Well I guess with this strong a hand but a stiff ♦, I would probably pass. Bidding with this hand is just too dangerous, besides, who can make a sensible choice of bids with this kind of hand?? A takeout double? Awful. I may do this once in a while, but not when I have a singleton (thus no support) or a void in a side suit. Picture the scene. If you double OPP's 1♣ bid and your partner has 6 or 7 diamonds, what a nice fit in diamonds, he may think. If he has enough to bid game, he would bid either 3NT or 5♦, both of them might go down if he's facing a minimum hand, but with your hand, 3NT is almost guaranteed to make, while 5♦ can hardly be made even down three. A 1NT bid? No way. If you overcall 1NT you have to promise either a stopper or a 4-card suit in ALL FOUR suits. Now you just can't assume that partner has a diamond stopper. So you have to pass. When the 1♣ bid is passed around to fourth seat, your PD can consider a 1NT balancing bid which promises only 10 points (In my system) and a balanced hand. Anyway, the correct auction is probably: West North East South 1C Pass Pass 1NT Pass 2C Pass 2D Pass 3NT All Pass
