Flopping two pair heads-up, and V calls big check-raise.

2/3/5 NL
Effect stacks $800.
Villain is a 20's Asian guy, young-looking and also has a demeanor that suggests his cardroom experience is limited. He is only 2 or 3 orbits into this game, but seems comfortable with actual game play. He is not limping, is open raising.

H's table image is probably tight aggressive, V has seen H 3-bet-squeeze pre-flop twice, once from the BB, and once as an utg limp-reraise. In the 1st hand all 4 opponents folded to the 3-bet, and in the 2nd hand 3 folds were induced.

V opens $20 on the button.
H in BB calls with QhJc.

H raises $120. (H realizes as the chips go out that he wanted to go smaller.)

H???

What should the flop check-raise amount have been... $80-$100?
QJo is a call from the BB preflop, right?
