Re: Is there a difficult EPD file with test positions

What's funny is that almost all alpha-beta engines can't find this Qf6+! move but easy for an NN type.
Even funnier when someone like Lyudmil claimed it will take more than 20 years of
technological advancement before computer engines can solve this types of positions.

Re: Is there a difficult EPD file with test positions

That are difficult even for todays engines ? E.g. if we want to test LC0 or Stockfish versions by a test suite, we would need a stronger test suite because they search Very deep and todays computers are very fast. Please a few difficult New epd Test suites. Thorsten, here are the 48 hardest (for th...

Re: A letter of thanks and gratitude to the scientific community, they describe a door through which tomorrow is glimpse

Thanks for your post. You have chosen the wrong opponent, it should be Lc0 not BlueFish so you can show all of us how you can create fortresses against Lc0. Good game between Lc0 and BlueFish that you posted, it is an unusual perpetual check where more than half of the board is used for the perpetua...

Re: "Fat fritz" stronger than Stockfish ?

This position is a composed chess study. It's very hard for the human eye to solve this because it's a mess. Leela have a hard time here. Stockfish is better here.

Re: Chess Fighter - wins against Stockfish, Fire...

Plays like Lc0. Is this open source?
Good wins with obvious NN style of play.

Would be nice to see most of its games as I am ineterested on game played by NN vs. A/B engines.
Thanks for uploading.

AB vs NN fun games

How SF managed to trap its own dragon B without even realizing it. This is a curious game where SF didn't realize its Bh8 is dead, useless piece. In informator lingo it would be called (xBh8), and its eval score didn't even show that he is already a piece down. [Event "CCC10 Semifinals (10|3)"] [Sit...

Re: The Busted Dutch

Well, I'll go on record saying that latest Stockfish is insane if it really thinks 2.c4 is 0.85. Maybe Larry is right about some weird scaling happening now. For contrast here's private Stockfish with learning up to some depth 33. The thing with this version is that, if 2.d5 is best, I can show it ...

Re: The Busted Dutch

My opinion on this 2.d5 against Dutch is that this move allows black to equalize quickly. Maybe time to call that 2.d5 move Tsvetkov Attack. But seriously, it was not yet played by very strong players in tournament conditions because it is counterintuitive. Reason why 2.d5 wasn't played, it violates...
