BIG semibluff, thoughts?

[Mercman572]

This play is very read dependent I think, so here is the read I had. Villain is super agro and likes to make moves, stats are 60/20/3.5 after 65 hands. The other confrontation went like this:

Hero has AJ off in MP3, 1 limped to him and makes it 4BB. Button calling station calls, Villain in BB calls.

POT 3.5, Flop AA4 rainbow. BB checks, hero checks, Button Raises $1, Villain Raises 7. Hero calls, button folds.

TURN 8D 2checks (putting a 2 flush) ($18 in pot)
RIVER 6D Villain bets $6, hero calls
RESULT: Villain has 97 os

Hero calls 34.25 (All-In), CO folds.

Final Pot:

Normally i would fold here, since it looks like a small flush, trips os somehting like that. But given villains other play with no regards to an overcaller, (this time the calling station), and his tendency to make moves, I thought I wasn't sitting too badly here. My thoughts were along this line:
1. I checked a made hand vs villain only 2 or 3 hands ago, a bet might make him think I'm bluffing and he could be on what he thinks is a resteal.
2. He could be on a worse flush draw with a piece of the board
3. Its likely he may call OR fold a worse hand here, but will probably call with a hand I have crushed (KQ 1 club, etc.)
Push or fold here?
