Declarer wins with dummy’s \HA and West’s high encouraging \HJ <b>signals
</b>that he has \HK.

As declarer clears trumps, East has an opportunity to use a discard <b>signal

job.

When declarer leads clubs, East can win \CA and then lead a second round of

instead his opening lead should be \S4. This <b> fourth highest lead</b> shows
partner at least four spades with at least one honour at the top.

North wins \SA and, noting the club weakness in dummy, switches to clubs

South does not play diamonds, so as to protect the K\D. South returns to the

When West plays \HQ, North knows that both South and West have no more hearts. 

East’s \HJ is now a winner, so North plays another round of hearts to be ruffed

{East leads \S4 and West’s \SQ wins the trick. West returns \S6 for East’s \SJ
to win the trick.

Now East can lead either \SK or \S8 to force out North’s \SA. Leading \SK would
be a suit preference signal for hearts whereas \S8 would show a preference for
diamonds (dummy’s clubs rule out that suit).

Without that signal West would probably lead \D10 when he wins \CK and declarer
will make the contract with 4 tricks in each of diamonds and clubs. However, if
West leads hearts East wins \HA and 2 spade tricks and the contract is one down.}

\SA and now knows that both East and South have no more spades. From the
bidding he also knows that East has at most one club.

If North leads another spade, East can simply discard his losing club to make

If North cashes \CA before leading a spade, East must ruff high and that
promotes South’s \H10 which will eventually become a trick and the contract is

because he can already see eleven diamonds, so he should signal a suit
preference for hearts by playing \D9.

Without this signal West would probably lead \CQ when he gets the lead with
\SQ.

On a \H9 heart lead by West declarer will probably win \HA but then must lose
another spade to West’s \SA. Another heart lead from West finds East’s \HK and
now East can return a diamond for West to ruff and the contract is one down.}
