I have AhKc7h5h in late position. I called a $15 straddle. 5 people in the hand. I have $500 behind me. Flop is Jh2c8s. It gets checked through. Turn is a 6h which gives me an open ender and nut flush draw. Checked to me again and I bet 2/3 pot ($60). Guy behind me snap calls and everyone else folds. River is Jc. I bet $100 as a bluff. I figure hes on a draw and its going to be hard for him to call here. He tanks forever and calls and shows me a pr of kings with the king high flush draw. Question is: Is this a good bluff? Should I have bluffed more? I'm thinking maybe I shouldve bluffed more and it wouldve worked.
