When North jumped to four diamonds, systematically showing a balanced slam try in support of hearts, South rejected the try. But after he showed only one key-card, his partner next made a slightly optimistic grand slam try, promising all the key-cards. With all the kings and a little extra shape, South decided he had enough to go for the brass ring.

West had a suitably passive lead against seven hearts in the form of the diamond 10. Declarer needed to decide which would be the master hand, and in which hand he would take ruffs. Sensibly, he decided to take ruffs in dummy, so he wib the diamond ace and carefully drew two rounds of trumps with dummy’s high hearts.

When the heart ace-jack revealed the bad break, South understood that it might be difficult to take the one ruff he needed in dummy. But he found the best line when he cashed the club ace-queen. He then crossed back to hand by leading a spade to the king, pitched dummy’s remaining diamond on the club king, and ruffed a diamond in dummy. He could next lead a heart to his hand, draw the last trump, and claim the rest.

Players tend to assume that any line that needs two favorable breaks will generally require more luck than a line that needs just one. But here declarer played a line that needed very little from both minor suits (East having at least three clubs and two diamonds) as opposed to that player having three or more diamonds. South’s chance of losing to a ruff on his chosen line was relatively small by comparison to the risk of encountering a 5-2 diamond break.

Opinions vary as to whether South should bid diamonds or spades here in response to one club. With less than an invitation, you might prefer to respond one spade; the problem with auctions where you bid diamonds is that opener must then either bid a major if he has one (which makes it hard to get to clubs with confidence) or rebid one no-trump if balanced. In the latter scenario, you might miss a 4-4 major-suit fit.

Here, in a teams game, South reached three no-trump on the lead of the spade seven to the king and ace. East figured the auction had marked declarer with both missing spade honors, so he found the threatening shift to the heart 10. What would you have done as South after West contributed the jack to this trick?

Declarer could see that ducking might leave him behind in the race to five tricks, after a club shift by West. So, he took the trick and ducked a diamond, with West winning his jack to return a heart.

Declarer now resisted the temptation to win and play on diamonds — in case one defender had four diamonds and four hearts. Ducking the heart would at worst cost the overtrick, but today it left West unable to continue the suit. West shifted to a club, which declarer won in dummy, remaining vigilant. He led a second diamond from dummy, and even though East tempted him by following with the queen, he ducked again. Now he had three tricks in diamonds and two in each of the other suits.

The British home international open series is the Camrose Trophy. From the English Camrose pretrials a few years ago, John Froztega played this hand very nicely; but it was Marc Smith, the injured party in the East seat, who generously reported it. Given perfect defense, it is hard to believe that any of the four or more top tricks that East-West have against four hearts could get away!

Peter Czerniewski as West had done well for his side, up to a point, by not sacrificing in four spades, which would probably have gone at least two down. Instead, he passed out four hearts and led a low spade, and dummy’s nine held. A heart to the jack exposed the 4-0 break, and there seem to be at least two inevitable losers in each red suit.

Still, Froztega did not give up hope; he set about playing a cross-ruff in the black suits. He cashed the club king and ace and ruffed a club, then took the spade ace and ruffed another club. When he then ruffed a spade, he had reached a five-card ending with three diamonds and two hearts in each hand.

Now came a diamond exit to the king and ace. Czerniewski could cash one more diamond to let Smith discard his club, but then had to lead either a spade or a diamond, which Smith was forced to ruff at trick 11. That in turn required him to lead away from the heart king into dummy’s trump tenace, to concede 10 tricks. Remarkably, the defense’s sure trump winners had completely vanished.

Today’s deal shows a type of problem that is often encountered in real life. It is necessary to plan the play right from the start in order to visualize the ending.

As South, when you take advantage of the vulnerability to open one spade, you hear West overcall in hearts. North drives to game showing short hearts, and you wrap up the bidding in game.

When dummy comes down, you can see that you are certainly high enough. West kicks off with the heart king and shifts to the spade jack. You must now plan how to reach 10 tricks. The obvious line to follow is a cross-ruff, but be careful! The key is that you must win the trump shift in hand to ensure that your cross-ruff will not be interrupted by an over-ruff.

Your plan will be to ruff one heart low and two hearts high in dummy, while crossing back to hand with two club ruffs. Specifically, you win the spade ace and ruff a heart low, then cash the club ace and cross-ruff the next four tricks.

After taking seven tricks in a row, declarer can cash the diamond ace and exit from hand with a diamond. In theory, either defender can win the diamond, but in today’s three-card ending, declarer will be able to score both his 10 and eight of trumps in hand for his 10 tricks, no matter what the defenders do.

Note that if West had an original 2-6-2-3 shape with the spade nine and diamond king, he would win the trick with his king, but would only be able to lead hearts or a trump, so declarer would still be safe.

