Villain is loose preflop caller, but gives up if flop doesn't help. It is first time in the session that he check/raised my cbet (I was cbetting ~ 100% of the time). Based on his previous play I believe I had close to 0% folding equity here, so my implied odds are 11.83-to-1 for (4 outs) 11.75-to-1 shot. Only problem is that I couldn't really get all those numbers at the table, I just figured out that he will not fold and that pot + effective stack were more than 10x amount to call. Sure enough, I've got my straight but still can't get rid of the feeling that this was bad play.
