What do we think of villain's complete here pf? Since OP indicates villain is unknown, I would think most players in SB raise if it is folded around and BB is unknown with just about every hand that beats hero. Certainly all pps, AK, A10, K10, QJ, and maybe even K5 and A5. It seems like unless villain is incredibly passive his most likely holding is exactly 10 5, in which case hero's river push is an excellent play.

That said in the heat of the moment I probably check behind the river too.
