Algorithm to determine what a "human" move is

[Peperoni]

Hello,

Is there a more or less accurate algorithm that could determine if a move is more a "human" move or an "engine" move?

Thanks,

[Nay Lin Tun]

This is lichess cheat detection system. ( please note,, you need millions of human games data for, time usage,accuracy, rapid rise in elo etc). Without a chess server, the code is incomplete and not powerful.

Hello Nay Lin Tun,

Thanks for your answer. I was more thinking about detecting if in a game between Engines, which moves could strong players find and which ones they could never find.
The idea was not to apply that to a specific chess player

[Nay Lin Tun]

Accuracy is pretty much useless in a single game. ( A 2000+ player's accuracy in closed position in stonewall will be 95%+ accuracy, but the same player in open tactical position accuracy will be 50-70%).

Time usage is the critical data. In fact, for cheat detection, you need combination of a lot of factors in a series of games.

[Dann Corbit]

A famous AI test was to put a computer and a GM on the other side of the game (hidden of course) against an opponent.
AI was supposed to be achieved when you could not tell the difference.
Kind of flawed, of course, but interesting to think about

Hello Nay Lin Tun,

Granting that a strong player can match Sf12 on a 1 sec/move on certain hardware or around depth 16 to 20 per move or so, we can analyze the game played by engines at that move limit.

As an example I have analyzed couple of games from the tcec 19 sf with Sf12. Yellow is for the move from the game. Green is Sf12's best at 1 sec/move. If color is yellow-green that means the move in the game and Sf12 best move are the same.
