6 handed 600NL game.
Me $750 - in CO
BB $550

I have a pretty loose image, I pretty much continuation bet all the time. BB seems to be fishy, playing too many hands and limping and calling too much preflop, doing the nomal fishy stuff.

My hand:

UTG limps so I raise it up to $27, my standard pot raise preflop, BB calls, UTG folds.

Flop: ($60 pot)


BB checks, I make a bet of $45 into a $60 pot like I usually do, BB minraises me to $90. Whats my play? What would you put him on?
