Fold, call, or raise?
We are playing 2/5 with a $350 effective stack. I have JcTc from the BB and the Villain in the HJ opens to $25, I call from the BB and a player from MP calls. We are going 3-way to the flop with a pot of $75. The flop comes AcKc5h and I check, the MP checks, and the villain bets $55. I figure I could raise to about a pot size bet getting pairs smaller than K to fold and maybe even some weaker kings (although this flop is generally good for his range). Since all in was only a bit more I shoved for $268 dollars (putting him all in). This player is relatively unknown but in a previous hand he had bet all three streets with a bluff so he likely will play out of line on occasion. Is this a fold, a call, or a raise and if so how much?
