The BB pushes back

[mihain]

I would check the turn.
if he is beaten is not likely he will improve on the river(u favourite with many holdings) so even if u call the river is same cost of 1 bet u made on turn exposing yourself. With same cost u can get someone who would fold to bluff(this is the guy who would fold to your bet and this is the only way to make him pay) or someone with a monster hand or very weak check the river to you at no extra cost.
