I want to look at this hand played from my opponent's perspective.

Villain is mxiu, and has been reading a magazine and folding for the past 2 orbits or so, and finally put it down when he was dealt a hand UTG. mxiu is labelled as a standard TAG if you've been paying attention. Hero has been doing very well, quintupling his buy-in from $300-$1500 within a fairly short time. Only hand that hero has been in with mxiu is the first one that mxiu 3-bet preflop, and hero pushed all-in with TT, and mxiu called. Board came KJT93, mxiu told hero that QQ was good, saw opponent's hand, and still couldn't beat TTT either.

mxiu has about $850~ and Hero covers.

Hero is dealt As Kc in CO.

Villain (mxiu) raises to 30. MP3 calls, Hero calls, SB calls.

Flop: Ad Ks 2c (Pot: $125)

SB checks, Villain bets 70, MP3 folds, Hero calls, SB folds.

Turn: 3h (Pot: $365)

Villain bets 120, Hero raises to 240, Villain raises to 720 and is all-in. Hero...?
