This hand comes from a $22 rebuy on Pokerstars. About a third of the field remains, you have T20,000, which is about average. Button has T16,800. Blinds are 300/600. No reads on button --- Hero is new to table, and has never played against the button player before.

UTG, hero raises to 1600 (I am intentionally not revealing hero's cards), all fold except the button. The flop comes KT4 rainbow. Hero bets 2400, button minraises to 4800.

What hands do you think button does this with? As hero, with which hands would you 1) raise all-in, 2) flat call?
