Poker Are we just stacking off here?

Forgive the formatting, I'm new to this.


In the $6/$6k guaranteed on ACR, well into the money.


Hero has 60bb, Villain has 40bb.


Villain limps utg + 1, folds to hero on button who has QQ and 4.5x's.


Sb and BB fold. Heads up.


Flop comes 4s 6s 2d


Villain checks, hero bets 1/2 pot, Villain calls.


Turn is Jh.


Villain checks, hero bets 1/2 pot, Villain shoves.


Hero ???



So is this a spot in which we just have to stack off presuming he has spades, some 57s and 77-99, maybe TT in his hand?


Is this close and always read dependent? I use a HUD but this player was new to the table and his SS stats were typical for the $6 level. Very small winner over 450 games or so with a $9 abi.
