OVER OPP'S T/O DOUBLE

New Suit Forcing:

Indicate at what level(s) you play this treatment.
If a new suit bid at the 1-level is forcing (e.g., 1 - Double - 1) check this box. If a new suit bid at the 2-level is forcing, (e.g., 1 - Double - 2 ) check this box.

Jump Shift:

Check any boxes that apply.

Forcing:

Check this box if a jump shift after the opponent's takeout double is strong and game forcing.

Inv.:

Check this box if a jump shift after the opponent's takeout double is invitational to game.

Weak:

Check this box if a jump shift after the opponent's takeout double is preemptive.

Redouble implies no fit:

Check here if you tend to raise directly with a fit and reserve redouble for non-fitting hands

2NT Over:

Define 2NT over an opponent's takeout double - do so by checking the appropriate box opposite the opening bid under the following categories: Limit+ (limit raise or better), Limit(limit raise), Weak.

Other:

Any other treatments.
