It was invented by Alvin Landy.Over 1NT, the overcall of 2♣ shows both major suits, while 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.Various modifications have appeared over years, by various authors. A particular popular modification in the Netherlands is Multi-Landy, 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 a 5-card in that major suit and at least a 4-card in a minor suit.
