I like it. He has to have a really good King to call and that's a good turn. This is a case where he has a full house or Ace high. Any playback and you can get away. If he just calls, you're done with the hand, too. The raise is good enough to knock out the straight draw which contains overs along with a spade draw that could've developed.

I prefer a quick CR on the flop for around the pot, though. If his bet's too expensive that a CR would be too costly, you can get away.
