What do you put him on?

[JTG51]

.50/1 blinds. I'm new to the table, the BB is unknown to me.

I limp UTG with A[img]/images/graemlins/diamond.gif[/img] Q[img]/images/graemlins/spade.gif[/img] Q[img]/images/graemlins/club.gif[/img] 3[img]/images/graemlins/diamond.gif[/img]. Three other players limp and the SB completes. The BB raises to $2 and everyone calls.

Flop: 9[img]/images/graemlins/club.gif[/img] 6[img]/images/graemlins/diamond.gif[/img] 2[img]/images/graemlins/diamond.gif[/img]

BB checks and I bet the pot, $11.40. Everyone folds to the BB who min-raises to $22.80. I call.

Turn: 8[img]/images/graemlins/spade.gif[/img]

He bets the pot, $54.75.

I thought his preflop and flop play were a little unusual and wasn't sure what to put him on. What range of hands would you put a typical player on after the flop check raise, and how, if at all, does the turn bet change your read?

Also, feel free to comment on my flop play.
