Leele satisfies with a slow RAM - what is effective the page file sys - so if set for your PC a big page file sys on your HDD even it will be appropriate for Leela.
But will setting a big page file sys make Leela destroy your hard drive?

Re: CEGT - rating lists March 29th 2020

It is a tricky issue. In CCRL we currently treat the GTX1050 and below as single CPU, and the RTX2080 as multiple CPU. I'm not sure there is a right or wrong answer. In reality the GTX1050 is probably in between 1 and 2CPU. But is the CPU version of Leela on the list? That obviously can be single C...

Re: An idea for a different type of tournament

Don't expect SF 11 to find shortest mate in 2 posted positions. It can't even find mate in 11 :oops: 3qk3/8/8/8/8/8/PPPPPPPP/RNBQKBNR w KQ - 0 1 What engine gives you mate in 11??

Re: testposition from the topboard of the candidates

Stockfish give +7 for white after 33.Rb7 FEN: 6r1/pR1nk3/4p2p/3pPp1N/q1pP1P1p/2P5/6P1/1Q4K1 b - - 1 33 Till now it looks like that 26...g6 is no improvement for the defence against 23.f4 ! Maybe you can impove the defence? Check the black moves given by Lc0 in the posting of zullil. If you didn´t f...

Re: When will the chess programmers write an engine that plans ?

Yes, Fritz sparring features fall well short of expectations. I would like to take another look at MB's Weakfish with reduced strength settings. That reminds me of something. There were tests that only a couple of decades ago were done with pen and paper for a few hours. Then the educational bodies...

Re: testposition from the topboard of the candidates

We do have Carlsen's opinion. We also have access to Leela's (and Leela has superior performance to A0).

What was it that convinced you this move was so great?
