.10/.20 villain insta open pushes the river

I have only been at the table for 2 or 3 orbits and villain hasn't done anything out of the ordinary. I'm obviously most interested in the river but comments on all streets please.

Holdem No Limit - $0.2 BB

UTG ($87.43)
MP ($31.39)
CO ($11.15)
Button ($39.48) [Hero]
SB ($17.48)
BB ($19.98)

Hero is Button with T, Q
Preflop: (6 players, $0.3)
3 folds, Hero calls $0.20 and raises $0.50, SB folds, BB calls $0.50

Flop: 9, 8, 6 (2 players, $1.5)
BB checks, Hero bets $1, BB calls $1

Turn: Q (2 players, $3.5)
BB checks, Hero bets $2, BB calls $2

River: 7 (2 players, $7.5)
BB bets $16.28 and is All-In, Hero?

Note that he pushes INSTANTLY. So I suppose the question is, does he have JT?

If he does have JT, he screwed it up by not raising the turn - pot is too small and 2 clubs are out. EDIT.

I guess for this to be a call he has to have no T (45/56) almost as often as he has JT. You are mostly playing for $3.75 (half of current pot).

Sorry, I don't follow what you're saying.

I think he's saying if villain wants to stab this excitedly at a $3.75 pot, let him have it. You'll have the nuts next time.

Zen, hero holds Tc.
