JAZZ BRIDGE 17 NEW BRIDGE SYSTEM BASED ON AN UPDATED STRONG CLUB SYSTEM by Eugeen Vannuten Jazz Bridge 17 1 Jazz Bridge 17 WHAT ? CHARACTERISTICS JAZZ BRIDGE is based upon strong clubs, ref. Precision : all (strong) hands from 16+hp onwards go via 1♣. JAZZ BRIDGE aims to address as much as possible all The other 1-level openings cover the hands with a 12-15hp distributions and in the meantime to make bidding difficult for range or according the Rule of 20 or according to ZAR's opponents. 26+ zps. JAZZ BRIDGE uses the 1NT weak opening , 12-15hp, indicating The added value of strong clubs systems lies more in the all balanced hands without 4 card major. Opponents have to limitation of the other 1 -level openings rather than in enter the auction on the 2 level. ♣ the strength of the 1 opening itself. The 2-level openings are mainly preemptive although we JAZZ BRIDGE is also a modular system : only the one-level give 2♣/♦ a multi-touch to show possibly a very strong , openings are interrelated and are mutually impacted if one of balanced hand. them changes. The 2 and 3 level openings can be filled JAZZ BRIDGE is a FIVE-card based system. 1♥/♠ therefore according to own taste with preferences for preemptiveness promises at least a 5 card. The 1♦- opening can be balanced with a 4 card major or unbalanced with or without a 4 card major. The "weak" 1NT-opening (12-15hp) is done with a balanced hand without a 4 card major and with or without a five card minor. Jazz Bridge 17 2 Preface Some say one can divide the bridge world into 2 groups : those who keep on playing the bridge system they have learned and It became a rough and difficult journey with a lot of pittfalls, those who are a bit more critical and often ask themselves if accidents and lessons learned. Both engineers realize the unique context of their journey : 2 brothers with the same interests in this things can not be improved. One thing is sure: the "perfect" mind game, together in the same car in long traffic cues towards bridge system does not exist. The existing systems are as good as their work giving long discussing hours. you apply them. Mainly you can reach in any system - if well applied - the correct game contract . Differences might occur in Convinced about the added values of the multi - principle ( more finding optimal part score contracts and slams. than one handtype in a single bid) and about the transfer-principle This paper is meant for those advanced bridgers who are "open" (announcing a suit by bidding just below that suit) , it was logical to baptise the new system as MUTOS : MUlti and Transfer Oriented for new ideas and who dare to leave old dogma's on a road of System. creative thinking. Convinced that one does not has to be a bridge world champion The starting point was Strong Clubs , related to Precision. Between to be able to think about and question existing bridge systems, that starting point and the current presented version, the brothers the brothers Vannuten started years ago a challinging trip in the have created and defined 5 to 6 playable systems that all have been world of bridge systems hoping to find an optimal mix and to thoroughly tested out. After a deep evaluation, end 2007, the 1 construct a tool that enables bridgers to bid as much as possible opening was rewritten in such a way that little was left from the original concept. MUTOS has arrived in an ending phase.... The end given hands leading to the correct contract. This led to a new of a journey. modular bridge system where existing conventions were screened and new ones were created, tested and tuned. In 2010 an improvement was introduced into the 1♦ opening, with These ‘system-engineers’ learned on their way that simplicity is a great impact on the 1♦ handling and also on the 1NT-opening. Also a very important value and so constantly a balance has been new strategy for partners weak hands was elaborated what led searched between theory and practice : the bridger must be able basicly to a new system, that we baptized as JAZZ. to reconstruct at the table the answering scheme's supported by Eventually, bridge is not an easy thing to read about and to acquire : algorithms and patterns, making the system manageable for the it is and remains a mind game where every situation, every sequence own side and difficult to follow by the opponents . of events, every card is important. Take your time, reread paragraphs, open your mind and an exciting new world can open . The book ( Dutch) and this site were made in a modest way to enable others to enjoy the result.

Zar Petkov himself : Never miss a game again. Zarpoints = sum of two longest suits + difference between longest suit and shortest suit + honneurspoints+ 2per ace + 1 per king Having read the paper of mr. Petkov, how do we map this on Jazz17? open 1♦/♥/♠ from 26 zarpunten onwards (zp). If you have sufficient hp-strength , just open accordingly. The zar-count comes in handy in border cases where you search for a justification to open (where others may pass). We open (the strong) 1♣ from 32 zp onwards. Partner answers 1♦ with 8-19 zarpoints. From 20 zp onwards you (32+20=52) you make the bidding game forcing. This also means that with a lousy 16hp hand like HB108 VB75 AVB Vx, where before we would open with 1♣ , we now should open with 1♦ (Zar 29). apply the preëmptive openings ( 2x/3x) with 22-25 zarpoints. The simple message is " I do not have 26zp" . We experienced that reading these pages when using zp's is rather difficult. To preserve the readability we keep on using the Milton-counting. Nevertheless the zar-counting remains valid and is a good instrument to validate hands with distribution power and control cards. We apply following agreement : Level Opening Strength zp Milton hp Rule of 1 1♦/♥/♠/ZT 26-31 12-15 20 1♣ 32+ 16+ 25 2-3 2-3-4x 22-25 6-11 <20 Correlation Zar en Milton Jazz Bridge 17 6 Strategy General common sense 1♣- NEOSQUEEZE Bridge is about scoring either by finding and Brings all hands from 16+hp onwards or equal via making the best paid contract, either by a special distribution : Zarpoints 32+ zps. making the opponents to score less.
