analysis of game 4 the order is not based on chronological order and I first give the games of LeelaPieceOdds that played part of the games with rook odds and part with 2 knights odds and later the game of LeelaRookOdds.
There was some technical problem to give LeelaRookOdds too many games so LeelaPieceOdds came to help by playing some rook Odds games.

Re: Details about Leela Chalange in Jerusalem
You gave the venue as Yerushalmi Club, Yohanan Ben Zakkai Street 5, Jerusalem - so why was anyone using a mouse?
When Gary played Deep Blue, he wasn't made to use a mouse.
Human chess is partly about tactics and strategy, but mostly about memory

Re: Details about Leela Chalange in Jerusalem
The players were mostly playing on real boards, but someone had to enter the moves into LiChess, and unlike DeepBlue there was no IBM or comparable sponsor to hire a team of operators, so the players had to do it themselves. So you can think of it as perhaps 90' + 25" per move instead of 30", not a major difference.
Komodo rules!

Re: Details about Leela Chalange in Jerusalem
I have problem in analysis because I do not trust latest stockfish or stockfish17.1 so I use other engines
For example in the following game
https://lichess.org/2iBv6AYg
33...Ne6 is marked as inaccuracy and it is claimed that Qd8 is best but old engines claim that Qc7 or a5 are best and they do not consider Qd8 to be a top move
Who is right?
personally I believe a5 is the best move but the real blunder of black before the losing move was 34...Nxf4 when 34...a5 is still winning when after 34...Nf4 35.c7 black need to sacrifice the queen to get a very complicated win but for some reason thanks to stupid NN that does not know which win is better the move 34...Nf4 is not marked as a blunder in the analysis.
I gave stockfish developement version of 1.12 4 options and analyzed for a long time
It claimes that Qd8,a5,Qc7,Ne6 are winning
scores of alll moves go up and here is the last analysis after one hour of search at depth 32

For example in the following game
https://lichess.org/2iBv6AYg
33...Ne6 is marked as inaccuracy and it is claimed that Qd8 is best but old engines claim that Qc7 or a5 are best and they do not consider Qd8 to be a top move
Who is right?
personally I believe a5 is the best move but the real blunder of black before the losing move was 34...Nxf4 when 34...a5 is still winning when after 34...Nf4 35.c7 black need to sacrifice the queen to get a very complicated win but for some reason thanks to stupid NN that does not know which win is better the move 34...Nf4 is not marked as a blunder in the analysis.
I gave stockfish developement version of 1.12 4 options and analyzed for a long time
It claimes that Qd8,a5,Qc7,Ne6 are winning
scores of alll moves go up and here is the last analysis after one hour of search at depth 32

Seemed as though black was playing very well until the sky fell in!
Human chess is partly about tactics and strategy, but mostly about memory

Re: Details about Leela Chalange in Jerusalem
Last night GM Andrei Deviatkin ("Former_Player") played 63 Rapid (5'5") games with LeelaRookOdds. Leela won 47, drew 13, lost 3, so score was 53.5 to 9.5. Another (higher-rated) GM, Peter Acs, also played 4 games with same conditions, losing 3.5 to 0.5. These results suggest that "par" grandmasters probably need something like 30' + 30" or so to break even with LRO, which is pretty consistent with the IM level result at 90'30" against titled players for LRO in Israel.
Komodo rules!
