Pre Flop: (pot: 1.5 BB) Hero has Kh Ac
Hero raises to 2.16 BB, MP raises to 7.7 BB, fold, fold, fold, fold, Hero calls 5.54 BB

Flop : (16.9 BB, 2 players) 6d 7c Qs
Hero checks, MP checks

Turn : (16.9 BB, 2 players) As
Hero checks, MP bets 11 BB, Hero calls 11 BB

River : (38.9 BB, 2 players) 5s
Hero bets 14.5 BB, MP calls 14.5 BB

Would you bet river here?

My reasoning is that I will call a bet up to 2/3 pot or so so with betting out I set a price that is less in return I give up some bluff catching potential.
