Hero (BTN): $5.07
SB: $3.69 (32/16 over 19 hands)
BB: $5.00 (21/17 over 79 hands)
UTG: $5.12
MP: $4.91
CO: $8.35

Pre Flop: ($0.07) Hero is BTN with A 7
3 folds, Hero raises to $0.15, SB calls $0.13, BB calls $0.10

Flop: ($0.45) 6 T 9 (3 players)
SB checks, BB checks, Hero checks

Turn: ($0.45) 8 (3 players)
SB bets $0.20, BB raises to $0.60, Hero calls $0.60, SB raises to $1.40, BB calls $0.80, Hero raises to $4.92

So this hand pretty much speaks for itself. If I can ever fold a straight at NL5, I think it would be this hand. Should I fold here after the SB raises to $1.40? I assume calling the 60c (Or even raising it) is a good idea.
