How Much Do the Pros Actually Play a "Game Theory Optimal" Style?

"Game Theory Optimal" — or "GTO" — is a term often heard in poker these days. Often the term is used imprecisely as a general reference to the "best" style or strategy in a given situation, though in truth it has a much more specific meaning than that.

To employ a "GTO" style means to play in a way that is impossible to be exploited by an opponent. It means always making "optimal" decisions that ensure you maximize your expected value in any situation. To play such a style perfectly would also mean that the very best your opponent could do against you would be to break even.

Such a style can be readily employed in simple games, but in more complicated ones like no-limit hold'em it is hard actually to play a strict "GTO" style. Besides, in poker players almost always demonstrate certain tendencies that suggest sticking with a "GTO" strategy isn't necessarily the best option — rather, an "exploitative" style that responds to opponents' weaknesses can sometimes be a better choice.

Our Laura Cornelius caught up with a number of poker pros to ask them how frequently they themselves could be said to play a "GTO" style. Their responses suggest the current "GTO" debate in poker is in a way an updated version of the old "math vs. feel" one.
