Any infos on villain besides his stats?
Reads? Tricky player or straightforward?
How many hands for his stats?

Without those infos:
He doesn't seem to be afraid of a flush since he's re-raising a well-sized value bet BIG. Doesn't look like a bluff to me, more like a made hand.

Since his PFR-% is 20 he seems to raise with almost any PP or big SCs.
Maybe he tripped over a flush or a set on turn/river.

Without reads: very hard to say.
