Villain was 29/11/39 over about 30-40 hands.
I have to win the river 1/3 hands to make this call here.

The tanking was trying to put him on a range. what do we think against a typical 29/11/39?

I am still in session, I just wanted to see what you guys thought. All of his prior bets that i can recall were pot bets or similar button press raises.
