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...

So it's not really clear what is "best', but Nh4 isn't in Lc0's top three. What network did you use? You must have quite a bit of RAM!
Network 42850. 512 GB :)
