How would you all have played this?

[Sebastian Knight]

I would have made it 3 bets on the flop, but that's just me. Your play could be best. In addition to the hands that are beating you, villain could have something like AQ or JJ or KQ or an A or K of spades. Or worse. I'm not giving him a cheap card.

Turn call is fine -- compulsory, in fact, with 9 outs to a boat, not to mention the one beautiful K left in the deck.

You're probably beat on the river and you should probably fold. I'm usually not good enough to do it, though, getting around 7:1.
