Stopping Bluffs

[David Sklansky]

This is a simple question if you can do the math. So I ask the math guys to not answer it. Plus I will be a bit vague numerically to keep things to estimates.

But this is an important question and I want to see how close you instictive types will get to the right answer by the seat of your pants.

You have an opponent who you play with regularly who bluffs alot on the river when the pot is pretty big and he is headsup with you. You estimate that one out of three of his river bets are bluffs. So you are always forced to call and lose that last bet two out of three times.

You think you have the ability to intimidate him into bluffing less often. It doesn't matter how. That's a good idea(because you can now make smart laydowns) as long as you can keep him bluffing on less than what percent of all these headup hands with you?
