  • Update to Jorj Club System
    Jorj Club system ♠♥♦♣ George Cuppaidge 2014 Re-edited in Nov 2014. A new feature enables users to distinguish between a 6-9 point, and a 10-12 point response to 1C, at the one-level when balanced, or at the level of two of the suit with 5+cards it. See 3.1. This complements the system’s means of distinguishing a 6-9 point 3-card raise of 1D, 1H or 1S from a 10-12 point raise, below the level of two of the suit. 1.0 Introduction. This is a five-card major system. It is a relay system but the natural framework means it can be played without relay continuations. This system is virtually convention free. It is directed at bidding the hand you hold. Logically, it is impossible to do better than that. The opening bids are limited both in strength and in the shapes they may contain. The range of pass is 0-9 points. Whether you are locked in a part-score battle or searching for a key queen for that grand slam, you will outdo your standard- playing opponents consistently. You will know more about what is going on than they do. The system enables you to find exact hand-shape, without which really accurate slam bidding is impossible. Three-suiters and 45+shapes, which are ignored in standard bidding, are bid with certainty in this system. The system strong bid is 1NT. This is the opening bid for all 20+point hands. It will be seen that the single extra step, compared to the more common 2C, makes bidding easier and more accurate.

  • Four Card Majors: Western Natural Updated
    Foreword It is easy to dismiss Marvin French as a crank or a curmudgeon or as the contrarian that he certainly was but this does not do justice to the man’s life. Marvin was Life Master 10231 achieving the rank in 1956, “when it was hard” as he liked to say. This was not a boast, just a fact not well understood by many who started playing later, particularly after the great masterpoint inflation that kicked off shortly into the new millennium. Marvin was a force on the west coast bridge scene. Local San Diego Diamond LM, Anne Terry, never one to withhold an opinion positive or negative, called Marvin the “best of the best.” D22 Director, Ken Monzingo said, “Like him or not, he was a unique man. A leader, not a follower. A brilliant man of honesty and integrity.” Marvin made significant contributions to bridge literature and less known contributions to bidding theory. He was a contributor to Bridge World, Popular Bridge (published in the 1960s and 1970s), and the D22 Contract Bridge Forum, and editor for the latter prior to Joel Hoersch. For many years Marvin maintained his own website where he posted his writings on bridge, blackjack, and literature. His 90 page Squeeze Refresher (For Good Players) is undoubtedly the best reference that is available for free. Sometime in 2011 I got to know Marvin better because we started exchanging e-mail on various bridge topics in part because I had been reading his website and had taken some interest in his discussion of four card vs.

  • Mellon Diamond
    Mellon Diamond Adam Meyerson and Noble Shore November 12, 2003 1 General Principles The Recursive Diamond is a precision-like system, featuring light limited open- ings, weak notrumps, and an artificial forcing bid (1♦). In contrast to precision and many other systems, the focus is on accurate game and partscore bidding rather than finding slams. We tend to enter the auction aggressively on distri- butional hands and our methods emphasize exploring for the best fit rather than setting up an early game force. Our defensive bidding methods similarly em- phasize finding our best fit, showing many types of two-suited hands as quickly as possible. The opening structure of recursive diamond is as follows: 2NT at least 5-5 in the minors, weak (typically 7-10 hcp) 2♥ ♠ weak two 2♣ ♦ intermediate, rule of 20 opener, 6+ cards in bid suit 1NT 10-12 if 1st/2nd NV, else 12-14, can include 5-card major 1♥ ♠ 5 card major, rule of 18 opener, not 5332 shape 1♦ any 16+ hcp; 17+ if balanced and not 1st/2nd seat NV 1♣ 11-16 hcp, balanced or three suiter or minors Bids of 3♣ and above are standard preempts. We frequently preempt three of a minor on reasonable six-card suits, but other three-level preempts are almost always seven. 2 Major Suit Openings Major suit openings at the one level promise five cards in the bid suit. We will treat any 5332 hand with a five card major as balanced, and open in the corresponding notrump range (1NT or 1♣ or 1♦).

  • The Mini Roman Convention
    The Mini Roman Convention By Neil H. Timm In a large number of deals, one can expect the suit pattern 4-4-4-1 to occur about 3% of the time and the specific hand pattern 4=4=4=1 (four spades, four hearts, four diamond, and one club) to occur about 1.8% percent of the time. And, one can expect the pattern 5=4=x=x (exactly five hearts and four spades) to occur about 1.5% of the time. While these values appear to be small, the hands are often difficult to bid. For this reason, special bids have been devised to describe them. For the three-suited pattern, the bid is called Mini Roman. Mini Roman – Three suited hands The origin of the Mini Roman 2♦* bid is unknown, though it is widely played among the masses. When playing Mini Roman, we give up the weak two diamond bid. There is no standard way to play Mini-Roman. We review two commonly used approaches. However, the first question you may ask is why play it? (1) It is preemptive and allows you to steal part-score hands, (2) you are aware of the hand distribution quickly, and (3) it allows the opener to bid four card suits. Mini Roman with four spades Mini Roman uses the bid of 2♦* to describe a hand with exactly the distribution 4=4=4=1 with 11-15 HCP. With a weak hand (0-9 HCP) and 3+ spades, partner bids two spades, to play. With invitational values (10+HCP), responder bids 2NT to ask for the singleton suit.
