Leela needs a contempt factor: she should not have allowed this draw!

I suspect that there is some bug because in the next game even part of the old engines do not allow repetition and leela also allowed a fast repetition. I will post that game in the next post

[Uri Blass]

game 16 again Leela allowed a fast repetition.

last iteration by some engine with no NN suggest different moves than 24.Rh1 that is a repetition but not third repetition because the opponent does not have to repeat and can play 24..Na6

[Uri Blass]

Larry Kaufman explained about the last draw:

"remember it is using a mixed knight odds and rook odds net, so it may still take a draw if down between knight and rook"

Note that it is not iclear if it is llogical decision to allow repetition when the advantage is between a knight and a rook because otherwise it is possible that Leela is going to play some worse move to avoid repetition against a strong player when the strong player even did not mean to make a repetition and the weak move may help the strong player to win.

[Uri Blass]

Tיhe explanation of larry is simply that the net fror the rookOdds bot and the knight odd bots is the same in the last year and improvement in the LeelaRookOdds and LeelaKnightOdds were only in the search
