Problem to Lc0....

[d]rnbQKbnr/pppppppp/8/8/8/8/PPPPPPPP/RNBqkBNR w - - 0 1

In this position Stockfish found mate in 12... 1.Nc3

Friends can collaborate with some Analisys with Big GPUs . Thanks!!!

Lc0 really doesn't do well on positions that is has no chance of ever having seen anything remotely like it, so it will probably have much more trouble than Stockfish. It's not even a possible chess position, and Lc0 only trains on chess games.

Lc0 (network 320x24.J13-swa-410000) 100M nodes:

info depth 8 seldepth 50 time 819885 nodes 100000035 score cp 12800 hashfull 32 nps 121968 tbhits 0 multipv 1 pv b1c3 d1c2 d2d3 e1f1 c1e3 f1g2 g1f3 g2h3 a1g1 g8f6 e8f7 c2b3 a2b3 f6h5 d8c8 b8c6 c8d7 e7e6 d7e6

Is 12800 a mate score?

[hammerklavier]

Is a strange position... Valentin Albillo presents this position in your page (2003 aprox) ...

Stockfish see mate in 12 in few seconds. But really not understand why Lc0 not....

In the past this problem was a nightmare for the majority of engines , but in 2019 with networks engines...

Thanks for your GPU time & Analisys!

I don't understand why (and how) stockfish is solving this so quickly.
This position seems quite hard for Minic that sees something at depth 27 and then takes a looooooong to get it right.

Showcasing FabChessSMP 4cores, needs some time to solve the mate, found NC3 fairly quickly though
