big blind with a decent stack

[gumpzilla]

$50,000 R&A at Paradise. Blinds are 300/600.
I pick up 62o in the BB. CO, button limp in, SB completes, I check. I have about 20,000 in chips, button is big stack with 40,000, SB and CO both have about 8000 after calling. We're still pretty far from the money.

Flop (pot = 2800) T [img]/images/graemlins/club.gif[/img] T [img]/images/graemlins/heart.gif[/img] 6 [img]/images/graemlins/club.gif[/img]
SB checks, I bet 1500, CO calls, button folds, SB calls.

Turn: (pot = 7300) T [img]/images/graemlins/spade.gif[/img]
SB checks, I bet 3000, CO calls, SB folds.

River: (pot = 13300) 9 [img]/images/graemlins/spade.gif[/img]
I check, CO pushes for about 3500 chips, I call.

Thoughts?
