I dont like this play but I respect it. Personally I will never put all my chips in with an unmade hand against an OP who has me covered. (unless im short stacked or pot committed.) But, at least you were the bettor, and not the caller. He would of put you all in or virtually all in on the turn prob anyway when the board dodged the 3rd spade. If you would of called for all or most of your chips to see if the river made your flush or Aces, then you made the right play. Did he take a while to call? I think I probably would of had a difficult time calling here if I were him.

BTW...nice carpet dude, it really ties the room together...
