These opening bids were devised and developed by Mr. Max Odlund, (Mr. Max Ödlund), from Stockholm, Sweden, in the late 1970s. He is a World Bridge Federation member with WBF Code: SWE&500049. He is a member of the winning team for the 4th European Youth Team Championship conducted in Copenhagen, Denmark, in the year 1974. His team mates were Alvar Stenberg (npc), Peter Billgren, Kent Karlsson, Jim Nielsen, Svante Ryman, Bjorn Sanzen.

After an opening of 1 Club, a first response of 1 Diamond is considered to be negative, whereas a Major suit response shows at least a 5-card suit. A first response of 2 Clubs is game-forcing if the opening is weak, and slam-forcing if the opening is strong, which the opener must decide and direct to the correct contract. The use of opening a 4-card Major suit corresponded with the Acol bidding system.
