1) do you have any reads? what are the stack sizes? This would be helpful.
2) check raise is a terrible idea on this two to a flush board. lead for $4. furthermore, your check raise was weak. it should have been to $3.5 at the very least.
3) beat him into the pot putting all of your chips there. if he has a set, he played it poorly IMO in a three-handed game by not raising. reload and add him to your buddy list. if he's chasing a flush, you're a nice favorite (this is my guess)

Do you have the A [img]/images/graemlins/spade.gif[/img]? This would make me push even faster.

P.S. You're not in LP. You're the big blind. this is a big difference. you might act last preflop, but you're first to act in every other betting round.
