He caught good and I caught mediocre. Do I fold here, or do we see 5th?

I have made a low. He has a better looking board, but may have paired. He only called the bring-in, not raised it, so I do not believe he has cards like ace 2, ace 5, etc. I do not have much money left at this point. Call, raise, or fold?

*** 6TH STREET ***
Dealt to VILLAIN #2 [3c 6s 4s] [5s] Bets
Dealt to Hero [4d 8c 3h 9s 5d] [7d] Calls (all-in)

I caught good, he caught better. I am only beating a bluff, and even if I am winning, he has outs to beat me. Call the last little bit?

Based on his 4th street bet, his bet on the turn is going to be a value bet most of the time because he has already made a his 7 low (or 8 if he has an 8 down). As you're really only drawing to an 8 low, this is probably a fold on 5th.

the call on 4th is fine. the call on 5th is margainal at best. i'd probably fold, if he bluffed, oh well. you made the right play. the call on 6th is a definitely toss. there is no way you're beating him here.
