So basically chess with landmines. Every move will be contested (because why wouldn't you? there are no downsides and only upsides)
So every move you make (I'll be watching you) could end up being the top move. Even if you run the chess engine yourself to decide what not to play, you're still at risk of bad luck because you happen to run the chess engine on a faster or slower machine than the person checking for the top move, and they diverge.
EDIT: Never mind, contesting and getting it wrong causes you to lose - that's the downside.
