Goldilocks has taken over running the weekly duplicate in the forest. She also organizes a seminar after the game, where experts can discuss the trickier deals.

Today’s hand was the subject for some discussion amongst the Three Bears. Papa Bear had declared four spades on repeated diamond leads. He ruffed the second diamond and drew four rounds of trumps, then played a club. West ducked the first and second club, and now declarer could not avoid forcing himself, so the hand fell to pieces.

By contrast, Mama Bear drew trump, it taking four rounds to do so, and during the course of this, discarded dummy’s club king and queen. She still found herself in trouble, though, as West’s club spots were fractionally too good for her. West captured the club jack with the ace and returned a diamond, ruffed by South with her last trump. But when the clubs failed to run, eight tricks was the limit of the hand.

Baby Bear appreciated that the missing clubs were more likely than not to break 4-2. He played a club to dummy at his first opportunity – which was at trick three. It would have been well against the odds to find clubs breaking 5-1 or 6-0, when the defenders could have maneuvered a ruff.

When West won the club ace and forced declarer again, declarer could draw trumps, meanwhile discarding dummy’s blocking second club. Now 10 tricks were easy. Equally, had West ducked the first club, declarer would simply have drawn trumps, discarding the club, as before.

Today’s deal sees Nicola Smith of England in the hot seat as declarer. Smith is currently the most successful woman bridge player in the world – though Jill Meyers of the US is close behind her.

East’s offbeat two diamond opening showed a weak two-bid (normally six cards) in either major. Smith’s two hearts was natural, North’s two spade bid was a cuebid showing a strong hand. In the end North closed her eyes and hoped that her partner’s hearts were good enough for slam.

When West led the spade six, it is easy to see that declarer could have succeeded easily enough by playing to ruff a spade in the dummy. However, understandably, declarer expected West would be able to ruff in on the third round of spades.

So she won the spade lead and played a trump. East correctly went in with the ace and played a second trump. Smith won in dummy, cashed the diamond ace and king, discarding a club and ruffed a diamond. She then ran off all her trump.

Her last three cards in hand were a trump, a club and the spade jack; in dummy she had two clubs and a diamond. When she cashed the last trump West had to come down to a singleton club in order to keep the master diamond; East also had to come to a singleton club in order to keep the master spade, so dummy’s club queen was sure to win trick 13. It was a classic double squeeze.

Imagine you are playing four spades here, in a team game, on the lead of the club queen. How would you plan the play?

At one table declarer saw nothing better than taking the spade finesse at trick two. East lost no time in winning and shifting to the heart queen, South covered and the defenders took their heart ruff. East could now exit in clubs, and declarer was reduced to taking the diamond finesse. When it failed, so did the contract.

However, declarer had missed a subtle extra chance for his game, and the declarer in the other room managed to spot the winning line. All South had to do was to cash his second club winner at trick two, eliminating that suit from both hands. Now when East arranged to take his heart ruff, he was firmly endplayed, since he had no trumps or hearts to lead, and a club would allow declarer to discard one diamond from dummy via the ruffsluff, and one on the fourth heart. Stripping out the clubs had completed the endplay at no cost, and this time it made the difference between success and failure.

The alternative line, of playing ace and another spade, might cost the contract if the heart queen and diamond king were wrongly placed. So even though it might succeed (and you might consider rising with the spade ace against a weak defender if you led the spade queen from hand and West ducked smoothly) it is certainly not the percentage line.

Once North splinters with four clubs he should pull in his horns at his next turn. 4-4-4-1 distribution rarely plays as well as it might be expected to. Be that as it may, against six spades West leads the trump 10. Are there any hidden traps to making 12 tricks?

Assuming that trumps are 3-2, you have 10 tricks. Two more will come from club ruffs, but you need to be careful when the full deal looks similar to the one shown below.

The opening trump lead must be won on table, with the king. Next play a club to the ace and ruff a club. Now is the time to lead a low diamond from the table. (If you take another club ruff before playing a diamond, West will win the trick and play a club. East will be able to then ruff this with the jack, and the contract will fail.)

The defense can do no better than win the first diamond and play a second round of trumps, won by dummy’s ace. After a heart to the ace for a second club ruff, you will cash the diamond ace and ruff a diamond with the eight of spades.

Art this point, after drawing West’s last trump with the queen and discarding dummy’s diamond jack, dummy will have only top hearts left. You will have taken the three top trump, four hearts, the diamond and club aces, and three ruffs in one hand or the other, for a grand total of 12 tricks.

In today’s deal you reach four hearts, after preempting to two hearts at your first turn. When dummy comes down you observe that you have nine top tricks and require a 10th. There is a very simple plan that is essentially guaranteed to produce that critical extra trick. You should rise with the club ace and draw trump ending in hand, discarding the spade four from dummy if necessary. Then lead the spade three and cover West’s card as cheaply as possible.

Suppose the full deal is similar to the one set out here. East will win the spade 10 with the queen, but what can he do next? A spade return gives you the required trick immediately. The same is true if he exits with a club into dummy’s tenace. His best hope is to try either the diamond king or queen, which you will allow to hold. At that point, even a diamond continuation is fatal for the defense.

