This is a different situation...but while im on here, might as well post a hand. This is the same hand except in position.
His turn bet appears reaaly weak, and i feel like pushing but i know he'll be commited. The only hand im ahead of is a KhQh imo. Villian is 20/16/3. Is his 'less then half the pot sised' turn bet a small blocking bet, or a small bluff inducing bet with a hand like jj.
Villian is 20/16/3 only 50 or so hands...
