2/5 game with effective stacks of 780 (me). V in this hand is a competent player that I have played 25-30 hours with over the past few months. He has only been playing a couple years, rarely seems to get way out of line and has approached me several times to get my opinion on hands that he has played etc... I know he studies the game and is trying to move up. I think he occasionally calls pf raises a bit light, but I still think he is a winning player. Onto the hand....
Folded to me in mp and I raise to $20 with KJcc. 3 callers including V on the button.
Flop (73 post rake and BBJ) 456 all clubs. The bb checks and I bet $60. Thoughts on bet sizing here? Everyone calls.
Turn (313) 2h The bb checks and I bet 240. lp player folds and V shoves and has me covered. bb folds and accidentally exposes 77 with the 7c. I have 460 left in my stack and the pot is 1013. I do not think V is bluffing. I do think that it is possible that he has a hand like 89cc and is shoving because he thinks I could have AA with the Ac. He could also have hands like AQcc, QTcc or smaller suited connectors. I'm not sure if he makes this play with a set. I've rarely seen him get way out of line.
So...what do you do?
