What will be the score of knight odds match vs. FM Bolzoni?

[Nathanael Russell]

Since Komodo will most likely unwaver from draws to possible wins and having the tactical advantage despite the lost b1 knight in a white piece game , I will expect in no order out of 6 games:

W/D/L
Komodo: 5/0/1

I would believe 4/0/2 foreseeable but once FM losses a pics for nothing, I don't think he can / will crunch for equality. Therefore resigning a game.

I agree that if the FM blunders a piece for nothing he will probably lose the game, but why would you expect him to blunder a piece almost every game? 2200 rated players rarely blunder pieces against me in tournaments!

Latest Komodo (with contempt to avoid needless exchanges) on fast six core vs. FM Bolzoni (FIDE 2187, born 1962), Komodo giving knight (b1) odds but always getting White and winning draws. Time limit 45' + 15". The only similar match on record was Rybka (near Rybka 3, on octal machine about 8 years ago) against FM John Meyer, won by Meyer with a perfect 4 out of 4 score. Without making any prediction about the match myself, I'll just make the comment that IF Komodo manages to draw or win the match, I think it would be a remarkable achievement. Masters normally just resign when they lose a piece for nothing, or even sometimes if they get a pawn for it. If Komodo pulls off a drawn or better result, it would mean that chess is a much deeper and more difficult game than is generally believed. So even if I had no involvement with Komodo, I would root for it just for what it would tell us about how far human play is from what is possible.

what was John Meyer FIDE score ?

also what would you expect to be the result if a 2800 gm played FM Bolzoni with such terms ?

lets say komodo won. then you beat it with 15' + 5", would it still mean that chess is a much deeper and more difficult game than is generally believed.?

I believe you have misunderstood my previous statement, and I am sorry about that. It is unfortunate. I was intending that the FM would "perhaps" blunder a piece in a "single" game theoretically causing a greater chance of loss therefore adding a loss to the scoreboard. I would "forecast" that the FM would at least lose 4 games against your engine, but that is only a theoretical statement as I nor anyone else can predict the outcome. The FM will most likey win 2 somewhere along the line, but theoretically a blunder in a "single" game could effect the outcome of a possible win.

In my defence, I do not think at anytime I hinted that the FM would lose "every" game due to human error. I have to much respect for a chess master including yourself.

Meyer was 2284 FIDE at the time, which was probably an accurate figure as he was fairly active in the preceding year. We may yet have another match like this with Meyer, depending on how this one goes. I don't think any top player would play Bolzoni at knight odds (same conditions) if he had to win the match to get paid. Maybe he would lose 5 to win I guess, but there is zero data to go by. In blitz I think a 2800 can give a 2200 knight odds with decent results, but this is far from blitz.

Anyone with a 2187 ELO rating is definitely a strong player, but that is not a great rating for a Fide Master. I am pretty sure that what occurred with Rybka will obviously not be replicated for this match. We are talking about a human brain hundreds of ELO below our best humans versus a machine, and modern engine that effectively far exceeds 2700 ELO levels. The abilities, skill, and what the engine sees in its search is a thing of prolific genius compared to a strong player. I find it very difficult to believe that Bolzoni would win even one match despite being a full knight ahead. I would not be surprised at all. I hope that you do not allow the engine to resign too quickly if Bolzoni manages a won position. He could still very likely blunder the game or not see the win.

I personally think that handicap matches take away from the game of chess. That said, I like your point, Larry, that if Komodo can manage to win this match series it will show just how imperfect human play is. Certainly this is an interesting but true point.

By the way, what CPU are you using (a six core yes, but which one)? How much RAM? Are table bases included? How deep will the opening book go?

Hardware detaiils were posted separately. - The computer is an I7-4930K - 6 cores at 4.4 GHz, 8 GB hashtbales, syzygy 4-5-6 pieces.

