You think that this will be an easy draw for a GM? I don't think so man... this isn't Magnus that he will be playing here.Jhoravi wrote:Easy draw for the GM but very difficult to win.

Re: What will Komodo score giving two pawns to GM?
I just played a game against Larry's 24-core machine at f2/c2 odds to see the broadcast was working. In a 2 minuet blitz game I lasted 40 moves. Komodo equalized at move 15 and was better by move 19 and the game was all but over by move 23.

Re: What will Komodo score giving two pawns to GM?
I played 3 blitz (5m+3s) against Amadan (a quite strong player in blitz/bullet, 2150 FIDE) on Lichess : 3-0
I set Komodo to 2min+2sec, manual operation to copy moves.

Re: What will Komodo score giving two pawns to GM?
My guess is it will be close, with many draws, say 3-4 draws out of 6. In self-play, Komodo needs 1/100 time odds to make for handicap at this time control on one core, meaning 600 ELO points. The estimated value of the handicap increases first in self play, second, with time control, from 400 points at ultra-fast to 600 points at 45'+15''. If Komodo on a strong hardware is reasonably assumed to be 3200 FIDE ELO rating, that would mean a Komodo performance with c2 and f2 pawns handicap to be around 2600 FIDE ELO, a bit higher than the opponent's 2500. I would choose a range 2.5-3.5 points for Komodo in this match, but I voted for 3.5 because it seems I am the only one predicting that score .

Re: What will Komodo score giving two pawns to GM?
I played 100 games between latest Komodo versions with one giving the other the two pawn handicap. Four threads, 2' + 1". White won one game, six draws, 93 losses. +552 elo for Black. This would of course increase with longer time control. So my estimate of the rating value at this tc is at least 700 elo without even considering that White can modify his strategy for the handicap. Not too far from your estimate. I'm a bit concerned that it seems that there is pretty much only one reasonable way for White to play the opening, and therefore he will be able to prepare effectively and/or learn from each game. Because of this, I'll be happy with a drawn match.Laskos wrote:My guess is it will be close, with many draws, say 3-4 draws out of 6.

Re: What will Komodo score giving two pawns to GM?
That an opening book was necessary and that the black advantage of c2 and f2 handicap is too much positional too, besides material. The computer in self-play doesn't learn an overwhelming opening with forced exchanges. My guess is that varied 2 pawns handicap, not c2 and f2, with an opening book, can stand against a 2500 ELO human in 6 games. But I might well be wrong again, who knows what these GMs are up to .duncan wrote:anything you would lime to add now that the results are in.?Laskos wrote:My guess is it will be close, with many draws, say 3-4 draws out of 6.

Re: What will Komodo score giving two pawns to GM?
Every GM I talked with about a 2-pawn handicap said, after a few seconds thought, "Two pawns, that's a lot." They didn't need clarification about which two pawns to make their assessment. They didn't care what program, or hardware, they'd be playing against. They didn't want a copy of the program to practice against.Laskos wrote:...My guess is that varied 2 pawns handicap, not c2 and f2, with an opening book, can stand against a 2500 ELO human in 6 games.

The final match score at two pawns was 1 out of 5. So 90% of you miscalculated something every GM agreed upon, two pawns is a lot.
For an interesting match we should defer to GM's to figure out interesting odds, not engine fans.
