Will my account get flagged / be accused of cheating? • page 1/1 • Game Analysis • lichess.org

I think I just played my best game of all time. When I analyzed the game I has 0 inaccuracies, 0 mistakes and 0 blunders. I have 15 ACPL and a 98% accuracy in a long 61 move game. Since I just made this account, will the algorithm or the moderators think I cheated??

Well if you played engine-like moves, the moderators will get suspicious of you.
Also, a very high accuracy percentage isn't necessarily indicative of superhuman, "GM-level" play. If your opponent blunders early on or plays consistently subpar moves, you will have greater chances to capitalize on your mistakes. This can lead to a very high accuracy. If this were to be your case, then moderators won't be suspicious of you.

Your time usage on every move is inconsistent, which is a good sign.

Overall, I'd say the moderators will unlikely close your account.

A single game might be suspicious as a curiosity, but is very little evidence weight.

In your case, this single game is not even slightly suspicious...

The reality of the game is this... The first 20 moves are so are pretty normal moves form both sides. Nothing really sharp or creative, just fairly standard chess that is well within the capabilities of someone with your ratings. On moves 23 to 25, your opponent uncorks 3 bad moves in a row, which you correctly punish. In these move, the position changed form basically a draw, to a completely lost one where your opponent could even consider resigning.The game continued another 35 moves during which you played competent chess, to not give anything back and convert the win, but it is important to understand how accuracy works.

During these last 35 moves, you did not play the absolute best move every time, or 98% of the time, or even 50% of the time. You choose the best move well under half the time, and indeed, several times, you played the 4th best move or worst... Why then the high accuracy? Because your moves, while not the best, were still easily good enough.

Accuracy measures how much damage you do to your winning chances... If before the move, the computer thinks the position has a 99.9999% chance of being won with the best move, but you play the fifth best move, and now only have a 99.999% chance, this is a very small amount of damage. The fifth best moved preserved almost all the advantage, so contains only a tiny sliver of inaccuracy.

The points is that, while this is a very solid game, and given your rating, you have every reason to be very happy with it. Form a "potential cheating" point of view, the high accuracy score was almost entirely driven by a 3-move window in the middle... As above, even a full game of strong moves would not be enough to be considered evidence of anything, but 3 moves is even much less than that...

So, even if someone (a moderator) for some reason decided to look at this game, but answer is no, they would not for a second think you cheated.

In one game... Certainly not... The only time they would consider taking action on a single game is if the actively detected an Engine being turned on (in which case the system reacts automatically and immediately).
