Final Pot: 6.83 BB

On the flop it looked like a nice hand to call down with, hoping to see AK.

After the turn brought a K, I couldn't think of a hand that would cap preflop that I would be ahead of here.
JJ, QQ, KK, AA, AK, AQ, KQ

Do you call down here and hope he has 99? If the only big cards showing were QQ I would have called down.

At the time I was running really bad, is this a weak-tight play motivated by a recent string of losses?
