Checking is awful FPS.

You need to bet here 100% of the time. If he makes it 3, then you can call and trap him for the river.

With the check you might occassionally get a bet out of a PP that you normally wouldnt but with betting you will get action from someone going for their flush or unlikely straight draw and then again if they hit on the river. Plus anyone with a PP is likely calling this down all the way regardless of your betting.
