Raise flop - I find these small little donk bets are often weak made hands/weak draws. I find I get a lot of folds if I raise them, or they just call terrible odds with crappy draws. (although sometimes I spazz out too much against them)
as played shipping turn is fine with TP, gutshot and NFD and you have so little behind
Oh, and make sure to always refill to 100bb!
(unless you play shortstacked)
