You're in for that 200 anyway. Like, if V had instead jammed the 200 on turn, you're getting like 4 to 1 and the same equation applies, you kind of have to call. So the reason you should jam the flop is that you're always allin on any turn, but V isn't. If the turn is the flush, it's actually pretty clear for him to check fold a lot of hands. To continue on the flop you must either have had a strong hand, maybe stronger than his, or a draw, which you've now presumably hit. So anyway, if you're committed already OTF and he isn't, commit him straightaway. "High variance" isn't a criticism of a line
Edit: Oh and as played, OTT it seems pretty clear to check behind, it's hard for it to make sense to bet when the vast bulk of the pot is protected.