Note that you should duck the diamond honor, in case East has ingeniously shifted to an unsupported honor. If that were the case and you won the first diamond, West would get back on lead with a diamond and could now defeat the contract by reverting to clubs.

Note; it is indeed true that your partner might have done better to bid three no-trump instead of raising to four hearts. I’m sure he will think more seriously about stealing the contract the next time this situation arises, if you miss the winning play here.

Today’s deal is from the pairs contest in Tromso at the European Open last July. It produced an excellent technical problem for the North-South declarers.

This board was played in seven no-trump at only seven of the 53 tables. Slightly to my surprise, making seven hearts would have been a considerably better than average result. Maybe the board is harder to bid than it appears?

Anyway, be that as it may, your task today is to play seven notrump from South. A spade lead may be the most awkward (because it prevents you discarding a spade from South on the hearts). So let’s give you the most challenging defense.

The correct line is to win the spade, cash one club if you like, then four (and only four) hearts, overtaking the third. When you cash the fourth (but not the fifth!) heart East is obliged to pitch diamonds – the menace he holds under South — not spades, which would produce a relatively simple double squeeze for declarer.

Beware: Cashing the last heart now would squeeze your hand. Instead you must take the diamond ace-king first; when you do this and lead the fifth heart, East must discard a spade, or the clubs will run. Now you have to bite the bullet and pitch your fourth club (never easy to do, since partner will sneer if the opponents had double-bluffed you and set it up as a winner already). When you cash off the clubs, West will be squeezed in diamonds and spades.

The field did not shine on this deal from the first day of the Tromso Mixed Teams. Only 12 of the 84 tables playing this deal reached the grand slam – and 10 went down in it! Seven pairs went down in game – one in five diamonds! That might make the result of the pairs who went down in six hearts look more acceptable. Meanwhile 30 pairs bid to the small slam, the rest contenting themselves with game. I suppose we should be happy no one played partscore…

The two tables who bid and made seven diamonds received a top club lead. They won the ace, led the spade queen to the ace and ruffed a spade. Then they unblocked in hearts and ruffed a spade with the 10. They cashed the heart ace to pitch a club, ruffed away the last spade winner with the diamond ace, and drew trump.

This line required spades to break 4-3 and diamonds no worse than 3-1, and might have survived West’s holding either the doubleton spade king or five small spades. The failure of so many pairs in the grand slam – by playing on hearts, without realizing that this line entails more luck in hearts than the winning line requires in spades – is remarkable. If you won’t stop to do the math in a grand slam when WILL you stop to think?

Only Ton Hoeyland and Maria Dam Mortensen played the grand slam correctly. They were thus rewarded, if not with glory, with something at least as important: a metaphorical ‘thumbs-up’ from this column.

The first board of the 2015 Tromso Mixed Teams saw Roy Welland drive his partner Sabine Auken to a delicate slam, and let her try to make it. I have simplified their auction. In real life a club lead would have defeated the contract, but that was not obvious to anyone during the bidding.

In six hearts Auken received the lead of the diamond five, which went to the three, the queen and her ace. She then played a heart to dummy’s jack and East’s ace. That player now returned another diamond, though even at this point a club return to dummy’s ace might still set the contract, since declarer does not yet know about the 4-1 trump split.

Anyway, after the diamond return Sabine won with the king and continued with the heart king. When East showed out, she could now continue with a club to the ace to take the heart finesse. When declarer then played off all her trumps, West was squeezed in three suits. That meant 12 tricks to declarer and 11 IMPs to Welland’s team, since his teammates defended game in the other room.

Incidentally, that declarer also received a diamond lead. His next move was to play the heart queen from hand. Now if East wins this, the heart jack is the entry for the trump finesse. If East ducks the ace, a low heart to dummy’s jack will reveal the trump split while the club ace is still in dummy as the entry to take the trump finesse and execute the same squeeze.

At Tromso last summer in the EBL Open Mixed Teams, Katrine Bertheau for the Casino Floor team found a pretty defense against her opponent’s four heart contract.

Bertheau led a spade to West’s ace and a second spade went round to the jack. Bertheau now played a third round of spades, forcing declarer to ruff in hand, in an attempt to gain control over the trump suit.

Declarer next played a diamond to the king and ran the heart queen. Bertheau correctly ducked, continuing her accurate defense, since if she had won and played a fourth spade, declarer could have ruffed in dummy to retain trump control. Declarer would have been entitled to relax when the first trump finesse succeeded, but his hopes were dashed when he continued with the heart 10 and Bertheau won to play a fourth round of spades. Since declarer was now forced to ruff in hand, West had wrested trump control from him, and established the setting trick.

That might had been a great IMP swing if Bertheau’s teammates had managed to make a game at the other table. But declarer stood no chance of making his five club contract when the heart king was offside. With spades 4-4, three no-trump was the only making game today.

For the record, it would have been possible to make four hearts on any lead with the sight of all four hands, if declarer could have avoided finessing hearts. The winning line is to cross-ruff and endplay West in trumps. But no one would find this at the table.
