Re: LCZero blunders in TCEC cup 4

LC0 doesn't choose Qc6 either for my setup and the score difference is pretty big (0.76).

185GB RAM! How much RAM do you have?
512 GB. I'm working on an NLP project that needs this much RAM. And thanks for posting this LC0 analysis in the proper thread. I think I had some old cookies or something.

Re: No chance

After a deep evaluation, 3.3 billion nodes, LC0's Qf6+ score falls a little. It doesn't see a clear win. It used 185 GB of RAM by this point. +1.31 Qf6+ Bxf6 gxf6+ Kg8 Bd2 Qa5 Bh6 Qxc3 bxc3 b2 Bxf8 Rxf8 Rb1 Rb8 Ng5 h6 Rxh6 Nxa3 Rh7 Be8 Rxb2 Rxb2 Rg7+ Kh8 Bg4 Nc2 Bxe6 fxe6 Ra7 Rb8 Nxe6 Ne3 Kg1 g5 Nxg...

Re: Movsesian vs Kasparov (2000)

As played in the game, LC0 doesn't like 18. Bc1 and 20. Qh2 as the best moves but 21. Qh3 looks like a bigger mistake.

Re: Is this the best Blitz game ever played ?

I looked at some of the moves on 2x Xeon Gold 6154 and 1x Titan V for 10 minutes+ each with 6-piece TBs. LC0 (42850) and Stockfish 10 prefer 11... Nd6 to Bb7. SF -0.27 vs -0.58, LC0 -0.28 vs -0.63. They prefer 12... O-O or Bxc3+ to Qc7. SF -0.86 vs -1.05, LC0 -0.65 vs -1.41 13. Qb3 looks like a mist...

Re: Opening book for game with handicap

I think Lc0 (presumably a current net) is okay for f7 handicap, but it is totally useless for knight odds or more, the analysis is ridiculous (old net like 11248 or 11258 is ok). Interesting. Is the reason you're saying it's ridiculous for b1 handicap is because of a very negative evaluation? That'...

Re: Opening book for game with handicap

Actually I did make such books for those two handicaps a decade ago for Rybka, I think they were available for either the ChessBase or Aquarium Rybka versions (I don't recall which one, or both?) Probably too old to get now. For f7 handicap White should always start 1e4, then 1...e6, 1...d6, 1...Nc...
