Version 1: The origin of this defense method is unknown. Once the opponents have opened the bidding auction with a Multi 2 Diamonds, which normally shows one of three possible types of holdings, then the following defense method is employed.

Some Multi 2 Diamonds openings also show a fourth type of opening, namely a 4-4-4-1 distribution, so the defenders should first acquaint themselves with the version employed by their opponents.

This defense method is normally employed in the immediate position since the Multi 2 Diamonds is a forcing bid, which the partner of the opener may not pass.
