Cheating might break tournament or social rules, but it doesn't break the game. So yes.

And any online game can be "cheated" by having someone better play in your place, or abusing the ranking system, but again that is breaking a social/meta-game rule, not a game rule.

Cheats in FPS games effectively break the rules of the game (wallhacks), or do things that are entirely impossible for a human (instant-lock aimbot). Chess and Go don't have that problem.

I suppose the difference is moot when everyone imagines that they're in a tournament playing for clout, and not playing to learn strategy.
