It's much harder than it sounds. Firstly a top level player will match the top engine move 65+% of the time when playing legit, so it isn't that unusual to have a run of quite a few engine moves in a row (especially since they aren't independent, some positions are easier to play than others). Second, as Magnus has said in the past, if he has the ability to consult an engine at a single point in the game (of his choosing) he would be unstoppable. The reason is that in each game there are relatively few 'critical points' at which the result is decided.
