Landy

Devised by expert Alvin Landy, this convention stipulates that a 2 overcall of 1NT shows at least 4-4 in the majors and 12+ points. All other overcalls of 1NT are natural, and Landy applies in both direct and balancing seat.

The responses to 2 are:

• Pass: Long, strong clubs with no interest in the majors
• 2: Long, strong diamonds with no interest in the majors
• 2/2: Signoff, although overcall is allowed to bid again.
• 2NT: 12+ points, one-round force. Partner is asked to bid a five-card major if he has one, or 3/3 to show the respective minor-suit stopper with 4-4 in the majors.
• 3/3: Invitational
