Re: Only Gary Kasparov can beat the top chess computer? No. Many of us can beat the best machines.

You are right. With some swindli everybody can win against any chess computer. believe me this types of blockade with no breakthrough wont happen in NN engines like Lc0. I have seen Lc0 giving major pieces to SF just to avoid fortress positions. I am waiting for this type of blockade against Lc0 bu...

Re: Bishop stronger than rook ?!

I have seen many Lc0 vs Stockfish games where minor wins, with equal pawns on board. There was also a nice popular study said to have originated at armenia where a lone B defeats a Q. In short, it all depends on position.

Re: Playing the endgame like a boss !!

Sorry but I disagree, I have seen endgames of Lc0 where winning moves can't be reproduced by AB engines because it involves zugzwang at the end of the PV which would win. Ok, but to be fair I have seen very strong tactical combinations of SF too with many mating nets at the end against Lc0, which L...

Re: Playing the endgame like a boss !!

If Kingcrusher thinks "science fiction move" is a compliment, he should think again about what "fiction" means. What he means is some chess moves that are so amazingly incredible that they seem taken out from a science fiction novel. Something that is real but seems unreal because of how unbelievab...

Re: SSD Problem

A setback. Looking for a good disk recovery utility. My 1TB SSD had 300+ GB free, but WinRAR and tar could not expand anything saying it was full. This was under both Win7 and Ubuntu. The disk was Win7 NTFS. It was strange. Got the notion that Win7 disk defrag might help. It ran for 3 days... Thing...

Re: The problem with adjudication based on score

Try this one in your favorite chess engine and you will see the problem immediately (unless some engine scores it zero): 7r/6p1/7P/p1r1p1k1/Pp1pPp2/1PpP1Pp1/2P3P1/K6R w - - Nice study. This is a draw where engine thinks its a win. I have seen even worse where engines thinks the other side is winnin...

Re: Why you need opening book for Stockfish!

I think I have also seen h5 or its transpositions played by top GM's but current engines would punish this move with hairstrand accuracy.
Usually arises in sicilian dragons too. I feel like that h5 of SF10 was previously played too.

Re: SF10 on zugzwang and lost. Engine immortal zugzwang

Very tough positional sacrifice leading to another zugzwang and wins. position arised after 28...Kf7 of black which looks equal but decisive due to zugzwang. [D]5r2/p4k1p/1pb1q1pP/2p1PpQ1/2Pp1P2/3B4/P1P3P1/4R1K1 w - - 3 29 g4! is best move as played in text. This leads to a forced win for white even...
