Re: Cheating in Let's Check

Cheating in Let's Check Compile a Stockfish that adds 5...10 to the depths it outputs. Also add some minutes to the search times it outputs. Maybe such ideas are helpful to improve Let's Check in next update ? Any idea if it is allowable for example to use 2 computers, and login with same account a...

Re: Problem with Bihasa

Thanks for this info. I can see now where the problem is, this can occur when a fen set-up is used :x , the TC type was changed when receiving positions from setboard . I have not encountered this since I do my testing from pgn files. I will fix this including those additional comments.

Re: About been aggresive as a point machine

Do you think, or have you noted, or do you have testing data that make the saying "best defense is an attack" true?. I mean, do you think doing a aggressive engine is more paying? I know that current engines see "nearly all" and this could be a philosophical question, but I feel interest on opinion...

Re: Fritz 13: “Let’s Check”

Is there mini-max support? How it differs with IDEA of Aquarium?
We may solve the opening with this idea :), the more contributors the better, opening preparation will be a bit easier then.

Re: PGN Extract

Has anyone ever coded an interface for PGN extract? I think this would be an extremely useful tool. I understand that a lot of you do not mind using a command line but it is extremely painful for me. I understand that this would be a non-trivial task but never the less it would save me lots of time...

Re: Over-aggressive pruning

I wonder if it would be beneficial to prune extremely aggressively followed by a verification using a more conservative but lower depth search. Today's top engines are undoubtedly the strongest any engine has ever been; however, I have seen many individual positions where any one of the top 5 has p...

Re: pre-announcement: 10x8 tourney

Very interesting game between Bihasa and Joker80, where the chances turned several times, until Bihasa finally won: Bihasa gets material advantage but its king was forced to go to center, after which it was Jokers' time to go for a win. On move 49 Bihasa is at +12.70, Nebiyu is comparatively unworr...
