This is a variation of the Polish Club bidding system and was devised by Mr. Greg Matula of Warsaw, Poland. The opening of 1 Club could describe one of four different shapes and distributions, which would be clarified in the ensuing auction. The illustration below of his publication from the year 1994, ISBN-10: 91-87416-15-8 contains additional information. This publication was reviewed by The Bridge World in the August issue, page 28, of the year 1994.

Note: In the year 1963, a series of bridge articles appeared in the Polish bridge magazine Brydz with the outline of a national bidding system, based on a nebulous 1 Club opening bid. It was called the Polish Club. Polish bridge players and readers of these articles enjoyed them to the extent that they put the ideas of the concept into practice at the bridge table.

Note: These particular bridge articles continued until the year 1966 with the addition of new information, new modifications, and adjustments for particular bidding sequences. The result was a defined and refined Polish Club bidding system. Mr. Greg Matula, a leading and expert bridge player, was a key component in compiling and complementing these articles and the modifications, and who finally produced in the year 1994 a publication called The Polish Club, which presented in its entirety the foundation for the entire concept and the accompanying explanations.

Note: Any additional information, especially photographs, as to the bridge personality of Mr. Greg Matula would be greatly appreciated.


This bidding system also includes a strong 1 No Trump opening, whereas the 2 No Trump opening describes a two-suited opening in both Minor suits. Weak Two openings describe distributional holdings, one of which is the suit mentioned.

These opening bids are shown in the schematic below. Source.
