NL200 - 2.5 stacks deep w/mid set. Bet size?

[Sirasoni]

I would've bet something like 150, with plans to get it in on a blank river obviously.

I would also put it in on a spade river if he checked to me, since I think he might front bet ai with a made flush, though of course I could be wrong :P. If he does go ai on the spade flush complete, it'd be hard, and I'd probably call it simply because of stack sizes at that point. Though I think I usually lose in this spot so..
