I tend not to be so terribly interested in rebluffs on the first hand of any encounter.

In this circumstance it would be more of a "free showdown" raise since my hand can't stand any more action, but I don't really like this spot for it because of how in the middle of my range that K is.

Thrakkar's bet doesnt look like its going to fold to a raise, and is more likely looking to threebet since I'm going to be tempted to raise with some of my jack hands and lots of my king hands.

If the turn card were a low blank I'd be more inclined to rebluff. Thrakkar leading on the K turn shows considerable strenght though, and is enough to cause me to fold outright.

Also, if I think he's bluffing I'd do better to just call down.
