Last orbit, I raised in late position, c/b and got c/r'ed and I folded, so I think Villain may think I raise pretty light on the button..I'm pretty sure a 3 bet is in order here and since most 3 bets are going to be half his stack, what do we think about a shove?

PokerStars No-Limit Hold'em, $0.50 BB (6 handed) Hand History Converter Tool from FlopTurnRiver.com (Format: FCP)

Hero ($73.10)
SB ($49.50)
BB ($66.10)
UTG ($54)
MP ($67.30)
CO ($50.50)

Preflop: Hero is Button with K , A .
3 folds, Hero raises to $2, SB raises to $7.25, 1 fold, [color=#CC3333]Hero ?

I don't like a shovel pf here. I think I like a call especially in position. I would 3-bet or push this against the right opponent.

A read on the villain will make this play vary. As Krup said, against some villains flat call, against some 3bet/push

If we reraise its a 4 bet not a 3 bet. Very read dependent and can go both ways.
