Havn't read the thread past the original post so forgive me if what I say has already been covered.

I don't like PF. Raising to $4 just sucks IMO. I like $7.50 or just a limp, with emphasis on just limping here. The weaker and tighter the limpers are, the more likely I'd raise. Multiple limpers seem to have a way of protecting each other though.

Flop you are only raising like half pot, I'd probably jack it up a bit more.. but this situation since your raise did nothing but build a pot with a hand that over 7 out of 8 times has very little post-flop playability in a multiway pot.

Do you want to get stacked with 88 here? If the answer is no, I think you should just get out... I'd be very surprised if you were good here.
