200nl - A7s in weird MW 3b pot.

CO is a weird brokenstack type who has reg stats over a few hundred hands.
BB is a 30/21/9 3b/8% 4b (low so far) over 2k hands, but I haven't played him in a while and don't recall anything eventful.

I don't think the flop should be played any differently, but I'm not sure exactly what to do on the turn.
