3 folds, Villain calls, SB calls, <font color="#cc0000">Hero raises to $1.50</font>, Villain calls, SB folds.

Flop: 7[img]/images/graemlins/heart.gif[/img] 9[img]/images/graemlins/heart.gif[/img] T[img]/images/graemlins/club.gif[/img] ($3.25, 2 players)

Villain has flopitis and is 72/13 through 85 hands. His winnings have been coming from tussles with a 66/5 at the table. Villain is very aggressive post-flop, but hasn't yet shown down a hand he put in a raise postflop.

What action to take in this sort of situation is probably very standard for everyone on this forum, but I'm not yet comfortable.

What does villain's insta-mashing the raise pot button mean? Did villain hit this flop hard? Is shoving the right play here? Can I fold QQ?
