Folded around to my SB(0.25/0.50)...I have 45h - raise to $2. BB calls. BB and I both have $50 in our stacks. I have seen BB play and is a solid player and is capable of making quite a few different moves.

Flop 5d7cQd - I bet $3 and he raises to $6, I call.
Turn 4s - I check (thinking check-raise) and he checks
River 8h - I bet $4 - he raises to $8
