So I hadn't caught any cards for the whole sessions so far, so decided to limp in this one.

Ultimate Bet No-Limit Hold'em, $.25 BB (8 handed) Hand History Converter Tool from FlopTurnRiver.com (Format: FlopTurnRiver)

SB ($37.70)

Preflop: Hero is UTG+1 with 8, T. SB posts a blind of $0.25.
2 folds, Hero calls $0.25, 4 folds, SB (poster) checks.

Flop: ($0.50) 5, 3, Q (2 players)
SB checks, Hero bets $0.5, SB calls $0.50.

Turn: ($1.50) 6 (2 players)
SB checks, Hero bets $1, SB calls $1.

River: ($3.50) 5 (2 players)
SB checks, Hero checks.

Final Pot: $3.50

I am never sure what to do here. I feel if I fire out another bet I'm probably spewing money since he called the two previous and I got jack. If I check I feel super weak, have no chance of taking the pot and my weak cards are exposed.

Better for table image to just fire out another and take a chance, then even if I lose it maybe I get some action next time on the river when I do have something since I appear to keep betting crap?
