Is there any information on how come Junior doesn't compete this year?

It is actually not so negligible. Take a two core box. You run A vs B, no ponder, both using 2 cores. They don't interfere with each other, both get 200% of normal compute time per move. Pretty good win. Now run A vs B, both pondering, both using 1 core. When it is A's move, it burns 100% of a CPU,...

These days every ordinary computer or notebook has more than one CPU, mine has two e.g. I read on this board that given you have to decide between providing more CPUs to engines you pit against each other on a single computer for testing purposes with ponder off and less CPUs with ponder on you'd ra...

Which goes to show that people should better play it slow before giving some private event "official status".

ICGA events may leave a lot of things to be desired, but they place responsbility where it is due, namely to the competitors.

Hi, I have questions from a total novice point of view : a) I red that the best .exe is the one compiled by youself for your own computer. Is it right ? . That's kind of like saying that the best chair is one that you make yourself specifically for your dimensions. For a skilled carpenter it would ...

When it is about chessengines the discussion has already turned out to be moot years ago. When you outsearch someone like mad you are usually supposed to be a great positional player. It is great fun to look back at the engines that were once supposed to do great strategically and compair to the imp...

If there are a lot of losses in a single variation for nobook, this can lead to wrong impressions on book value though. I'd like to show a counter example where nobook looks pretty smart to me: r1bqnrk1/1pp2pb1/3p2pp/p1nPp3/2P1P3/P1N1B2P/1P1N1PP1/R2QKB1R w KQ - 0 12 Stockfish nobook played 12. g4 he...

Simplified claim: Opening books are pretty useless these days. E.g. Stockfish don't need no book at slow time controls. I almost agree with you. However, to measure the book effect per se, one needs to depollute the measure from the time biais. ... Generally, the larger the book, the crappier it is...

[quote="Laskos] I once went from game in 1'+1'' on one core to game in 5'+3'' on 4 cores, and although differences between books get a bit smaller, it's due as usual to increasing draw rate. One has to keep in mind that books are not simply successions of positions analyzed by engines, and it doesn'...

<snipped> I disagree and if you build opening book correctly the book can be useful also in 3 minutes per move. I have no idea how people build opening book but the logical way to do it is simply to give program like stockfish or komodo a lot of time in every position that you want to add to the bo...
