East has to respond to 1; with four-card support and no major to show, he does best to support in diamonds. East has 8 losers and so jumps to 3.

West can now become very excited. With a fit, his hand doubles in value – its void suit now worth its weight in gold. It is clear that diamonds are going to be the best denomination and he can therefore count losers too. Just 4 losers – that is three better than his minimum (7), which suggests bidding 6! First of all, though, he needs to check that the partnership has all the suits covered, and spades are obviously the chief worry. Cue-bidding is the solution: 4 . Once again a change of suit over a raise to the three-level is not natural, but when it takes you past 3NT it is not a game try either. West's 4  bid shows first-round control of the club suit (ace or void); he is hoping to learn that his partner has something in spades. East replies 4, which is exactly what West wanted to hear, and he closes the auction with 6.

As you can see, the LTC works just as well with minor suits as it does with major suits, but you should only use it once you have decided you are playing in a minor suit.

Here is one more type of hand where you have to judge where your minor-suit fit will take you. This time you have support for your partner's minor-suit overcall and both sides are vulnerable:

Your partner has made a vulnerable two-level overcall, so what do you expect him to hold?

Ace-jack to six in clubs and another card or two; put these expectations together with your own hand and see what you get: six club tricks; two aces and surely one more trick from your partner's cards?

There is a small risk involved, but bidding 3NT will be the long-term winning action. The important point on this hand is that, when you have a good minor-suit fit where you think the suit might be running, then your thoughts should turn to no-trumps because the rewards are so much greater.

Layout 7 shows Hand A opposite a likely partner:

Ten easy tricks on a heart lead, worth 130 points in clubs or 630 points in 3NT. As so often is the case, you make the same number of tricks in the two contracts, with no-trumps being worth so much more.

Change the West hand a little and your thoughts should be very different:

You still have a club fit, but you cannot rely on the suit running. Your opponents will knock out the ace of hearts in 3NT and take you down easily. When you do not have high-card support for partner's suit, you should aim to play in the suit contract. Here the complete auction would be:

You should bid 3 to show a good hand, since a raise in clubs is more likely to be on a weaker type of hand with distribution. However, over 4 , you simply pass and that finishes the auction. Ten tricks are easy for +130.
