BB checks, and MP checks really suspiciously, I dont know how to describe it really but it was a timing tell that set an alarm off in my head. Anyways I bet the pot at .85, BB calls, MP raises to 4$.

I have one spade in my hand FWIW.
Call and see a turn because most likely he has a set? Or repop it? Would you play it any differently with 100bb stacks?
