Details about Leela Chalange in Jerusalem

game 19
I think Leela gave the human a draw too fast and there was no simple ddrawfor the human in case of moves like 46. Bd5

You are probably right, although the exchange and a pawn advantage with this reduced material is probably more than a knight up at the start, so it isn't surprising. LeelaRookOdds (and LeelaKnightOdds) assume that the opponent is roughly a par (2500) GM playing at a classical time limit.

I asked NM itay sitbon for the reason he accepted a draw with more than 40 minutes on the clock in the first game when he drew against leela.
He could at least think for more time before accepting a repetition.

He explained that he had a cold so could not concentrate and felt that if he is going to continue and try to win he is going to destroy his position
About the second game that he lost he said:
"In the second game, I just wasn't focused from the start, so I wasn't thinking at all. I was too cold to think seriously in two classic games one after the other."
