Re: question about weak level of engines

I prefer the weak levels to have the following properties: 1)They are not deterministic so humans cannot learn a fixed way to beat them. 2)Their playing strength is fixed and not dependent on hardware or time control. Are there engines with weak levels that have these properties when the levels are...

Re: what is the best engine for big material handicap?

I disagree that it is not chess.

For me it is chess and I would like to rank humans based on their ability in it.

The fact that you need a special purpose engine show a general weakness of chess engines
that are not designed to do the best against humans in the relevant positions.

The 8 pawn games

I wonder if this position is not a dead draw between strong engines at long time control. 4k3/pppppppp/8/8/8/8/PPPPPPPP/4K3 w - - 0 1 I read the following claim in the stockfish group discussion that seems surprising for me. Brainlearn was able to collect most of the fortresses resulting from this p...

Re: CCRL, FIDE and Ratings

The last few months, I have been focused on the UCI_LimitStrength feature , trying to make it more meaningful to the user. Unfortunately, it took me a while to realized that CCRL ratings, as good as they are at the higher end, were very frustrating to work with at the lower levels as they were tota...

Re: No progress for Stockfish in last month

https://nextchessmove.com/dev-builds Weird, because there are many +5 ELO patches! There are not many +5 elo patches. SPRT does not give a good estimate for the elo improvement. Stockfish needs to test with fixed number of games and not with SPRT if they want a good estimate. Unfortunately they wan...

Re: can engines see mate in 999999 in a big board?

You are right.

The king does not need 1000,000 moves to go from rank 1000000 to rank 1 but only 999999 and it was the source of my mistake when I substracted 2 from 1000000.
