Re: PST-only Evaluation for MinimalChess 0.4

I doubt if everyone who use Pesto to replace their own tuned values sees a significant elo gain. I do not know about the values of Dumber but I believe that TSCP has not tuned values for piece square tables otherwise they could make knight and bishop equal more than rook and a pawn. Dumb/Dumber eva...

Re: PST-only Evaluation for MinimalChess 0.4

What is the ccrl rating of the strongest engine that uses PeSTO? RomiChess is a "minimal" chess engine. Well, afaik that would be the original PeSTO which plays at 3100 ELO! So the question becomes what is to be considered minimal and what is to be considered incomplete. I don't think an engine pla...

Didn't we already reach #2 when Alpha Zero taught itself to play?
Not exactly because using ideas of humans together with using alphazero's method is still better than using only alphazero's method.


Stockfish still test patches written by humans in order to get better and I think same for lc0.

Re: Knight odds test blitz match dragon vs GM Lenderman

I can add that without demotion it is better to resign if you see that you do not win even if you can probably still draw because you do not want to lose time. I can also add that the best strategy for dragon to prevent the GM to earn money is never to resign and to use almost all the time that it h...

Re: Knight odds test blitz match dragon vs GM Lenderman

I think that it may be interesing if there is not only promotion if you win but also demotion if you lose and of course for promotion you do not win money unless you promote to level that you were not in it earlier so if you demote from 9+1 to 10+1 you need to win 2 games without losses to get more ...

Re: Draw by 3 fold repetition...

Because SF prefers 0.00 over -0.01. How it chooses between 2 0.00 moves? First come, first served. An alpha-beta search does not even get to know that the second move is 0.00 and not <0.00. Depends on the implementation Not when it implements alpha-beta. I recall Rebel Decade used to be able to swi...
