Play a solid closed opening as quickly as possible (the latter only if there is time control). Against the engine/cheater, the chance to play a draw from an open opening is 0%, in a closed one it is quite possible to even win (I played a closed opening and won).
Try to exchange pieces if this does not lead to a worsening of your position. The fewer pieces, the less chance of blundering.
Try to close the position tightly with pawns. It will be very difficult for the opponent to break through and you can reach move 151 and win (if you are playing against the engine) or win on time (if you are playing against a cheater).
If time is limited, cheater can always lose by time. Engine moves very fast, this won't work against him.
Chess engine Stockfish of any level gives up on move 151, even if he has a much better position. The usual engine that cheaters use does not give up, this won't work with them.
Remember the concept of "chess fortress". The engine almost always evaluates them incorrectly, in my game after move 37. Ra4 the engine writes -2.1, although it is objectively a draw.
The engine always tries to win. It can go for a slight worsening of the position if it can't win with the strongest moves. In my game it allowed me to take the a5 pawn for free, instead of fixing a draw (50 moves without taking or moving the pawn), I could also move Re8 on move 147 (in this situation there was no point in playing for a win, it was enough to hold out for 4 moves before the engine resigned). - - - Please like the blog if you enjoyed it. Once this blog gets 10 likes, I will use all of the above to try to win Stockfish level 8 as black with time control! - - - P.S.
