Instructions: Click on the link (the number of a deal) and after the movie appears, click on “Next” to have the opening lead. You can then click on “Play” and play the hand for yourself or by following my notes.
East leads the 10 of clubs, going to the Jack and Ace.
You win the club return, and say you next win the Ace, then the Queen of diamonds, only to discover four diamonds and hence a diamond stopper with East.
Win three heart tricks and the King of diamonds.
East discards a spade, then a good club, in order to protect his King of spades and the diamond stopper.
Throw East in with a diamond.
East can win his two club tricks, but is now forced to lead a spade up to the Ace-Queen.
On this deal you must plan the entire play before deciding where to win the first trick.
To give yourself any chance you must establish the long clubs.
Since this will require several entries to your hand, it is clear to win the diamond lead with dummy’s King.
Say that after a club to the 9 and 10, South switches to a heart.
Win with the Ace and ruff a club.
All follow to the Ace and King of trumps and continuing towards your goal, you ruff another club.
A diamond to the Ace allows you to lead a fourth round of clubs.
South produces the last club, you ruff in dummy, happy to see that North cannot overruff.
A third round of diamonds to the Queen leaving you in your hand.
The hard work done!
Lead the established club.
South has to ruff to prevent this card becoming your tenth trick and dummy’s 9 of trumps is promoted as your tenth trick.
You have 12 tricks, which means that the count is already rectified.
A thirteenth trick will be there if spades break 3-3.
However, if spades don’t break, a defender can be squeezed if he has the long spades.
The threat cards are the C9 and the S3.
Note that both threat cards are in North’s hand.
As you need at least one threat card to be in the upper hand, you can squeeze here only West.
Note also that the 3 of spades is (going to be in the course of the play) one-card threat and the A-9 of clubs represented the two-card threat (a threat card combined with an honor that provides an entry).
Remember also that the squeeze card must lie in the hand opposite the two-card threat.
Draw trumps, cash the three top spades (discovering the 4-2 break), the diamonds, and the rest of the trumps.
When you play the last trump (the squeeze card), all you need to do is to watch for the appearance of either black ten.
If the ten of spades appears, discard the nine of clubs from dummy.
If the ten of clubs appears, discard your last spade.
Now you can notice the role of the two-card threat.
If you were to play the Ace of clubs prematurely, you would have not be able to reach the 9 at the end.
When a contract seems secure, you should think what might possibly go wrong.
Even though (as you are about to discover) trumps are 3-1, there will be no problem if a high heart is not ruffed, since dummy’s ruffing trump is a high one.
When you draw a second round of trumps and discover that South holds the missing trump, you should play to neutralize the effect of the ruff of a high heart.
The correct play is to cash one high heart and lead a diamond to dummy in order to lead a heart through South.
If South ruffs, you follow low, and later ruff your remaining low heart in dummy.
If South discards, you safely win your second-high heart and ruff a heart loser in dummy.
There are two main chances for the contract: a 3-3 club split, and a spade finesse.
If the spades are tried first and the finesse loses, there will probably be only a tiny chance to make the slam. .
But if the clubs are tried first, you have an extra chance.
You should draw trumps while ruffing dummy’s low heart.
Then as you try to run clubs and after East shows up with four clubs, you can lead a fourth round from dummy, discarding a losing spade.
When East wins this trick, he is endplayed: he must lead into the spade A-Q, or concede a ruff-and-discard.
Say South begins with two top clubs and switches to the Queen of spades.
Suppose you win, play a diamond to the Ace, and exit with a spade.
South will win and will obviously switch to a trump.
Now you will be unable to ruff your spade loser, and furthermore the King of diamonds will be unreachable.
You will be one down, losing two clubs and two spades.
A duck on the lead of the Queen of spades will present the defenders with a dilemma that they cannot overcome.
If South plays a trump, the Ace of spades will later be an entry for the King of diamonds;
If South knocks out the Ace of spades, you will be able to organize a ruff of the third round of spades.
