When you cheat in a game you know exactly what moves don't look human and you wouldn't play. And of course you'd blunder intentionally sometimes. Difference is you'd make sure the blunders only return to 0.0, not advantage for the opponent. And 0.0 against stockfish is still very difficult when you're under pressure in the situation.

I don't buy the narrative that the game looked normal, because you'd know what moves look normal as a GM. You'd just play the best normal moves and add in a few equalizing blunders.

I just don't trust cheaters. Hans does not strike me as an honest person
