how do cheaters cheat,I am curious
They use a bot that tells them what the best move is in any given position. (The "Learn --> Setup Position" section of this website is also used.)
Generally speaking: If your opponent takes like 5 minutes to make a move, then starts playing flawlessly, they're cheating. 100%.
There is also multiple ways they can try to hide it, such as spending inconsistent time on each move, intentionally blundering pieces, resigning won games to reduce their win rate, and only using the engine enough to just barely beat the other person
If you are asking so you can cheat tho I wouldn’t recommend it xD
The perception of cheating levels is orders of magnitude more than the actual amount.
