion about which version is best. I played more games ...
