LAG Hand?

[hit_the_set]

I have been trying to incorporate some LAGginess into my game and this is an attempt at it(figured I had the stack size to play loose. I was playing party yesterday and ran into one of my favorite fish. The guy is very predictable postflop and has seen me bluff quite a bit. I was willing to give it up on the turn. I did get lucky on this hand, but anybody think I should check the turn here?
