What actually happened, my partner doubled, passed to me. Our agreement says that any double of a suit opener is for takeout. What can I do? If I pass declarer might suppose that the outstanding hearts are in my hand, and be somewhat annoyed when they turn out not to be. How can I bid 3NT with no stop in hearts?
I ventured 4♦ which was passed, though I saw my partner visibly wince. And managed ten tricks fairly easily for the loss of three trump tricks.
3NT is cold, also probably 5♣. One table even managed 4♠+2 for a top. And to rub it in, 3♥X is an 1100 penalty! Afterwards, discussing with partner, we came up with the idea of double of 3-openers being 'optional', partner can pass for penalties if they have nothing to bid. But on this hand I think North should have bid 3NT, rather than X, despite the singleton ♦.
Suggestions?