North’s jump to two no-trump is the Jacoby convention, showing game-forcing values with a real spade fit. In essence, North promises an opening bid and four or more trumps, although with an unbalanced hand including a singleton and trump support, he might jump directly to the four-level in his shortage, a splinter bid. South has minimum values and no shortage, so he shows this by bidding game at once. While other methods may be more effective, this has the virtue of simplicity, if nothing else.

After the initial club lead, declarer ducks (hoping the defenders will not shift to diamonds and put him on the spot). As hoped, the defense continue clubs, and South wins the ace at the second trick.

Next, he draws two rounds of trumps, ending in hand, and leads a heart to the queen and king. Back comes a heart; declarer wins the ace and ruffs a heart. Finally, declarer ruffs a club to dummy and a heart to hand, leaving himself with the diamond guess for his contract. Is it a blind guess, or can South tilt the odds in his favor?

All he has to do is to count the hand: The way the plays in clubs have worked out so far, he can reasonably assume East has the heart king and the king-queen of clubs. But he passed in first seat, so he cannot hold the diamond ace or he would have opened the bidding.

Thus, the correct play is to lead a diamond toward the king, intending to put up that card if West plays low.

The USA under-21 team lost to Sweden in the finals of the 2014 World Youth Bridge Championships held in Istanbul. The gold medalists included three players who have already represented their country and won medals in the European championships open and women’s sections! Among the Swedish players were Ida Grönkvist and Mikael and Ola Rimstedt, all of whom won the junior title two years later, and who will be stars at world level sooner rather than later.

The USA silver medalists included Ben Kristensen, who played with Kevin Rosenberg. The latter is the son of Michael and Debbie Rosenberg, both world champions. Their teammates were Christopher Huber and Oren Kriegel.

Today’s deal came up in the final. In the first room, the Swedish East (probably rashly) sacrificed in five diamonds at his second turn to speak. This decision seems unsound because he was too balanced in the side suits, and he was not bereft of defense. This was passed around to the USA North, who doubled and collected 500.

In the second room, the auction was as shown: East (Huber for USA) bid just four diamonds. This passed to the Swedish North, who bid four hearts.

Kriegel, West, led the diamond ace, and on seeing dummy’s singleton, tabled the only card at trick two that could lead to the defeat of the contract — the club jack — a textbook surround play to ensure three club tricks for his side, whichever club declarer played from dummy.

The player with the South cards was looking forward to opening two no-trump when his reverie was interrupted by East’s pre-emptive two hearts. At this point, South’s options were a clumsy leap to three no-trump, which might miss a spade fit, or the more delicate approach that he followed at the table, of doubling and converting his partner’s constructive three-club call to three no-trump.

(Many people play that calls of three of a minor are constructive here, since they use a bid of two no-trump as Lebensohl, a puppet to three clubs if the overcaller does not have significant extras.)

West led the heart five, and South, ever suspicious, ducked the first heart, won the next as West reluctantly pitched a spade, and then had to decide how to play the rest of the hand. A reasonable approach would be to play for 3-3 clubs, but if you cash the top clubs, cross to the diamond ace and test clubs, you will almost be out of chances if they do not break.

South inferred from West’s reluctance to part with a spade that he had started with no more than four cards in that suit and a singleton heart, so a distribution of 4-1-4-4 seemed likely. Thus, South made a very thoughtful play when he cashed the club king and overtook the queen with the ace. When the 10 dropped, he could lead the club nine and establish four tricks in clubs to go with his five plain-suit winners, making nine in all.

After North’s Jacoby two-no-trump call, promising four-card spade support, South started cue-bidding, asked for key-cards, then confirmed that the partnership had them all by bidding five no-trump. When North showed the club king, South bid what he thought he could make.

West led the heart 10, and declarer counted 12 winners (five spades, four hearts, and three minor-suit tricks). If spades were no worse than 3-1, he could draw trumps and discard a diamond from dummy on the fourth round of hearts; then dummy would be able to take a diamond ruff.

Declarer played low from dummy at trick one, winning his jack in hand. Next, he carefully played a high trump from hand. When West discarded a diamond, declarer could see that trying to ruff a diamond was too dangerous a policy to pursue. Instead, he decided to ruff two clubs in hand without using the heart ace as an entry. He cashed the club ace and king, then ruffed a club low when East followed suit. Next, he led the trump queen to dummy’s ace and ruffed dummy’s last club with the jack. His remaining trump, the five, went to dummy’s nine. After drawing East’s last trump with the 10, declarer claimed thirteen tricks: four trumps, four hearts, a diamond, two clubs and two club ruffs.

Note that the bad heart break means that if declarer had been prodigal with his trump entries (by playing a low trump toward dummy at trick two), he would have gone down.
