Can't really draw any conclusions yet from the data. But I do find it interesting how many players have over a 50% hit rate. These are not top level players. So it must not be uncommon to be able to move match 1 out of 2 moves. Even after running the games with don's move filter.Don wrote:I have most of the first tournament completed using the new criteria:
1. Start at move 15
2. ignore easy moves unless they do NOT match.
3. ignore Houdini moves below 7th iteration (don't match those.)
So basically if Houdini changes his mind any moves considered on 7th ply and beyond can be a match.
For a move to be considered easy or trivial Stockfish must like it on depth 1-12 and never switch away. If Houdini and the player like a different move it is not considered easy.

Re: Borislav Ivanov: a Lilov's add-on
I'm pretty sure that the strength of the player is not as highly correlated as one would think. I found this to be the case with the similarity tester for chess too. You can test any program against itself with a 20 to 1 time handicap and still easily see the programs are strongly related even though the 20 to 1 makes it hundreds of ELO weaker. This actually proved to me that move style is very much like a fingerprint.mwyoung wrote:

I am running the tournament again using Komodo now - and I'm already seeing that the move matching percentage for any given player is completely different than it was with Houdini but I need more samples to say for sure how this will end up.
Do you want to see something funny? I'm also running the tournament where Borislav had a poor performance rating. I have only processed one of his 4 games so far but look (he is position 29):

I'm also processing some games for Carlsen - extracted from twic data - games of the last year or two.
After 4 games are processed Carlsen is matching 47.37 percent of the games. I think I have over 100 games.

Re: Borislav Ivanov: a Lilov's add-on
This is not going to be a simple process it looks like. If there is no good corralation been rating and move matching. I would like to see if a more tactical player like nakamora or a morphy would have a higher hit rate. This is going to take some time to work out the patterns. Many player will need to be looked at with the deveation between winning tournaments. And doing badly in tournaments. To see how the hit pattern changes or stays relatively the same.

Re: Borislav Ivanov: a Lilov's add-on
I'm started a run against several thousand twic games - but I'm restricting it to GM vs GM. I hope to get many hundred games in with lots of samples per player.

I have 364 games evaluated now with 129 players total and growing.
At the moment the highest match rate for a single game where there are 20 or more samples is 75% If there are 25 samples it's 69%. My feeling now is that (using my methodology) seeing a match rate of 75% or higher for a single game (with at least 20 samples) is perhaps not a common occurrence but not uncommon enough to be suspicious.
It's probably more about how many moves you can sample that it is games. We can figure this out later.
I'm hoping that we can show that no player is predisposed to wandering very far from the median which is about 45. Carlsen's median was about 47 - a little above the median. I think the type of game will probably affect the statistics a lot and perhaps even the openings played. My easy move filter seems to help a lot though.

Re: Borislav Ivanov: a Lilov's add-on
Yes it will be interesting to see the results of the GM vs GM games. I think it is important to use them as the baseline. After all we are trying to separate human play for computer play.Don wrote:I'm started a run against several thousand twic games - but I'm restricting it to GM vs GM.

It will be interesting to see if you are correct about the median score of 45, and what type of deviation we see across a wide range of GM players.
If you would include the Capablanca games in the GM base. I have always heard GM Capablanca has the highest move correlation with computers. It will be interesting to see if this is true, and if true what deviation from the median do we see in the data.

Re: Borislav Ivanov: a Lilov's add-on
I have two games were a player was thought to be cheating in a chess tournament and even searched, but no device was found and the players was allowed to play. If you could run the two games to see what your program shows tells us. The player was thought to be cheating because of his rating 2165.
It was reported - that GM Larry Christiansen, who did not play at the world Open, ran the moves through the program Shredder and found that the last 25 moves matched those played by the program.

After 4 games are processed Carlsen is matching 47.37 percent of the games. I think I have over 100 games.
Don
I have 364 games evaluated now with 129 players total and growing.
At the moment the highest match rate for a single game where there are 20 or more samples is 75% If there are 25 samples it's 69%. My feeling now is that (using my methodology) seeing a match rate of 75% or higher for a single game (with at least 20 samples) is perhaps not a common occurrence but not uncommon enough to be suspicious.
It's probably more about how many moves you can sample that it is games. We can figure this out later.
I'm hoping that we can show that no player is predisposed to wandering very far from the median which is about 45. Carlsen's median was about 47 - a little above the median. I think the type of game will probably affect the statistics a lot and perhaps even the openings played. My easy move filter seems to help a lot though.
Even 100% match against houdini only for one of the players in many moves is possible
without getting external help in the game if both players follow some draw between houdini and a different program that they simply memorized at home and they can read
the relevant game that they memorized for example in this forum.
something like that clearly can happen if both players want a fast draw and there is a rule that forbid offering draws in the first moves.
