Playing the weak hand

Villain has been taking a beating and is on super tilt. Last hand he got called AI PF by 85o and lost with 9 or 10 high. I took about $40 from him playing HU beforehand.

What is the minimum you call with here?

Seat 3: K_collie ($10 in chips)
Seat 4: Infamous9 ($107.92 in chips)
Seat 5: DonGotti ($28.50 in chips)
K_collie: posts small blind $0.15
Infamous9: posts big blind $0.25
----- HOLE CARDS -----
dealt to Infamous9 [8h Kc]
DonGotti: folds
K_collie: raises to $10 and is all-in
Infamous9:

i think thats close, else your getting nth leveled

If he's pushing with any two I'll call because K8o is an abover-average hand heads-up.

zomg RJG in seat 5. Call if you like money.
