1a. How many points does opener have? >12+ points<

1b. How many diamonds does opener have? >4 diamonds<

1c. How many clubs does opener have? >5 clubs<

1d. What possible distributions does opener have? >Opener must have 4 diamonds and 5 clubs with the remaining 4 cards in the majors. With 6+ clubs opener would re-bid clubs before showing the diamond suit. If opener was 5-5 in diamonds and clubs, opener would open 1 diamond rather than 1 club. Furthermore, opener must have at least one card in each major. Otherwise, opener would have either 4 spades or 4 hearts with a void in the other major and would bid the major before bidding 2 diamonds. Therefore, opener's distribution must be either 1-3-4-5, 3-1-4-5, or 2-2-4-5.<
