Q: 1 - What will you lead against 6NT?

South	West	North	East
-	-	-	2♣

A: ♠10. A top spade is the least likely lead to give away a trick. This was the deal:

♠ Q 2

♥ J 10 4

♦ 9 8 7 2

♣ A J 9 4

♠ K J 5 4

♥ 9 7 6 3

♦ K 6 5 3

♣ 8

♠ 10 9 7 6 3

♥ 8 5 2

♦ 4

♣ 10 7 6 2

♠ A 8

♥ A K Q

♦ A Q J 10

♣ K Q 5 3

Take the East cards now. You play the ♠Q from dummy and are not surprised when this is covered by the king. You win with the ace. How will you continue the play?

You may need to take the diamond finesse three times. This can be done only if you have three club entries to the dummy. Cash the ♣K first, all following, then overtake the ♣Q with the ♣A. When North shows out, you can finesse once in diamonds, finesse the ♣9, finesse diamonds again, return to the ♣J and finesse diamonds for the third time. Slam made!

Your 2♣ showed both majors. West's 3♣ was natural and forcing.

A: ♥4. You should lead from the better major, and there is no good reason to lead the King. This was the deal:

♠ 10 5

♥ 10 9 3

♦ 9 8 6

♣ A K Q 3 2

♠ J 8 6

♥ J 8 6

♦ J 10 4 2

♥ K Q 7 4 2

♦ K 3

♣ 8

♠ A K 4

♥ A 5

♦ A Q 7 5

♣ 9 7 6 4

Take the East cards. South leads the ♥4, North playing the jack. How will you play the contract?

You should win the second round of hearts. When you play the ♣A K, South shows out on the second round. What can you do? (If you continue with the ♣Q, you will have to win the fourth round in your hand and will go down.)

You must lead dummy's last heart, throwing a blocking club from your hand! Whatever the defenders return, you can cross to the ♣Q and score dummy's two small clubs.

A: ♥10. Sometimes it is beneficial to lead fourth-best from this heart holding, gaining when partner holds a doubleton honor. Since you have no side entry, that cannot be the case here, and you should lead the 10. This was the deal:

♠ 7 5 2

♥ A K

♦ Q J 6 5 2

♣ 6 5 2

♠ K Q 8

♥ 8 5 2

♦ K 10 8 3

♣ Q 10 7

♠ J 6 4 3

♥ Q 10 9 6 3

♦

♣ J 9 8 3

♠ A 10 9

♥ J 7 4

♦ A 9 7 4

♣ A K 4

The ♥10 is led. Take the East cards now. How would you play the contract?

Four diamond tricks will bring your total to nine. A safety play will bring in these tricks, whichever defender holds four diamonds. You cross to a club honor and lead a low diamond towards the dummy. Here, South will show out and dummy's queen goes to North's King. You win the next heart, finesse the ♦9, and play the ace and jack. You are then in dummy to cash the fifth diamond.

Q: 4 - What will you lead against 4♠ here?

Partner's raise to 3♥ was pre-emptive.

A: ♦A. You lead your singleton, hoping that you can reach partner's hand for a diamond ruff. This was the deal:

♠ 10 8

♥ K 8 4 2

♦ 10 8 6

♣ A 8 7 2

♠ 7

♥ Q 7 6 5

♦ 9 5 4 3 2

♠ A Q J 9 6 4 2

♦ K Q J 7

♣ 4 3

On the ♦A, your partner plays the ♦2. What will you do next?

Partner's ♦2 is suit preference, suggesting a club switch. Your next card is the ♣10. Take the East hand now. How will you try to make 4♠ after this start?

If you play low, North will win and give his partner a diamond ruff. You will subsequently lose a trump trick to the King and go one down. Better is to win with the ♣A and lead the ♥K, discarding your remaining club. This play is known as a Scissors Coup. You cannot then suffer a diamond ruff and will make your game.

Q: 5 - What will you lead against 3NT here?

South	West	North	East
-	-	-	1NT
Pass	3NT	All Pass

A: ♥4. Of course you must lead from your five-card suit. This is the very best length to attack from in no-trumps. When you have a six-card suit, partner is likely to hold a singleton. This was the deal:

♠ K 9 7

♥ 5 3

♦ J 8 7

♣ A J 10 9 6

♠ Q 6 5 3

♥ 10 9 7

♦ K 6 2

♣ K Q 8

♠ 4 2

♥ A J 8 4 2

♦ 9 5 4 3

♣ 7 2

♠ A J 10 8

♥ K Q 6

♦ A Q 10

♣ 5 4 3

Now take the East cards. How would you play 3NT when the ♥4 is led to North's 9?

You should win with an honor. North is now the 'danger hand' who could lead through your remaining heart holding. At trick two, you make the key play - the ♠J to the ♠A. Next, you run the ♦J, which wins. Your next move is to run the ♠9 (which is possible only because you unblocked the ♠J earlier). Four spades, one heart, three diamonds and one club give you the game.
