I guess that Komodo Dragon can only beat a GM rated over 2500 with TC of 10'+5". Is this the MCTS or standard Komodo Dragon playing and how many threads ? Ask him to play 2 extra games at TC of 10'+5"

Actually Komodo Dragon performed very good for him having the latest commercial version to practice against, next time play at this TC of 10'+5"

Re: Komodo Dragon vs. GM Perelshteyn, knight odds match.
So the final score was 4 to 2 in favor of GM Perelshteyn, exactly the same ratio as in our previous match with the similarly rated GM Wirig (we lost 6 to 3, same conditions), and half a point worse for Dragon than my prediction. This time we won one (the last game), lost three, and drew two. One difference from the previous match was that Komodo played as if it were blitz (5 sec/move average). We used MCTS for the first three games (using all but one of the 32 cores), but only scored half a point, and lost the third game quite badly. So at the halfway break I switched to standard mode, and we did better (one draw, one loss, one win). Of course the sample size is too small to say anything with confidence, but I felt that Dragon played better in standard mode under these conditions. Perelshteyn played quite well, making no obvious blunders; in all previous knight odds matches, the human GM or IM or FM made at least one obvious blunder. Dragon at least avoided losing the majority of the games, making this the third knight odds match (including IM Toth) in a row in which Dragon has accomplished this feat. But it is apparently not yet strong enough to win or even draw a knight odds Rapid match against a 2500 GM; it can often save draws in bad endgames, but winning is very difficult at knight odds.
I also note that Dragon scored only 0.5 out of 3 with b1 knight odds, but 1.5 out of 3 with g1 knight odds. Here too the sample size is too tiny to say much, but my subjective opinion is that Dragon gets better positions with g1 odds than with b1 odds, primarily because 1.e4 and 1.c4 are both good move at g1 odds but poor moves at b1 odds. For the future, we could just do g1 odds (it is the odds-giver's choice normally of which knight to remove), but there is something to be said for variety. Or we could change the ratio of g1 to b1 odds games.
Games can be viewed or downloaded by going to chess.com archives and looking at the latest games of PlayKomodo (or EugenePerelshteyn).
I remain convinced that the goal of defeating a 2500 FIDE GM in a Rapid knight odds match is a realistic goal for the next year, but we'll need to find ways to pose more problems than we do now.

Re: Komodo Dragon vs. GM Perelshteyn, knight odds match.
Here is the 6th game as it was played up to the 7th move[/size] This is a good way to find out if the human GM indeed plays better than Gaviota 0.84 win 32 with Knight Odds and the other 5 games can also be replaced with Gaviota 0.84 win 32 after the first 7 opening moves, by doing this we can figure out if the opening choice of moves was what caused Dragon 2.5.1.x to lose the Match, or is it that the GM is much stronger than Gaviota 0.84 win 32. I suppose that selecting very aggressive Opening scare human GMs, and therefore, the contempt should be lower a little bit to make it more aggressive, remember if all the pieces and pawns are exchanged with the extra knight the human can only get a draw

Note: I just finished with my little experiment the conclusion is that a GM like Perelsteyn rated 2509 play better than any engine rated similar by CCRL at Knight Odds Vs Komodo Dragon regardless of the contempt settings either =100 or 75

Experiment #3 For this game I took one of the game played yesterday up to move 7. 0-0
Bg4. I set it up to Contempt = 100 much defensive than for contempt = 65. You will notice that move 11. h3 is one of the defensive move made here. I used the standard mode NOT MCTS.

Bg4 I set it up to Contempt = 65 much aggressive than for contempt = 100. You will notice that 11. Nh4 is one of the aggressive move made here. I used the standard mode NOT MCTS. I read long time ago that Mike Tyson trainer once told him when he started boxing you do not win a fight by holding back and wait for your opponent to start attacking you with punches, you have to be the first to scare your opponent with your punches and beat him to death.
