Re: A little improvement to the Texel's tuning method

Rhetoric 1.4.1 x64 4CPU

Re: FCT1 / SWCR: New record ... mate in 21!

12) ... b5?? was the howler. All engines say 12)...0-0 instead and white has slight advantage but black is still good. I haven't analyzed the game, but it looks like a horizont effect due to the forward pruning. I have seen other positions where rhetoric suffers from this effect, and also Stockfish...

Then, 22% it's Ok! You must have a good eye to detect that ro thhetoric is weak in endgames, or the transition te endgame. You will be surprised by the amount of code dedicated to endgames...
