[sy_or_bust]

During the hand, I worried about paying 2BB on the turn when the K is a very likely defending hand for my opponent and I have many outs. Inducing a bluff on the river when I miss is nice too.

Now, I think you both are right. My hand is really vulnerable, and BB isn't raising the turn very often. A bet doesn't allow a free card for overcards and straight/flush draws either. I'd rather make this check with a pair that doesn't rate to be outdrawn so often.
