In your opinion, how close can the best pros play to optimally (in a game theory sense)? Put another way, when they play each other, what percentage of their game is based on "Don't be a sucker" as opposed to exploiting perceived leaks in each other's games? Does this vary between different games? E.g. is limit HE played closer to optimally than say Omaha PLO at the highest level?

These are vague questions, since nobody knows what an unexploitable strategy is for any form of poker. But I'd love to hear your informed speculation anyway.
