Hi In the last year my partner and I have adoped a Strong Club Unbalanced Diamond system to combine with our weak NT 5 card major. to our surprise we have had more success than expected with this system. Last night we played against a future international player and she asked what is a defence to a 1♦ opening, I had no reply, as this is a new concept I wonder what is a good defence to the 1 ♦ opening. Love to hear any suggestions, because beside dbl showing an equilvalant hand or naturl bidding, the question stumpted me. BTW I am a long way off even Regional class. Thanks in advance Conor
