<font color="#CC3333">UTG raises to $1</font>, <font color="#666666">6 folds</font>, SB (poster) calls $0.75, Hero calls $0.50.

Flop: ($3.50) 8/images/graemlins/spade.gif, J/images/graemlins/diamond.gif, 4/images/graemlins/diamond.gif <font color="#0000FF">(3 players)</font>
SB checks, Hero checks, <font color="#CC3333">UTG bets $2</font>, SB calls $2, Hero calls $2.

Turn: ($9.50) 8/images/graemlins/diamond.gif <font color="#0000FF">(3 players)</font>
SB checks, Hero checks, <font color="#CC3333">UTG bets $10</font>, SB calls $10, Hero?

The SB's check call on the flop and turn is what sets off the alarm here... Thoughts?

lead the flop or check-raise BIG.

you may as well have six high on the turn.

Assuming you don't have a read on either player, I don't see any option but a fold on the turn.

With flush draw+gutshot straight draw, I like to lead this flop for a PSB.

As it stands... UTG isnt really slowing down with the flush on board, and neither is SB... probably gotta fold it.
