I wonder if someone could help with this decision which is interesting but very daring. My partner had 16 pts. a void in ops D suit and support for other 3 suits. My P opened 1C and op jumped to 3D (with 7 in the suit) and op's partner suppoerted with 4D. My P then Doubles (below game level). I took it to mean a business X and passed. I had 4 spades and 5 clubs and a 3 pt. hand (DK) They made it and we went down to the depths of the 97th floor!! Should I have bid my Clubs? (which, by the way, went down one at another table) Thanks for any help if this isn't too confusing for you.
