Landy

Landy is a convention for use after the opponents have opened 1NT. A 2 overcall shows at least 5-4 in the major suits and 10+ points. The point count minimum may be relaxed at favorable vulnerability. On the flip side, extra strength is needed for a 5-4 overcall because of the slightly decreased chance of a fit.

Some examples of hands suitable for a Landy overcall:

KQT82 A9854 A53 —

KJT9 KQ432 A74 5

Q9732 KQ8765 T 7

AJ872 AQT4 53 92

The responses to a Landy 2 overcall are as follows.

Response	Meaning
2	Artificial, showing equal length in the majors. Partner is requested to correct to 2 or 2.
2	Natural, signoff.
2	Natural, signoff.
2NT	Artificial and forcing for one round. May or may not have major-suit support. Shows 12+ points and asks partner to clarify his hand. (See below.)
3	10-12 points with 4-card support. Invitational to game.
3	10-12 points with 4-card support. Invitational to game.

Approaches vary after partner makes a forcing 2NT inquiry. Here is a sensible structure from "Bridge Conventions in Depth" by Matt and Pam Granovetter. Minor suit rebids show different types of 5-4 hands, while the majors and 3NT all show 5-5 length (or better).

Overcaller's Rebid	Meaning
3	Medium strength with 5-4 or 4-5 majors. Partner has the option of rebidding 3 to ask for the 5-card major.
3	Maximum strength with 5-4 or 4-5 majors.
3	Minimum strength with 5-5 majors.
3	Medium strength with 5-5 majors.
3NT	Maximum strength with 5-5 majors.

Per the Granovetters, your definition of "minimum", "medium" and "maximum" strength will vary depending on how aggressively you use Landy. A rough guideline is:

• Minimum - 6 to a bad 10 points
• Medium - 10 to a bad 12 points
• Maximum - 12+ points

If the 2 overcall is doubled, then partner's conventional responses are:

Response	Meaning
Pass	Natural and non-forcing. Shows 5+ clubs.
Redouble	Artificial and forcing, showing equal length in both majors. This is alertable! Partner is expected to pick a major.
2	Natural and non-forcing. Shows 5+ diamonds.
2	Natural, signoff.
2	Natural, signoff.
