I think you're ahead on the flop, so I'd raise. You need to punish guys like this who play too many hands when you pick up a good hand and hit. The Q isn't enough of an excuse to slow down in my mind. The raise also gives you the free card option, if you want it, though you got that anyway, so go figure. I also like raising the river and calling a re-raise. Not ideal, but I think too often SB has a weak pair (or two-pair) that he's betting now after your show of weakness on the turn.

Strategy at this table is pretty basic: play decent hands and bet/raise for value. I think you're playing these guys a little too cautiously.
