Re: What are Stockfish and Komodo estimated rating for these 5 depths ?

Are your students adults, teenagers, or kids? Of all ages, from 4 years old to +60. What is the lowest FIDE-rated student you have who has actually beaten Stockfish at depth 1, and what age? None of them have FIDE-ratings, the ratings I were talking about are just guesses by me, and since I've taug...

Re: What are Stockfish and Komodo estimated rating for these 5 depths ?

I see. I find really strange that the lowest FIDE rating that can be achieved is 1000 and starting people get higher than that already. My students stop dropping pieces after a few games and have no problem getting to a higher level than Stockfish's depth 1, it's surprising 800 elo players at chess...

Re: SFNNue test, 3m + 1s

Thanks for your tests but I see that latest developement versions of stockfish that do not use NN are not in the test. Stockfish developement version is already 25 elo better than stockfish11 based on the last regression tests so the results of 32:20 with 170 draws for LizardFish do not convince me ...

Re: How did this happen? SF says +154 and draw.

Probably Graph History Interaction with the hash table unaware of the 50 move rule. Maybe it is better to start storing the 50 move rule counter in the hash tables to prevent the GHI problem in these cases when the idea is not to do it in every position but only in positions when all pawns or almos...

Re: Zenmastur vs Ovyron No it's not another GROB II!

I never did a serious analysis of the game with engines but
I wonder what is the hard move to find for chess engines that caused some people after some analysis to say that maybe the position after 3...f4 is a draw.

23.f3
Human move (no engine suggested this move.)

23...Rh5
Rh5 is a computer move.
I see no reason for the claim human move.

Stockfish suggested 23....Rh5

Re: Stockfish play very decent giving pawn odds.........

It is certainly a skill, but not one that has much correlation with chess strength. Ha! That's what I've been saying about the starting positions with missing handicap pieces for the engine side all along. "The human drew against the engine after using 10 takebacks to see what it would move and fin...

Re: Stockfish play very decent giving pawn odds.........

Takeback odds with some amount of allowed takebacks are great to fix short-term blunders that the master can understand quickly after seeing the engine reply. It won't fix a long-lasting positional weakness, but it's obvious that takeback odds will noticeably increase the elo performance of any hum...

Re: Stockfish play very decent giving pawn odds.........

My question is if Carlsen need three takeback moves, how many takeback will a master rated player needs at lest 20 or he will need to replay the same game one hundredth time until he draw . Maybe Carlsen needs 20 to draw. Maybe 100 aren't enough. We can't even start to speculate because this terrai...
