RE: danilov' claim that kramniks moves match fritz9, the chess mind has a nice rebuttal

Wow, conclusive proof, right? Not really. First, we'd need to confirm Danailov's claims. Second, we'd have to show that they're really statistically significant. For instance, I've played bullet games (without cheating, in case there are any smart alecks out there) with a higher degree of coincidence with my engine's suggestions than the Kramnik 78% figure. Sometimes the position is such that some move or series of moves is just obviously best (captures, recaptures and forcing variations are the most noticeable examples). Third, were these non-obvious, "non-humanish" moves that mattered? Fourth, did they further coincide with bathroom breaks? Fifth, what's the usual degree of coincidence between Fritz 9 and Kramnik's chess, especially when playing Topalov? Sixth, what about other super-GMs? Do they generate roughly similar coincidence numbers?

After very detailed analyze of all games of the match we would like to present to your attention coincidence statistics of the moves of GM Kramnik with recommendations of chess program Fritz 9.
First game:
From 75 moves: After the 12th move of Topalov Ba6, a novelty, from 65 remaining moves – 41 moves match with the first line of Fritz 9. (63% of matches)
Second game:
From 63 moves: After 17th move, where the theory ends, from remaining 46 moves – 40 moves match with the first line of Fritz 9. (87% of matches)
Third game
From 38 moves: after 10th move, when the theory ends, from 46 remaining moves – 40 match with the first line of Fritz 9. (86% of matches)
Forth game:
From 54 moves: After 14th move, when the theory ends, from 40 remaining moves – 30 match with the first line of Fritz 9. (75% of matches)
Sixth game:
From 31 moves: After 13th move, when the theory ends, from 18 remaining moves – 14 match with the first line of Fritz9. (78% of matches)
Thus, out of 5 games – 78% of GM Kramnik’s moves match with the first line of Fritz9.
Sincerely
Silvio Danailov

Seems like the % Kramnik is cheating is above 63%.
Originally posted by Los AngelesI've analyzed hundreds of GM games with Fritz, and 75% agreement seems below average. Many patzers (myself included) often achieve 50-65% agreement. The conclusion is clear: Kramnik is playing better than Fritz!

Game 1, = position used fritz to turn it into a win.
Game 2, I got away with it in game 1, lets do it again.
Game 3, same as 2.
Game 4, oohh they are on to me and my washroom scheme better tone it down.
Game 6, same thing.
That is what the numbers tell me.
I'm not taking anyside, just wanted to throw a fork into your statement. Other factors need to be considered 🙂

Here's the game. Go ahead and submit it to Danailov for analysis.
