You have two choices.

[Jeff W]

You raise in the CO with 55. A typical player reraises you from the SB and the BB folds.

You have two and only two choices:

1. Cap pre flop and bet any flop when checked to. After you bet the flop, you are free to play the hand as you wish.

2. Call pre flop and raise any flop if he bets. After you raise the flop, you are free to play the hand as you wish.
