So here is the situation.

PokerStars No-Limit Hold'em, $0.10 BB (9 handed) -

MP1 ($19.45)
MP2 ($11.05)
MP3 ($10)
CO ($13.15)
Button ($5)
SB ($10.50)
Hero (BB) ($10)
UTG ($15.30)
UTG+1 ($11.20)

Preflop: Hero is BB with QcQd
4 folds, MP3 bets $0.30, 3 folds, Hero raises to $0.80, MP3 raises to $2.20, Hero calls $1.40

Flop: ($4.45) Ac, 2h, 9h (2 players)
Hero checks, MP3 bets $1.80, Hero ????

Villain is a reg, I see him around the tables all the time. He is a typical TAG player. I don't think he is 4 betting lite, I put him on JJ+ and AK. Even tho the flop bet looked kinda weak, I didn't want to come over the top and try to steal. Interested to see what you guys would do in this spot.
