Final Pot: $67.55

EP villian is unknown(later found to be TP), has been sitting for less than a rotation. LP villian is a somewhat solid regular, possibly tilting though from a bad beat which is why he's short stacked.

I only question my call because EP villian did, to me it's a no-brainer but maybe I'm wrong. Also any reason to push preflop? I figured with the pf action the rest was going in regardless. Thoughts?
