Given that villain is a TAG and that he raised the K high flop, I would find this to be an easy check/fold turn UI.

The only thing you're beating is a spade draw, and your opponent isn't likely to have that often enough to justify calling down.

If that is a little weak tight for your tastes (and I suspect it may be), then I don't see any problem with a bet/fold line on the turn, provided a blank hits.