There is of course no standard opening book for knight odds. I could write one (again, as I did 8 years ago) but don't have the time for that. So the "book" will just be my selection of the opening move for White in each game, so as to have some variety and avoid repeat openings. As for the result, opinion so far is evenly split between a Komodo match win and a match loss. I'm personally predicting a 2 to 4 defeat for Komodo. A piece is a lot! My own experience at knight odds is that I can usually only draw at blitz, but I think I could win this match with 15' + 5", and Bolzoni will have three times as much time as that to compensate for his 120 or so lower elo. If we lose we'll probably use my 24 core for the next knight-odds match, though that may not help much.

I let play Komodo against a stable UCI engine BikJUmp 2.01 (about 2130 ELO CCRL 40/40) at 45'+15'', and knight odds seems quite on spot for this 1100 ELO points difference between engines. 4 games on one core from different opening positions, no adjudications.

Komodo scored 2 wins, 1 draw and 1 loss, or achieved 3/4 if draws are equal to wins. Maybe Ferdinand can analyze the PGN files to see what blunders or inaccuracies BikJump made to lose or to draw. I would guess that BikJump is a bit stronger tactically than a 2180 FM, and if an accumulation of inaccuracies can compensate for the knight, then my earlier prediction of 3/6 or higher for Komodo (with a full point for a draw) seems realistic. Also, if these games of BikJump are of some example for a human FM play, then 6 wins or 6 losses outcomes seem not very plausible.

I let play Komodo against a stable UCI engine BikJUmp 2.01 (about 2130 ELO CCRL 40/40) at 45'+15'', and knight odds seems quite on spot for this 1100 ELO points difference between engines. 4 games on one core from different opening positions, no adjudications.

Komodo scored 2 wins, 1 draw and 1 loss, or achieved 3/4 if draws are equal to wins. Maybe Ferdinand can analyze the PGN files to see what blunders or inaccuracies BikJump made to lose or to draw. I would guess that BikJump is a bit stronger tactically than a 2180 FM, and if an accumulation of inaccuracies can compensate for the knight, then my earlier prediction of 3/6 or higher for Komodo (with a full point for a draw) seems realistic. Also, if these games of BikJump are of some example for a human FM play, then 6 wins or 6 losses outcomes seem not very plausible.

At 1'+0.15'' time control, as expected, Komodo scores even better:
W:40
D:6
L:4

Probably in blitz we can expect Komodo to score 6/6 (with draw=win).

[lkaufman]

Latest Komodo (with contempt to avoid needless exchanges) on fast six core vs. FM Bolzoni (FIDE 2187, born 1962), Komodo giving knight (b1) odds but always getting White and winning draws. Time limit 45' + 15". The only similar match on record was Rybka (near Rybka 3, on octal machine about 8 years ago) against FM John Meyer, won by Meyer with a perfect 4 out of 4 score. Without making any prediction about the match myself, I'll just make the comment that IF Komodo manages to draw or win the match, I think it would be a remarkable achievement. Masters normally just resign when they lose a piece for nothing, or even sometimes if they get a pawn for it. If Komodo pulls off a drawn or better result, it would mean that chess is a much deeper and more difficult game than is generally believed. So even if I had no involvement with Komodo, I would root for it just for what it would tell us about how far human play is from what is possible.

Anyone with a 2187 ELO rating is definitely a strong player, but that is not a great rating for a Fide Master. I am pretty sure that what occurred with Rybka will obviously not be replicated for this match. We are talking about a human brain hundreds of ELO below our best humans versus a machine, and modern engine that effectively far exceeds 2700 ELO levels. The abilities, skill, and what the engine sees in its search is a thing of prolific genius compared to a strong player. I find it very difficult to believe that Bolzoni would win even one match despite being a full knight ahead. I would not be surprised at all. I hope that you do not allow the engine to resign too quickly if Bolzoni manages a won position. He could still very likely blunder the game or not see the win.

I personally think that handicap matches take away from the game of chess. That said, I like your point, Larry, that if Komodo can manage to win this match series it will show just how imperfect human play is. Certainly this is an interesting but true point.

By the way, what CPU are you using (a six core yes, but which one)? How much RAM? Are table bases included? How deep will the opening book go?

Hardware detaiils were posted separately. - The computer is an I7-4930K - 6 cores at 4.4 GHz, 8 GB hashtbales, syzygy 4-5-6 pieces.

