I open AcAd to $20 utg, I get four callers both blinds fold. Flop comes Ks6s4d, I bet $65 all players fold except the button who calls. I had approx. $450 to start the hand, button covers me. The button is a middle aged recreational regular who can be a little fishy at times but isn't really super fishy overall. He would definitely just call with AK in this spot pre flop, so don't rule that hand out of his pre flop range here because he didn't three bet me pre flop. Turn is 8c, I bet $115, he thinks for a few seconds and moves all in. At this point I'm getting close to 3 to 1 on a call? I'm curious as to everyone's thoughts on this spot, my line, and what you do now facing the turn shove as I played it?
