The perfect river card for me... (and my bluff) ?

[benneh]

No reads, this is pretty early in the stars 30+3 deepstack tourney.

After i'm min-raised on the turn, it's pretty clear there's no way i can win this pot at a showdown unless villain isn't very good, which i have noidea. I get the feeling he's raising a flush and not something like 2 pair or a set, but who knows. Comments on my river play? it's a low cost (relatively) attempt to win a big pot, but is it still chip spewing?
