Often, when the opponent has opened 1NT, you will
want to bid but will have a two-suited hand. Indeed,
it is often the extra playing strength provided by
the second suit that makes your hand worth a bid in
the first place.
To
cater for this sort of hand, some partnerships play
that an overcall of 2§
shows this sort of hand: similar strength to an
overcall in a suit but with both major suits. This
is known as the Landy convention. It enables
a player with a two-suited hand in the majors to
compete more easily. The drawback is that you no
longer have available a natural overcall of 2§.
On
balance it is worth this concession, as a player
overcalling on the strength of a good minor suit may
well find himself outbid anyway if the opening side
have effective competitive methods. It is more
useful to be able to overcall showing both majors
than to have a natural 2§
bid available over 1NT.
Using this Landy convention, an overcall of 2§
shows:
Other overcalls (and a double) retain their natural
meaning.

Responding to a Landy 2§
overcall
With
a fit in one of partner’s major suits, responder
should simply bid the suit that he prefers. With
enough values to invite game (about an opening hand)
responder jumps to 3 of the preferred major, and on
a stronger hand he could jump straight to game.
With
no fit, responder may bid 2NT (invitational) or,
with values for game, 3§
over the conventional 2§
(forcing).
When
responding to partner’s Landy overcall, remember
that queens and jacks in the minor suits are often
not worth much as partner is likely to be short in
the suit. Aces (and, to a lesser extent, kings) are
good cards.