There is of course no standard opening book for knight odds. I could write one (again, as I did 8 years ago) but don't have the time for that. So the "book" will just be my selection of the opening move for White in each game, so as to have some variety and avoid repeat openings. As for the result, opinion so far is evenly split between a Komodo match win and a match loss. I'm personally predicting a 2 to 4 defeat for Komodo. A piece is a lot! My own experience at knight odds is that I can usually only draw at blitz, but I think I could win this match with 15' + 5", and Bolzoni will have three times as much time as that to compensate for his 120 or so lower elo. If we lose we'll probably use my 24 core for the next knight-odds match, though that may not help much.

I let play Komodo against a stable UCI engine BikJUmp 2.01 (about 2130 ELO CCRL 40/40) at 45'+15'', and knight odds seems quite on spot for this 1100 ELO points difference between engines. 4 games on one core from different opening positions, no adjudications.

Komodo scored 2 wins, 1 draw and 1 loss, or achieved 3/4 if draws are equal to wins. Maybe Ferdinand can analyze the PGN files to see what blunders or inaccuracies BikJump made to lose or to draw. I would guess that BikJump is a bit stronger tactically than a 2180 FM, and if an accumulation of inaccuracies can compensate for the knight, then my earlier prediction of 3/6 or higher for Komodo (with a full point for a draw) seems realistic. Also, if these games of BikJump are of some example for a human FM play, then 6 wins or 6 losses outcomes seem not very plausible.

The close match you cite at knight odds between Komodo and 2130 engine sounds about right, I would have expected a similar outcome. However there is a huge difference when a human is playing; the human knows to avoid anything unclear since he is up a piece but much weaker player, but I'm sure the engine in question has no such programming, and will readily head for complications to gain one centipawn positional plus. So I think a human must be expected to score MUCH better than a similarly rated engine in such a match.

Legend:
Rank     - ranking based on low average error
AveDepth - average depth reached by the Analyzer in analyzing those positions
AveError - average difference between the analyzer and player score, in centipawn (1p = 100)
DECnt    - count of positions where player move score is below zero and analyzer move score
         - is better than player move score. This is called Dangerous Error Counts
E300CP   - count of positions where player has blundered by 3 or more pawns
E200CP   - count of positions where player has blundered by 2 to 2.99 pawns
E100CP   - count of positions where player has blundered by 1 to 1.99 pawns
E50CP    - count of positions where player has blundered by 0.5 to 0.99 pawn
E20CP    - count of positions where player has blundered by 0.2 to 0.49 pawn
EECnt    - count of positions where player move score is better than analyzer move score

Notes:
1. Analysis of positions start at move 12.
2. If best score of Analyzer is already 6 pawns and above and the score of player move
   is also 6 pawns and above then error for this position is set to zero. The more cases
   like this only proves that that player is able to maintain its advantage and this
   will minimize its average error at the end.
   On the other hand if the best score of Analyzer is already below minus 6 pawns, no further
   analysis will be done, and this position will not be included in error calculation.

I don't have much time to run this at longer time at this time, but I uploaded the tool and epd each round from that pgn. Later I will run this on longer time as I also try to improve the tool.

Estimated max analysis time = analysis time/pos x num_pos x 3. With separated epd by round, and with more cores, this can be analyzed in parallel, just create other folders, copy the tool and epd and run.

Sample run. Just double click the exe file, be sure your engine is in the same dir with the tool. Some files will be generated, the log is in overwrite, but the summary is in append mode. Blunder epd are also saved, and also the sqlite database.

Analyzer error margin is a value in cp used to decide whether to
save the position if player score is better than Analyzer score.
If this margin is low say zero then all positions will be saved.
It is recommended to set this margin to high say 10cp if analysis
time given to the analyzer is low say below 30s. The HW specs,
Analyzer engine strength and its settings could also be a factor.

Someone might be interested to analyze the old match rybka-meyer (at longer time and with more cpu power). Here is the epd in one file. It is better to run this by round so the summary will be separated. There is round in epd file, so it is easy to create r1.epd to r4.epd, then run with the tool. Don't use longer time/pos at first, try it first with say 1s/pos, see if there is problem. I only tested these in short time.
