I'd x flop. AP I'd fold to x/r, it's going to be hard for us to continue on most turns and we are low down in our range so we can afford to fold.

Blocker wise if we don't think he's cr Kx our hand actually becomes a great bluff catcher. We block sets straights 2 pair, and don't block flush draws. Just saying.

Think betting flop is fine, but fold to x/r. It's going to be hard to get our equity to showdown, and he played preflop passive, and has now taken an aggressive flop line. As played I think fold turn, we do block some value and unblock bluffs, but we don't really have any info on villain and he has taken lines that suggest he is a weak player, in spots like that I prefer to take a straightforward approach and just play the value of my hand.
