Quote Navara "At least now I knew I were playing a engine!" :lol:
The first 3 games (1.5 each) were his practice games last week, the actual match score was 7 to 3 for David. He won decisively until dropping the time limit to 3'+1", where he lost 1.5 to 0.5. But he went 4.5 to 1.5 at 3'2", so it looks like the fair time limit is between those two. He scored better with b1 odds (4 to 1) than with g1 odds (3 to 2). Maybe for a future match most or all games need to be g1 odds, b1 looks too easy for the human. David prepared well for the match, he said he reviewed 250 LeelaKnightOdds games. He played quite well, only one real blunder of a piece which didn't even cost him the game, he still drew. Leela seemed to play a bit too "normally", but this may be mostly a consequence of the openings, it rarely got openings with serious attacking chances. The opening book was turned off for the final four games; it's not clear if that helped or hurt. He did much better than pure calculations predicted, perhaps due to his preparation or perhaps it's just that the elo model based on standard chess is not so accurate for predicting results in these odds games.
Does your Dragon has a good chance of drawing against GM Navara Knight Odds at time control of 3'+2" :?:

Anyway I believe it is more interesting to see a match of Rook Odds versus a Master human player

There have already been many games played by LeelaRookOdds on LiChess against masters up thru International Masters. There have been a large number by one rather strong IM, Joan Fluvia (FIDE 2445, was over 2500), mostly at 3' + 5", with the score 29 wins for Leela, 17 wins for Fluvia, and 3 draws. The games are all there to be viewed.

I saw it had been mentioned that GM Sadler could play against Leela without handicap at 1ply. Larry, what would be your prediction on this?

Probably you mean "1 node", since ply is not very meaningful for Leela. Curiously, 1 node Leela is a reasonable match for full strength Leela at knight odds, depending of course on details like which nets and hardware and time limit for Full-strength Leela. So 1 node Leela is roughly of GM level at some reasonably fast level. I would expect 1 node Leela to come out ahead of Sadler in blitz, behind him in classical chess, and maybe even somewhere in the Rapid range.

Meanwhile we concluded that we made a mistake to use the latest BT4 net for the Navara match, as although it is stronger in standard chess than T82 it seems to be weaker at knight odds chess. But we needed the match and other subsequent games by strong players to determine this. We reverted the net for the bot to T82, and since then the LiChess performance has been over 3000 at 3'2" and over 2900 at 5'3". Rook odds performance (playing White) has been over 2700 at 3'2" and over 2600 and 5'3". Even at Queen for Knight odds, performance has been almost 2500 at 3'2". Only with full queen odds do players under 2000 have decent chances.

I wonder what about 2 pawn odds matches similiar to the match kasparov won

https://www.chessgames.com/perl/chess.p ... pid2=15940

What is going to be the performance of Leela against humans in 90+30 time control?

Opinion of other people about the subject:
1)Every player above rating 2000 should be able to win at 90+30 time control against engines without a knight.
When I mentioned the fact that KomodoDragon's performance was better than 2000 the reply was that probably humans can improve their opening and their strategy in a longer match.

2)Computers can improve significantly without a knight because finding the best move and finding the move that gives the best practical chances are different tasks

Well, since Nakamura got crushed 6.5 to 1.5 at 15'10" Rapid by Komodo at two (White) pawns (b2 or c2 plus f2 or g2), and since Rapid is roughly a class below classical in quality, presumably that would only be viable for a top ten GM playing classical. Given the big advantage of the Leela Contempt for odds play, even that might favor the engine now. Two Black pawns would be an intermediate step.

The second point is critical, it's the reason Leela is scoring so well in odds play generally. The Leela Contempt just works very well against humans. I'm sure it can be improved much more in the future. Based on the evidence that classical chess is a class better than Rapid which is another class better than blitz, the current break-even FIDE ratings for LeelaKnightOdds should be about 2700 blitz (3'2"), 2500 Rapid (15'10"), and 2300 classical for a reasonably well prepared, motivated opponent.

Bishop odds is slightly more than knight odds, so presumably Navara would have won more comfortably. But there is no LeelaBishopOdds because bishop odds is not a recognized handicap, having been played only once in recorded history. The only handicaps that have bots are the ones that minimize the difference from normal chess as much as possible given the goal of equilizing chances. Bishop handicap changes the game by making it a strategy to place pawns based on the color of the remaining bishop. Similarly there is no rook h1 handicap as that would eliminate the usual kingside castling, it's always a1 rook. Even queen for knight is always queen for queen's knight as the queen's knight is placed well to exploit the lack of protection of c2. There were no games with two pawn odds in the historical record, but Kasparov made it "standard" by introducing it in his match with Terry Chapman, so we have used that in engine vs GM matches.
