DEFENSE VS NOTRUMP

This area is designed to be as flexible as possible. There are two basic columns. The first line is noted only as vs: . On this line you may label each column to indicate a NT range ( weak - strong ) or use one column for direct and the other for balance or some combination. Write the meaning of the bids in that column on the first line.

If you play each two-level call as natural, you can just circle the suit symbols. Otherwise you write alongside what that call indicates.
For example, opposite 2 you could write "At least 5-4 majors" or "Unspecified one suiter".

Dbl: On this line specify the meaning of a double in your defense to a 1NT opening.

Other: Use these 2 lines to note other defenses which were not described above. For example, negative doubles over 3-level interference.
