How do I play this 52o?

[tessarji]

Why do these hands always happen to me? This isn't a bad beat post, I want to know if good players lay this down.

Hero has 5[img]/images/graemlins/heart.gif[/img] 2[img]/images/graemlins/spade.gif[/img] in BB

Reads: SB just sat down 1 hand ago. MP1 is a fish, other players seem solid/good.


MP1 limps, MP2 limps, CO limps, SB completes, I check.

Flop: A[img]/images/graemlins/spade.gif[/img] 3[img]/images/graemlins/diamond.gif[/img] 4[img]/images/graemlins/club.gif[/img]

SB bets, I raise, MP1 calls, MP2 3 bets, CO folds, SB 4bets (cap), I call, all call.

Turn: 3[img]/images/graemlins/club.gif[/img]

SB checks, Hero bets, MP1 calls, MP2 raises, SB folds.
Pot: 16 BB

I feel I'm obviously beat. But, I have been wrong before. Throw it away or pay off a likely 2BB?
