I apologize in advance for this personal set of deals this week from last year's Senior Trials, but most of them show my teammates in a good light rather than me.

Here is one example. In this deal I played three no-trump after introducing my clubs as a passed hand. I received the lead of the heart five and decided to rise with the ace in case East won the heart king and shifted to a spade, which I thought could set up too many winners for the defenders.

I cashed the diamond ace at trick two to find exceedingly bad news. Hoping for the best, I ran the club queen, which held, then led out the diamond 10 to West’s queen. Back came a heart to West’s king, and the defenders cleared hearts, leaving me with just eight tricks. Although there was no legitimate play for nine tricks, this looked like a depressing result, but fortunately I had teammates to help me out.

In the other room South opened three clubs and North used Blackwood, driving to slam. East, Arnie Fisher, found a Lightner double for the diamond lead, and South (in need of a swing) redoubled. West, Fred Hamilton obediently led a diamond, and Fisher ruffed and returned a trump. Declarer went up with the ace and cleared the trumps, but still had to lose a trick in the majors for a penalty of 1000 and a gain for our team of 14 IMPs.

The U.S. Bridge Federation is running its trials this week to select the team for the 2012 Olympiad Tournament. To mark the occasion, I shall be running a few deals from last year's event, in which my team qualified for the Senior Bowl in Veldhoven.

In today’s deal my partner, Dan Morse (East), opened one spade and I raised to two spades over the one-no-trump overcall, and played there. Against two spades, the defenders accurately led a heart, but ducked their diamond ace. So Dan was able to get a heart loser away on the club ace and hold his losers to two trumps and one in each red-suit, for plus 140.

In the other room the auction went as shown, with Arnie Fisher competing over two spades with two no-trump, and Fred Hamilton moving on to game. The defenders led a spade to the ace and returned the suit. Hamilton knocked out the heart ace, won the third spade, and led the club king from hand. Once he had guessed clubs, the defenders had just one trick in each suit, and Hamilton had nine tricks.

Did you notice the defenders’ slip? At trick one East must put in the spade jack, then win the heart ace to return a low spade. Now West will win his club ace and play the third spade to East, who can cash out for down one. (And had East ducked the heart ace smoothly, might declarer have — fatally — switched his attention to clubs?)

Today's deal sees South in a delicate no-trump slam, having carefully avoided the pitfall of playing six hearts, where the defenders can crossruff the first five tricks. Against six no-trump West finds the passive heart lead and declarer has 10 top winners. He can establish a spade trick easily enough, but if he assumes West has all the high spades, he will need to create an endplay or a squeeze for the 12th trick.

Most simple squeezes involve trying to take the rest of the tricks, but where, as here, one trick has to be lost after pressure is applied, the position is often more difficult to see.

The first step in the process is easy enough. Declarer cashes four rounds of hearts, then sets out on the clubs. West can discard two spades on the hearts without discomfort. However, the four rounds of clubs do put West under pressure. He lets go two spades early, then a painful diamond, but in the six-card ending, he has three diamonds and three spades left. What should he do now? Since a spade is obviously fatal, West must hope his partner has the diamond jack, so let’s go a diamond.

Now declarer cashes the diamond ace and king, reducing West down to his three spades. Declarer then leads a spade to his king, which West must win and lead a spade away from his jack. Declarer runs the spade around to his hand and has the rest of the tricks.

Bridge is a strange game. Why on earth would it be easier to make four hearts in today's deal than four spades? If you do fall by accident into four hearts, you would ruff the club lead, cash the heart ace, then run the spades. That way you simply give up the three trump tricks to West. But in the real world, you will play four spades.

You ruff the top club lead, then take the spade ace and king. If trumps split, you will find it easy to make 11 tricks, but when trumps divide 3-1, it would be very easy, but fatal, to draw a third round of trumps.

If you do that, then play ace and another heart, West will win and tap you for a second time with another club, and again when he gets in with the third heart. You are now out of trumps and can never score your fifth heart.

Instead, you must play ace and another heart before playing a third trump. If hearts break, you can ruff the next club and draw the last trump before playing a third heart. But if hearts also break badly, you can ruff the second club, give up a heart, ruff a third club, and ruff the fourth heart in dummy.

East can overruff for the defenders’ third trick, but the contract still succeeds — since you have only winners left, together with one trump.

