Re: Lc0 with latest test30 nets is vastly superior positionally

b2 b3.JPGAnother position that I suggest to add is this. Very very difficult for a program to find b3 in order to reply on Nc5 with Rb1! and b4 (what does Leela play?) This one Leela with one of the latest test30 nets doesn't solve, it sticks to f2-f3 for at least 20 minutes (40 million nodes). The...

Re: Spectacular incursion of the King

Reviewing the 8th game of Balsa suite of some of my previous tests, I found that the move 8 ... h5 that I think is the best option for Black, had already been played by other versions but unfortunately is no longer played by the most recent versions. Therefore we see that the process of learning has...

Re: Spectacular incursion of the King

It is interesting to note that from another test with Stockfish Dev and same versions of Lc0 32367 and 32467 on 2xGTX 1060, in the 8th position of Balsa test, version 32367 won again with 8...h5 and the pawn sacrifice h4 in the following game, while version 32467 only draw with 8...Ae7. [Event "Lc02...

Re: King Solomon's position, again (Andscacs & Houdini)

Although Black's victory is not as clear as it may seem from the previous game. Game between the same players Stockfish 10 (6 cores i7 4790S)-Lc0 32367 RXT 2070 at 15 minutes plus 3 sec.

Re: Spectacular incursion of the King

75...a4! was another good move by LC0, but it seems SF played quite bad some of the next moves may be also due to time management problems? 4r3/3n4/1p1p4/p2P4/2PQ1p1k/1P2rPqP/P1B1p1P1/2K1R2R w - - 9 75 It seems that Stockfish's failure to play 75. a4 loses the game. I want to mention that Stockfish...

Re: Spectacular incursion of the King

The game was played under Cutechess gui 1.1 that adds "s" after the time. I suspected that because I use cutechess and cutechess-cli too After eliminating all "s" and pasting into Arena, the times are the following After 75...a4 Stockfish has 3:16 left while Lc0 only 2:47, so I think it was not due...

Re: Spectacular incursion of the King

Thanks for the interesting game Javier! I ask myself though, what would have happened if SF wouldn't have 'lost nerves' with 62. Nxf5?! There was no visible progress from 41...Kh4! to 61...Kh4, except that Black looks good of course, but even LC0s score went back to the one 20 moves before. 75...a4...

Spectacular incursion of the King

In the following game from a test, the King of Lc0 made a spectacular incursion into enemy territory, with queen, two rooks and two minor pieces present on the board. The risk of checkmate was diminished by two advanced pawns that caused poor coordination of enemy pieces. The test was done with Bals...
