see what your opponent minraises with. many at that limit will just minraise with any top pair. some will do it with 2 pair, a set, or even a draw. learn the player, and then take advantage of his weakness.

1 of 5 things.
have a hand and re-raise 3-4 x his bet,
have a hand and call then c/r
no hand and re-raise 3-4 x his bet,
call for good pot odds for a nut hand,
fold
