Slight modification over 2r1bk2/pp4pp/1nn5/8/4P3/2N2P2/PP1R2PP/3R2K1 w - - 0 1 | That is presumably winning for white

[d]2r1bk2/pp3pp1/1nn5/8/4P3/2N2P2/PP1R2PP/3R2K1 w - - 0 1

Long TC game with decent hardware in case on Leela vs Stockfish and vice versa will be appreciated.

Not exactly long TC.

Guess it's lost, yet Black could set up some more fight than in your game.

LC0 was 2xRTX 2080Ti net 49921, SF (Moonfish Jörg Oster) 24 threads of 12x3GHz 8 G hash, 60'+15". 6men Syzygys.

Hi Peter!

I plan to purchase another RTX 2080 Super on Black Friday.

This endgame occured in a 5+5 blitz game between Fat Fritz RTX and SF 10 (default contempt)

What is the analysis. I manually adjudicated it as draw because the eval was stuck on +2 / 2.5. It might be winning with deep analysis.

Yes, probably.

To say it in a Tsvetkovesque way: about 60 moves to mate.

Not because of the output- line, that was just the length of a quick playout with SF (Moonfish) only.

Lc0 is capable of beating SF Dev here as white.
