im not sure which position u are at. u said u are on the button, yet u said the button raised to 2400.
anyway, assuming u dont have money invested in the pot yet, your best move is to fold. with players behind u, and with 4800 chips, the button will have to call u relating to the pot odds
, and at best, u are up against 2 overcards, meanin a flip. worst case, up against a bigger wired pair.
why risk your chances of makin the money? wait for a better spot.
