Leela QueenForKnight bot

[lkaufman]

There is now a Lichess bot called "LeelaQueenForKnight" which gives queen odds in return for the "b" knight. The default is for the engine to play White, but you can also choose to play White yourself if you need the even larger handicap of queen and move for knight. It is of course much easier to beat than "LeelaKnightOdds", but I expect that in general it will still require an elo starting with a "2" to beat it in a match in blitz. No data yet, we'll see. This handicap was chosen rather than two knights because Leela plays it reasonably well, whereas Leela currently plays two knights handicap very poorly, not sure why. The "b" knight is the right one to remove since it is the one that would quickly exploit the undefended "c" pawn.

I am not sure but I think that 2 knights is a bigger handicap than queen for knight.

I also think the natural handicaps after knight handicap are bishop or rook handicap.

...Leela currently plays two knights handicap very poorly, not sure why.

My opinion: it's in the nature of current NNs to have astonishing gaps in their knowledge that expert humans just wouldn't have, and these occasionally show up and look embarrassing. They are extremely good by historical standards, and I AM grateful - but they have a large number of small pieces of knowledge rather than a deep understanding: as one expert put it, "stochastic parrots".

Yes, 2 knights is a somewhat larger handicap than queen for knight, but when Leela is giving the handicap it is a day and night difference, it basically "resigns" when giving two knights.

Yes, the traditional handicap series went knight, knight and move, rook. Bishop was never given as it changes the game too much, creating a color complex at the start. The reason for jumping to queen for knight handicap was that rook handicap would still be too small for anyone below around IM level to have an even chance against Leela in Rapid (the bot doesn't normally play games slower than Rapid). They wanted a bot that was within range of a substantial number of players. The queen for knight bot seems to be somewhere around the LiChess 2000 rating or so, but it isn't well tuned yet, sometimes it "goes crazy". Whereas the knight odds bot seems to be around 2800 LiChess or 2600 FIDE level in games where base plus increment is in the 7 to 15 range, and in 1' + 1" bullet it appears to be above even Magnus Carlsen's level, scoring 179 to 1 vs a 2558 bullet field!

This may be true, but I don't think that the poor play at two knights handicap is primarily due to NN flaws. The nets do seem to understand that the blunders and other stupid moves I observed at this handicap hurt the eval. I think it is related to MCTS combined with very high Contempt values. MCTS isn't very good (as currently implemented) in situations where one side already has a 99% expected win probability. Contempt is supposed to address this, but it doesn't always solve the problem. There is probably a solution, but not an easy one.

I might be wrong, but since 2 knights is too much of a handicap, I believe that if Leela give Carlsen a Knight and the f7 Pawn it could be an even match , But again it would be hard to get Carlsen or GM Nakamura to play any top engine even with this Odds. I wonder if Komodo or Dragon have a chance of winning against GM Nakamura with this setup

Black knight plus f7 pawn is about the same handicap as rook (a1) odds. Assuming you are talking about 1'+1" bullet games, I think Carlsen or Naka would come out ahead at rook odds, though it might be close. Maybe knight and move odds would be about fair.

Very good point!

From what you've said, evaluation should be amended as follows:

1. If my position is winning, drawing, or slightly losing, play the best move

2. If my position is losing badly, make the position as complicated as possible and make mayhem!

Yes, I had the same idea. Basically, this would be implemented by making Contempt a function of the score (root score, score from a 1 node search, score from some deeper but tiny search from the root, many options here) rather than a constant. I suppose this would work with any engine that had a good Contempt function. The idea can be described as "if we are losing badly, assume that the opponent is a patzer, because if he isn't, we will lose anyway!"

I believe that Dragon already use some of this Idea, it just has to be implemented more precisely as you stated.
