99 w/tilter building pot

[danzasmack]

I open 99 UTG+1
Guy right behind me has 6 SB's left and is ready to just shove them in i'm sure of it. Anything that might see a flop he will raise me with. So of course he 3-bet.
SB who is a bad player (not like bad lag, think like 45/10 kinda guy) cold calls 3.
I cap and both call.

Flop is J[img]/images/graemlins/heart.gif[/img]7[img]/images/graemlins/club.gif[/img]3[img]/images/graemlins/heart.gif[/img]
Bad SB leads out, I raise, tiler calls all in, call.

Turn is T[img]/images/graemlins/spade.gif[/img]
Check, I check.

River 4[img]/images/graemlins/diamond.gif[/img]
Bet, I call.

I think I played this bad but maybe not. What if the river is a heart are you then folding?
