ub 200k: I float

[grafyx]

UB 200k.

blinds 50/100

I have 4470 in the CO.
BB has 7170.

I have T [img]/images/graemlins/club.gif[/img] J [img]/images/graemlins/diamond.gif[/img] and open to 300.

BB calls.

flop is

8 [img]/images/graemlins/heart.gif[/img] 2 [img]/images/graemlins/heart.gif[/img] 3 [img]/images/graemlins/diamond.gif[/img]

BB checks. Usually I cbet this flop, but decided to check this time.

turn 7 [img]/images/graemlins/club.gif[/img]

bb bets 350 and I call.

My plan is to bet 900 into 1350 pot on the river if he checks and it's any of the following cards. AKQJT9 or a heart.

Thoughts?
