Re: top engines vs 2400 engine knight odds matches

You can try this with Stoofvlees as well (you should have a copy). I expect it to do even better than lc0. I've been too busy to check it out, but since you made this comment I'm motivated to check it out next week when I should have time. Is this the chess analog of the Leela Go situation where th...

Re: UCI_Elo

Any advice to tune engine parameters to correspond to the right UCI_Elo value ? In Cheese I have 2 parameters, one to make very small pauses every N nodes, and another one to add randomness to the evaluation under 2000 ELO. If we cannot find a reference engine and corresponding UCI_Elo value we mig...

Re: Draws are getting cheaper, are 15W enough?

Does anyone run correspondence or freestyle events with rules designed to avoid or minimize draws, such as specified one-sided openings or startpositions, or modifications of the normal draw rules, or anything else? Yes, Russian website crazy-chess.ru did this on 2017, they managed to find position...

Re: Draws are getting cheaper, are 15W enough?

I would prefer that the total score given for the game always be 1 point, for several reasons. So I would say that for repetitions without check the side repeating the position for the third time gets less than half point, the other gets more, same as for fifty move rule. That's more neat, although...

Re: CEGT - 40/4 rating list September 9th 2019

Until now + 28 after 1200 games @ CEGT 40/4 + ... Looks pretty good ! Best wishes, G.S. (CEGT team) Thanks. The CCRL numbers for normal Komodo 13.1 came out pretty good, so overall (combining MCTS and regular, CEGT + CCRL + FastGM), I think our +20 estimate for the faster time controls was pretty a...

Re: Draws are getting cheaper, are 15W enough?

Stalemate is too rare for that rule to do much, although of course it will change some basic endgames. Much more significant is addressing bare king (making king and minor vs king a win), and doing something about repetitions, at the very least those due to perpetual check should be either banned o...

Re: top engines vs 2400 engine knight odds matches

Can you tell me how KMCTS works at ultra long time control? What happens when the MCTS hash is full? big In timed play it should just go ahead and move when MCTS hash is full. In infinite analysis mode it will just stop changing anything, waiting for the user to do something. The default is enough ...
