sb is 17-11-1 with low fold to cbet (flop 46%/turn 25%) and very low raise frequency postflop. If he bets/raises he has it. He has 6x/pair+gutter/99-QQ here a lot. He doesn't have a set on the flop.
bb is 15-10-4 seems decent over small sample. Meh, i don't think he calls a set on the flop either, but he'll be calling anything he thinks might turn some value.

Turn $11?
