Chess sites catch cheaters by looking for statistical fingerprints in hundreds of moves—unnatural consistency with an engine's top choice is a big red flag. One move is never proof because even I, after correcting papers all night, might accidentally play a 'brilliant' move! It's about patterns over the long haul, like how I track my students' progress week to week, not one good test. Honestly, analysing these games sometimes reminds me of grading homework, looking for that sudden, suspicious leap in understanding.
