Landy convention

From Wikipedia, the free encyclopedia

Landy, named after its inventor Alvin Landy,[1] is the first of several conventional defenses created to compete against an opponent's one notrump (1NT) opening.[2] Landy is a 2 overcall of the opponents' 1NT opening to show at least four cards in each of the major suits; all other bids are natural. Requirements for the overcall vary from partnership to partnership: some require 5-5, some 5-4, and yet others only 4-4 (provided the overall strength is sufficient). The partner can take a preference to either major or make a non-forcing bid of a suit; 2NT is used as a forcing query.

Extended Landy

An extension was proposed by Ira Rubin in 1947[3] using 2 as a takeout request after a response or rebid of 1NT after a suit opening.[4] It implies more distribution and less strength than a double. It also applies in the passout seat.

Based on his initial inability to overcall the 1 opening directly, the bid of 2 by North shows five or more clubs and exactly four hearts. Similar uses were developed later by others.

Variations

[edit]

Various additional modifications to Landy have appeared over years, by various authors. The original Landy convention is deemed obsolete amongst tournament players today in favor of more advanced conventions.[5] It is still very popular at club level.

Multi-Landy

[edit]

A particular popular modification in the Netherlands is Multi-Landy,[6] a combination of Landy, the Multi 2 diamonds convention and the Muiderberg convention. In this modification, the 2 overcall is the same as in Landy, the 2 overcall shows a 6-card major suit, and 2 or 2 overcall shows five cards in that major suit and at least four cards in a minor suit.

Very similar is Reverse or Modified Cappelletti, the only difference being that the 2 overcall shows any 6-card suit, either a minor or a major.

Woolsey or Robinson

[edit]

A variant developed by Kit Woolsey and Steve Robinson uses the same responses as Multi-Landy (above) but also includes a pinpoint double. A double would show a 4-card major and a 5-card or longer minor, a constructive 6-card or longer single-suited minor, or a hand of 19 high card points or more. After 2, advancer would bid 2 to show equal length in the majors and ask overcaller to bid their better suit. After 2, advancer would respond 2 to ask overcaller to pass or correct. Advancer would bid 2 showing non-forcing values in spades but invitational values for hearts. Advancer would bid 2NT with a forcing hand asking for further description of overcallers hand. Advancer would bid 3 with invitational values in both majors. 3 or 4 are pass or correct at that level.
