On opening lead, <span style=color:#f00>follow Suit with encouraging signal
attack K</span>\C<span style=color:#f00> in dummy</span>.

West leads A\D, East follows with Q\D. As J\Dand 9\D control the  10\D in
dummy, the Q\D can be played as an encouraging signal. 

The Q\D promises the jack (or the queen is singleton). 

If West leads a small diamond at trick two, East wins the diamond and seeing
the weakness in dummy should lead J\D. 

Without that defence, 2\S wins a trick as a club is thrown on dummy’s hearts.

South leads 4\S. North wins A\S and returns 7\S (the vital signal card). 

East can’t have four spades after the 2\C reply to Stayman, so South can tell
that North started with three spades. 

South must duck 7\S, keeping K\S as an entry to cash the spade winners. 

If North had returned 2\S, South would win K\S, as North must have four spades.

<span style=color:#f00>Follow partner’s lead with count signal</span>

North leads K\D. South follows suit with 9\D, to show an even number of cards.
This also denies holding the J\D.

West protects diamonds by ducking the first trick. North must abandon diamonds
because a second diamond lead will give West an extra trick. 

A spade is a safe switch. 

South has 6\D to play when winning with A\C and 3NT goes one down.

<span style=color:#f00>Suit Preference (McKenney) Lead</span>

East leads A\S and West encourages with 10\S, hoping to trump the third trick.
East continues with K\S. The lead to the third trick is 9\S, a suit preference
signal for a diamond return to be won by the A\D. 

If East held A\C, East would lead 2\S for partner to ruff. 

West trumps with 6\H and plays 8\D (2nd highest to indicate no  honour) to
East’s A•. 

East wins with A\D. Then East can lead his fourth spade and West’s trump beats
dummy’s 5\H.

<span style=color:#f00>Discard to show suit preference</span>

East leads A\C. West follows with count signal 3\C. When East leads K\C to the
second trick, West follows with 6\C. This confirms that West started with three
clubs. Dummy started with three clubs, so declarer started with three clubs.
East leads Q\C to the third trick and sees all the other clubs fall. East leads
4\C to the fourth trick and looks for a suit preference discard from West.

West signals for a spade. If the pair have agreed High to Encourage and Low to
Discourage, a discard of 8\S gives the message.

East leads a spade and the defence take the fifth trick.}

<span style=color:#f00>King / Ace Doubleton</span>

West leads the KING of spades. East follows with 3\S (a discouraging card). 

When West plays A\S, it shows West has AK doubleton. At trick three, West leads
a club, won by dummy’s Q\C. 

When Declarer plays a heart. The J\H is best as a deceptive card, but East must
rise with the A\H and give West the spade ruff.

South leads 10\D, won by dummy’s K\D. 

West plays 2\S to Q\S and A\S and a second trump, won by North’s king. 

North has a choice of plays. Lead a diamond for South to ruff or lead 9\H
through declarer? Which is best? 

If South played high-low in trumps to show three spades and so still has a
trump, North will play a diamond.

{

<span style=color:#f00>A suit preference discard</span>

East leads 7\H, to the 3\H, 10\H, and A\H. 

North leads a trump. East wins A\S and West signals with 10\D, asking for a
diamond (playing high to encourage). 

East should play 6\D through dummy’s \DKJ. West is lucky to have a high
diamond. Not so good if East had \DAQ32, but maybe Q\H discard would be taken
as suit preference for diamonds. 

South should play three rounds of clubs, throwing a diamond from dummy, before
playing trumps, then 4\S is unbeatable.
