2 pair up against possible flush
 

Only 25 or 30 hands on opponent, so stats were pretty useless.

Full Tilt No-Limit Hold'em, $0.10 BB (5 handed) Hand History Converter Tool from FlopTurnRiver.com (Format: 2+2 Forums)

Button ($2.55)
SB ($13.90)
Hero ($12.90)
UTG ($5)
MP ($9.95)

Preflop: Hero is BB with A[img]/images/graemlins/spade.gif[/img], 4[img]/images/graemlins/club.gif[/img].
UTG calls $0.10, MP calls $0.10, Button calls $0.10, SB completes, Hero checks.

Flop: ($0.50) A[img]/images/graemlins/heart.gif[/img], 3[img]/images/graemlins/heart.gif[/img], 4[img]/images/graemlins/heart.gif[/img] <font color="#0000FF">(5 players)</font>
<font color="#CC3333">SB bets $0.5</font>, <font color="#CC3333">Hero raises to $3</font>, UTG folds, MP folds, Button folds, SB calls $2.50.

Turn: ($6.50) 9[img]/images/graemlins/diamond.gif[/img] <font color="#0000FF">(2 players)</font>
<font color="#CC3333">SB bets $6.5</font>, Hero ???

I know I'm not supposed to go broke in unraised pots... but can I fold this against an assumed donk at 10NL?

Thoughts on all streets appreciated.

I probably fold this. Some of the time you are good, but he will often have a heart in his hand when you are and not be far behind. I should do an equity calculation here, but I am too lazy right now. [img]/images/graemlins/blush.gif[/img]

Looks like a weak flush to me (maybe a str8) or maybe pair+nfd. Our equity is not so good, because they usually don't play draws this agressive and they would slow down with Ax. On this flop you're either not far ahead or far behind. I'd fold turn.

Re: 2 pair up against possible flush
 

About the best-case realistic scenario for you is that he's got a good Ax, but he might raise a lot of his good Ax hands preflop. I guess he could have A3 also, but you're still behind most of his range here.
