Re: Draws with Knight odds are possible against a top GM?

In the game chat Leela says the ID is the same Kaufman used 11248. Thanks. I don't suppose Leela mentioned any other UCI settings? I used the ones recommended for 2080 in a talkchess post, plus a small temp setting for the first three moves. I think they must have used a too-high temp setting, sinc...

Re: Draws with Knight odds are possible against a top GM?

but given the zero for ten result I would imagine that the 2500 player at the 45' + 15" time limit would at least have a fairly competitive match at knight odds. Probably a top GM wouldn't give up more than an occasional draw at that level, but let's see how things stand a year or so from now. Yes,...

Re: Draws with Knight odds are possible against a top GM?

I got some solid data bearing on the question. Two days ago I got a new laptop with a 2080 GPU. Although the networks starting with 3,4, or 5 are hopeless when giving knight odds, Lc0 network 11248 has no problem. I have played six games at 5' + 5" against it at knight odds, alternating b1 and g1 kn...

Re: Draws with Knight odds are possible against a top GM?

I think if you wanted to create a network for Lc0 that plays really well at Knight odds is to train it to play without the Knight. I think it will very quickly figure out the best chances in the position and play much stronger than if it was simply playing with a network trained on the normal start...

Re: multi PV mode

Larry, anyone. Halving the cpu resources should cost the typical engine somewhere around 20(?) elo? Yet MPV =2 kills ~100 points. Why is the MPV performance hit so high? (A simple question with - I suspect - a complex answer! :roll: ) Well, 20 elo for a doubling might be close for 3 hour games on 4...

Re: Draws with Knight odds are possible against a top GM?

Very interesting as always Kai! Some comments: 1. I think Lc0 is better at giving handicaps than Stockfish or Komodo, provided that the network choice and handicap show a win prob. of 3% or more. Network 11248 is great at giving knight odds because it shows a win prob. of around 13%. Ridiculous, but...

Re: multi PV mode

For all normal engines, multiPV hurts the strength more than "slightly". Some tests I ran indicate that looking at just two moves costs normal Komodo about a hundred elo, and looking at four about another hundred elo. Stockfish may not lose quite as much, but still a huge amount. Lc0 and Komodo MCTS...

Re: Today is the day.

the emergence is complete … block box wins over knowledge … I see it as unbiased knowledge wins over biased knowledge. I see it as 2000 cores wins over 16. But having said that, I must admit that I am happy to see Lc0 surpass Stockfish, because Lc0 does play more human style chess than Stockfish, a...

Re: Knight equals 48 pawns?

You were quite correct, except for the "little bit more robust" comment; the difference is day and night. With the 11248 network the win probs are all much closer to 50%, so knight odds gets 13% instead of 1%! Of course 13% for knight odds is ridiculous, but the result is that it plays quite well gi...
