FTP 6max $22 rebuy-BvB battle, turn flush-->fold river?

[swede554]

6-max $20 rebuy on Tilt. First hand back after the 1st break. Avg. stack around 8k. Blinds 50/100.

I got moved to the table approx. two rounds prior to the break, and thus far the SB had been quite. I doubled up a shorty right before the break w/ TT<AJ.

SB-15k
Hero-7.5k

Folded to SB who min-raises. Hero call in the BB with 4[img]/images/graemlins/heart.gif[/img]2[img]/images/graemlins/heart.gif[/img].

SB checks, Hero bets 200, SB calls.

SB shoves, Hero folds.
