Live hand, tricky river.

[gordongecko]

My line was flush at first, but he was just to confident with his bet even though the board paired. If this were any other guy I would consider just a call, or if the stacks were a littler deeper. I put any spades, and KQ in his range, given pre flop action. I figured the flush hitting was worth the risk of getting run over by a bigger boat, but I had a terrible feeling shoving. He insta calls and tables KQ for the bigger boat. I really put him on KQ, but I dont think I can get away from my hand here with the spade hitting. Would just a call be out of line here given my line on villain? Or does all the spade hands he could play the same way give me enough value to shove?
