Conventions and tips
INVERTED MINORS

I'm sure all would agree that it's vital to understand and learn your basic system before adding exotic conventions. That said, conventions can allow you to refine your bidding. We thought it would be a good idea to make notes available of the more widely used conventions that people are interested in. Do ask me about others and we'll try to put them up too.

Someone asked about Inverted Minors recently so that's what we've started off with!

If your partner opens 1♦ andyou hold 14 HCPs and a longish ♦ suit you may find yourself in a dilemma if youare unable to bid another suit or NTs. With standard ACOL, we would probablymanufacture a bid of, say, 2♣ (10+ pts, unlimited & forcing) and wait forpartner's response.

 

A useful convention to copewith this situation is "Inverted minors" which reverses the meaning of our 2♦and 3♦ responses.

 

Ptr                   you

1♦        -           3♦                    6-9 pts

1♦        -           2♦                    10+ pts unlimited, FORCING, denies4 card major

Opener then bids his cheapest suit with a stop in - trying to get to3NT.

 

AFTER OVERCALL

1♦        1♠        a) 2♦               6-9pts            unchanged

                        b) 2♠               10+ pts           forcing

                        c) 3♦                2-5 pts            extra weak for maximum disruption

 

AFTER DOUBLE

1♦        X         a) 2♦               6-9pts            unchanged

                        b) 2NT            10+ pts           forcing

                        c) 3♦                2-5 pts            extra weak for maximum disruption

As with all convention there are no doubt othervariations.

 

Here are a couple ofexamples:

 

Ptr                               You

♠    3 2                        ♠   A K 2                     Bidding           1♦        -           2♦        -

♥   A K 4 2                  ♥  Q 8 7                                             2♥       -           2♠        -

♦   A J 9 5 3                ♦  K Q T 7 4                                       3NT

♣   K 7 3                     ♣  6 5

 

The 2♦ response denies a 4card major. The partnership now starts showing stops to try to get to 3NT.

 

Ptr                               You

♠    3 2                        ♠   9 5                        Bidding           1♣       X         3♣       -

♥   A K 4                     ♥   7 6 3                                            

♦   A J 9 5                   ♦   Q 8 7 4 2                                     

♣   K T 7 3                  ♣    Q 4          

 

Clearly one needs to be morecircumspect in bidding after the opposition has doubled for take out - and lookout for the vulnerability. Here you have no option than to support partners'suit anyway! The 3♣ response after the double shows a minimum 2-5 points. Ifyou feel a wee bit uncomfortable, remember you are at least bidding to thelevel of the fit.

 

Hope this helps.
