Single Table....Results to follow after advice.

4 people left...standard 3 payouts

Blinds 100/200

Hero 3rd in chips with 1,200BB
Small Stack 470
Villian 8,500 on the Button

Villian has been raising it up quite often with marginal hands, I've called and gone all in once before to become 3rd in chips and not last.

Villian raises 400 on the Button 700 total in the Pot
