80/160 Hand... standard play against a good LAGGGGY player

[jayheaps]

7-handed as part of a mixed game.

Under the gun with KQ spades, folded to villian a very LAGGY player who plays very well post-flop. Having played against him much live however i know he is a winner in the Stars 100/200 game. We had played together a couple times, usually short-handed. I had been playing relatively tight lately (mostly in stud-- this was the 2nd hand in this round of holdem)

Villian isolates me on the button. I call.

Flop: Q J 7 (2 diamonds). I bet, he raises. I decide to just call. (and this is not because I think i dont have the best hand.

Turn: 9 diamonds. I bet. He raises. I call.

River: I check, He bets, I call.

Thoughts?
