Just an FYI. The site doesn't like or allow discussions of cheating in the forums.
Selective Cheating/Engine Use
The perception of cheating levels is orders of magnitude more than the actual amount. The vast majority of games and players are clean.

A question - and I apologize in advance if this has already been discussed here.
Is the chess.com algorithm able to detect when players only cheat during critical game situations? For example, consulting the engine for a sequence of 2-3 key moves, and then playing out the rest of their game at a natural level of play?
