$11's pocket 9's post flop w/ OESD

[Dr_Jeckyl_00]

I have no idea how to play this hand post flop... I thought about betting 1st, but I checked and when it got back to me I figured I almost had odds to call (and definitely did when olycash called)... but it would be expensive. Any thoughts?

Fold 'em.

I didn't read the results, but you're not closing the action, and you're vulnerable to a c/r from the p/f raiser. I would fold 'em.

Edit: You don't know that olycash will call because you act before he does. You don't know where you are in the hand by just calling either, but your hand isn't necessarily strong enough to raise. 2 other reasons I like a fold.
