An example auction would be helpful.
Here is a typical sequence where I am having problems (with one pair in our club):
1
♥ is artificial, just showing a balanced hands without 4-card majors, 12+ HCP;
1
♠ is also artificial, showing either a negative (0-5) or a limit hand (about 9-11), any shape;
1NT is to play in front the a negative and balanced responder (if the weak responder has a 5+card suit, he will have the means to place the contract there).
How many points does opener have at his point? The lower limit is still 12, but he may be as strong as 20 HCP. In fact he may be even stronger. With a flat 22-count like AQx AQx AQxx KJxx, he may well judge that even if partner contribute with some 4-5 HCP, prospects for game in notrump would be poor. My opponents would like to hear me name explicitly the upper limit of opener's hand. I don't bother about that upper limit, and our convention card doesn't specify it. This problem regards exclusively the opener. If 1NT comes to an opponent in the protective position, he disposes of all the information he is entitled to about opener's hand.
Say reponder doesn't pass but bids 2
♦ instead, showing 5+ diamonds and 24-28 ZAR points (about 9-11 HCP). If opener raises to 3D, I explain this as invitational, but again my opponents want to hear the number of his HCPs. This time I find it even more difficulty in determining that number, for he may aim at the notrump game (satisfied to play in a 4
♦ partial with an unstopped major) as well as at game in diamonds (e.g. holding four or five trumps and a small doubleton). I repeat, I feel somewhat uneasy in having to speculate about what shows a bid which is in reality a requirement given to partner:
- I order you to pass if 0-5 balanced (1NT)
- Pass with a minimum, go ahead with a maximum (3♦)
