I just called... and villian showed 55.

I honestly think pushing the turn after the turn raise is best, but lately I've been getting screwed by nut flushes. This is a fairly typical example of it too: a lot of players will keep chasing until the third flush card hits and then they start pumping the pot up in my face. I admit that since I have a strong flush here myself I'm being scared of ghosts, and just calling the turn lets him fill up without committing his entire stack. I usually am more aggressive in this situation though, so no worries.
