These opening bids are a variant of the Symmetric Club bidding system and employs Symmetric-like relays in generally all subsequent bidding and continuances. These bids were devised by Mr. Dean Eidler and Mr. Murat Genc of New Zealand, who intended Third Seat opening requirements of 12 to 16 high card points and Fourth Seat opening requirements of 17 high car points plus.

Note: Both Mr. Dean Eidler and Mr. Murat Genc are member of the Otago Bridge Club of Dunedin, New Zealand.

These opening bids are, for all general purposes, the foundation of an individual partnership agreement based on their mutual bidding system, which gained some popularity.
