Quick summary

If you are balanced-ish, leave it in NT

3NT if you have 19 HCP
2NT with 16-19 ("inviting")
pass with 15 or fewer

If you are unbalanced, a part score from a minor match at a low level is the most likely outcome, but a game can sometimes be found in Hearts or NT.

Don't leave it in 1NT if very unbalanced.

Question 1

South is obviously going to open with Hearts. What possible rebids could he have ?

Question 1

South is obviously going to open with Hearts. What possible rebids could he have ?

Answer

Well, South has a 5-4 distribution in the Majors, and 14 HCP. Nice. The apparently obvious re-bid would be his 4-card Major, however with fewer than 16HCP South should not go through his "barrier" - limiting any rebid to no higher than 2 Hearts. Bidding higher than that, his partner would put him with 16+HCP, and all sorts of overbidding might occur! So 2 Spades cannot be his re-bid.
It will have to be rebid of Hearts. But that would promise a 6-card suit - or a very strong 5-card suit, which is questionable in this case.
The only other alternative is to open a weak 1NT - which I quite like, as it's possibly the "smallest lie" you can tell your sensible, stable and understanding partner. At least the extra doubleton has 2 honours! Some people though would go for the Heart opening bid and re-bid.

Question 2

Why doesn't North tell his partner about his longest suits ? With only 6 points, why doesn't he pass ?

Question 2

Why doesn't North tell his partner about his longest suits ? With only 6 points, why doesn't he pass ?

Answer

After the opening bid of 1 Heart, he would need to go to the 2-level to mention his minor suit, Clubs. But with only 7 HC points, he is too weak to change suit at the 2 level. You need about 10 HCP really. Also, he is too short to support Hearts, and he cannot switch to Spades with only 2 of them. The only bid left is 1NT, which he should bid just in case his partner is on maximum 18 or 19 HCP..... we wouldn't want to miss a game.

Question 3

Why does South leave it in 1NT, given that his Hearts are so good ?

Question 3

Why does South leave it in 1NT, given that his Hearts are so good ?

Answer

He knows his partner might only have 6 points, and 9 at the most, so game is not on, since we are well shy of 25. We've got good Hearts, but we don't have suit agreement in Hearts. We've got Spades covered, so the chances are high that our partner's limited strength is in the minors. So there are probably enough stoppers to be safe in 1NT. Probably better than 2H, where he could be short or even very short.

Unbalanced Openers rebid. Partner bid 1NT

Game in Spades most unlikely! NT ?

Your partner has nothing obvious to bid after your opening bid, but he has 6-9 HCP and needed to let you know that, so he bid 1NT.

If you're reasonably balanced, and have cover in the suits which your partner has in effect denied having, leave it at 1NT if there is no chance of game, as will generally be the case. If you're at the weak end of your promised 12-19 point range, you may in any case feel obliged to pass. If you're very unbalanced, or there's a big hole somewhere, put it back into a suit, because the opposition can be expected to exploit the hole !

If on the other hand you have 16-19 points, which can be expected in 25-30% of occasions, you should get quite excited because you may have 25 points between you:

If you're balanced and have the full 19 points, you'll probably put it into game with 3NT. If you're slightly short of 19 HCP, you'll probably bid 2NT, asking partner to raise to 3NT if he has the maximum from his promised 6-9 range.
It gets more difficult if you have an unbalanced hand. In principle you want to try to find a "game" fit in a Major or NT. So the two of you are going to have to use the remaining bidding space to search for a Major fit (a bit unlikely given the bidding), or try to convince yourselves that NT is safe. Trial bids and 4th suit forcing might both be helpful techniques to be aware of in this situation. However, a common and sensible if unexciting outcome will be a "part score" in a minor, i.e. 2 or 3 or .
