    First off, let's agree that we are normally looking for game in a major or 3 
    Notrump.  If we must resort to a 5 minor game contract, figure on 29
    distributional points.  So 
    when responder doesn't have a 4 card major, we should heed the warning 
    flag.  And if responder has a very short major, making a 3 Notrump game 
    looks even more threatening from responder’s perspective.  Let's see how 
    this applies to the above bidding sequence.  
    Opener has 15 HCP but it's difficult to count distributional points, 
    normally 2 more points for a 6 card suit.  Do you see why?  Notice that 
    opener's controls are in the black suits;  when promoting a suit, we can 
    readily see the problem trying to run: Q 9 8 7 x 
    x x 
    The opponents’ might run a pile of side-suit tricks before you and partner 
    can promote the minor suit.  Now let’s look at responder's holdings?  
    Looks like 7 HCP is working, particularly the nice Diamond K J honor 
    sequence.   
    But the Heart J x x and singleton Spade Q initially have 
    little value since opener isn't showing a long major.  If you are using 
    straight forward bidding, then the auction might go:  1D - 2D; 2S - 3D;
 4D - 5D
 
    While opener’s 2S rebid generally is shape showing, with this 
    particular hand 2S works well, showing extra values, controls in 
    Spades, and interest in a 3 Notrump game if partner has a Heart stopper.  
    Lacking  the Heart stopper, responder can show the apparent minor suit 
    support, bidding 4D and opener can make the final call. 
    A more advanced treatment could be used  by players that use
    Inverted Minors and  it's sister 
    convention - "Criss-Cross". 
      Those players can use Criss-Cross here:  1D - 3C;       3C = 
    Diamond support w/6-9 points3D – 4D;
 5D
 
    Here, opener realizes that responder is long in Diamonds, game is not 
    attainable without Heart controls (responder bypassed the majors). Had the 
    bidding gone 1D - 2D (Inverted Minors, game force style), the 
    partnership would know to continue bidding until game is reached.  
    A frequent stumbling block for emerging players with holdings as you've 
    shown is proper hand evaluation.  Typically responders fall in the trap of 
    counting extra points for dummy shortages, assuming the hand will be 
    valuable for ruffing.    
    Unfortunately, the recurring theme is that opener places the contract in 3 
    Notrump and the hand goes down.  Based on the bidding, reasonable defenders 
    will know to lead a Heart -- assuming opponents are 5-5 (since they didn't 
    interfere with the auction), they will take 5 Heart tricks plus 1 Diamond 
    trick. 
    In summary, finding minor suit games with distributional hands are often 
    tricky.  Hopefully this provides some food for thought. |
