The concept makes it possible to find partner's total strength on a lower level than in all-natural systems. In the Standard version, a 2C opening is Precision, 2D is Multi, and remaining two-level openings are weak Polish two-suiters.\u003c\/p\u003e\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\u003cp\u003eOne of the key original features of the system is the concept of the artificial reverse (\"odwrotka\" in Polish), which occurs in the sequence: 1C - 1H \/ 1S - 2D - ? The convention lets players quickly find the fit in the major and determine whether the hands are worth slam investigation.\u003c\/p\u003e\u003cp\u003eThe latest version of the system, Polish Club 2020, has been devised on a questionnaire among potential users of the system. It adapts most popular treatments used in various contemporary bidding systems.\u003c\/p\u003e\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\u003cp\u003eA 1D opening is now almost always 5-carded, and the two-level opening bids are more aggressive than in earlier versions. Introducing modern conventions to uncontested and competitive auctions makes the system popular among expert players.\u003c\/p\u003e\u003cbr\u003e\u003cbr\u003e\u003cbr\u003e\u003cb\u003eAbout the Author\u003c\/b\u003e\u003cbr\u003e\u003cb\u003e\u003ci\u003eJassem, Krzysztof:\u003c\/i\u003e\u003c\/b\u003e - KRZYSZTOF JASSEM (Poland) is a well-known international player whose successes include winning the Vanderbilt Cup and a silver medal in the World Olympiad Teams.
