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 ...

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? It seems that attempts to do something about draws should start with correspondence...

top engines vs 2400 engine knight odds matches

I've been running a series of matches at the (human) World Rapid Championship time limit of 15' + 10" between top engines (running on 7 threads on a 4.9 Ghz 8 core I7 or for Lc0 on an RTX 2080 (with 2 CPU threads) against a single thread engine rated 2415 on the CCRL 40/40 list (Pawny 0.2 64 bit), w...

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: Is e4 significantly better than d4?

I don't know, I still seem to trust more Leela than even Larry. I have zero opening theory knowledge, but I am a bit skeptical when people come with some esoteric to me knowledge, while in the openings Leela already at 1 node is positionally probably GM level. Sorry, I think I will stick with my si...
