I mean, I am pretty aggro player so I expect to be moved on sometimes.

Thats why I have to just call flop, pushing obv shuts down a bluffer. But on the turn what do I make of this? I feel like this fold be a real tight fold. He has to assume an over pair for me I would think. So my thoughts were that any 6 was potting (which I beat most of), and of course the smaller percentage of bluffs probably pushes too.

Results below, please post first.