Today's deal saw North produce a slightly aggressive raise to three hearts after his partner's simple rebid of hearts. The fact that the opponents had not supported spades did suggest that his partner would have length there — which made the action rather less attractive than it might appear. At teams or rubber bridge when vulnerable, the action is not unreasonable, but at pairs it is important in positions of this sort to protect the plus score.

When West opted for a passive club lead rather than an aggressive diamond lead, it tipped declarer off to the idea of rejecting the finesse. So South went up with the club ace and decided to set up the spades in the process of ruffing out the suit.

At trick two he passed the spade nine around to West, who won cheaply and shifted to the trump seven. South won the king in dummy, crossed to hand with the diamond ace, and led out the spade king, covered by the ace and ruffed.

At this point declarer could ruff a club back to hand, draw all the trumps, and give up a spade to the queen. That left him with the master spade eight for his 10th trick. In all, he lost two spades and one diamond.

The defenders could have defeated the game with an initial trump lead. And had West led the diamond jack, declarer might well have misguessed the play by taking an early club finesse — which would not have been a success!

In six spades, after winning the club queen in dummy, you should cash the trump ace. If trumps are 5-0, you will need the hearts to be 3-2 on most layouts. As a result you will cash the heart ace and king and ruff a heart with the trump queen before returning to hand with a trump to play on hearts. All you will lose is a trump.

When both opponents follow to the first round of trump, it would be a mistake to draw a second round. If you do, you no longer have the entries to establish the hearts when both majors are 4-1.

So, cash the heart ace, then lead a low heart to the next trick. If instead you try to cash the heart king, East will ruff and the contract will fail. (When East returns a trump, you cannot then ruff two hearts and draw East’s last trump, so you will have to concede a heart trick to West.)

But when you correctly play a low heart at trick three, what can the defense do? You can win a minor-suit shift and return to hand with a trump to ruff a low heart with dummy’s queen. Then, since there will still be a trump remaining in dummy, you can draw the remaining trump ending in hand and follow by running the hearts. You will make four trumps, four hearts, a heart ruff and the three minor-suit winners.

In the deal that follows, Joann Sprung found a fine defensive play that so deceived declarer that he wound up going down four tricks instead of scoring up overtricks in his no-trump game. The deal comes from the first qualifying session of the 1993 Life Master Pairs. Sprung's partner was her husband, Dan.

Joann led her top heart, and dummy’s jack held the trick. Declarer now led to his heart ace and led a club, no doubt intending to insert the nine, a play that would have enabled him to make his contract if East took his king. This is declarer’s best play in the suit. West is far more likely to have a holding such as Q-10-x or K-10-x than she is to have K-Q-x.

However, on the first round of clubs, Joann played the queen! Declarer decided to duck, and Joann led another heart, captured by dummy’s king. Declarer now led a spade to his jack and Joann’s king, and she led the diamond king, ducked. She switched to a spade, and Dan won his ace and cashed his good heart.

Next came a diamond to declarer’s ace, and South continued to go after clubs — but this time Joann played the 10! Declarer could have minimized his losses by winning the ace, but he inserted the jack and was chagrined to see the king come up on his right. Dan switched to a diamond, and Joann took two diamond winners before being forced to give declarer the last trick with her last club to his ace.

One recurring theme of the first World Mind Sports Games was the difference that the opening lead could make to the outcome of a contract. For example, here's a deal from the Women's match between England and Poland.

In the first room, Nicola Smith, East for England, opened one club and South overcalled one heart. North-South explored further, then settled in three hearts. Sally Brock led her singleton diamond; Smith took her ace and returned the diamond nine, suit preference for spades. Brock ruffed, returned a spade, and received another diamond ruff. Another spade return completed a perfect defense that saw the contract one down from the get-go.

In the other room the auction went as shown, with Catherine Draper as North sensibly evaluating her diamond fit and aces to be worth a shot at game, once she found her partner with length in both red suits.

West looked no further than the club king for her opening salvo. Anne Rosen won in dummy, drew trump, knocked out the diamond ace, discarded a spade on dummy’s fifth diamond, and claimed 10 tricks.

Should West have read more into the accelerated bidding after diamonds were mentioned? West has five points and her partner has opened the bidding. The simple arithmetic means that North and South are unlikely to have the normal number of high cards usually associated with a major-suit game. The inference is that they have found a second fit, and the diamond ruff may therefore be critical to defeat the game.
