98s small blind
 

10 handed 5/10 game table is generally weaktight with a couple donators

UTG+2 villain (48/0/1 small sample) limps, folds to me in SB with 98s I complete, BB checks

Flop(3sb)
9T3r

I bet, BB folds, villain raises, I call

turn (3.5bb)
7 (now there's a flush not my suit)

I check/call

river (5.5bb)
5 non-flush

do I need to show down here?


edit: clarification

Re: 98s small blind
 

I would fold on the flop against most opponents. He's probably got either a Ten, or a straight draw, which may include 2 overs, meaning you're about even money. The pot is small enough that you won't be leaving too much on the table if you do fold a better hand, or would have improved. As it stands, I think you made the right play on the turn and river. All you can beat on the river is a QJ that continued his semi-bluff the whole way.

I don't like folding the flop at all.

I'll assume hero is behind on the hand. He has 5 outs for two pair or trips and an additional 1.5 outs for the 0 gap backdoor straight draw for a total of 6.5 outs. For a 6.5 out draw you need to be getting approximately 6:1 to call which happens to be what the pot is laying.

In addition, you don't to bet on the flop and then fold to a raise unless it's clearly right to do so as you don't want to encourage your opponents to throw random raises at you with overcards, gutshots, etc.
