{East's opening lead is a choice from two four-card suits:\n
In spades a “second” of \S8 shows a suit without honours.\n
In clubs a “fourth” of \C5 shows a suit with at least one honour.\n
However, the clubs have a large “gap” from \CA to \C10.\n
Perhaps leading an un-bid major is the better choice.

West wins the first trick with \SQ. Playing \SK and \SA establishes partner’s
last spade.\n
West now must choose which of the other three suits to lead. The honours in
hearts and diamonds in dummy suggest that a club lead may be the best choice to
find a winner in partner's hand.}

{West has no attractive opening lead. The least worst is \SA at least honestly

East should signal an even number of cards by playing high-low, \S8 followed by
\S5. This tells West to play all three honours which establishes East’s fourth
spade.

After winning \SAKQ, West must choose a lead from the other three suits. Dummy
has little strength in diamonds and clubs, so declarer is probably strong in
those suits. It may be better to lead "through strength" in hearts to find
values in partner's hand.

East can now take two heart tricks, a winning spade and later \CA and \H3 to
take the contract two down.}

is very weak in diamonds and clubs, so declarer is probably strong in those

Eventually the defence may win four more tricks, \DK, \CA, a heart, and the
established spade, to defeat the contract.}

win \SA, \SK, \SQ to defeat the contract.}

When defenders see the long diamond suit in dummy, they can also see that there
is no "entry" to dummy in the other three suits. Declarer will want the defence
to play \DA early to be able to win four diamond tricks in dummy. West must not
play \DA on the first round of diamonds. East should should play \D2 to show
partner a holding of three cards in diamonds. West then knows that declarer
started with only two diamonds so \DA can be played on the second round of
diamonds.

After winning \DA, West can switch to \S7 and now the contract will be defeated.}

{North has an awkward lead. The only four-card suit is hearts but they are so
poor so that any lead will look like a fourth highest and will disappoint
partner. The spades are lovely, but short. Perhaps best to lead \SA to have a
look at dummy and a signal from partner.

Dummy has four spades and South plays \S6, the lowest possible card suggesting
a holding of three spades. Dummy is weak in hearts and diamonds so declarer is
probably strong in those suits. Perhaps leading \C10 may find South with some
values in clubs. South wins the trick with \CQ and returns a spade to North's
\SQ. North can then lead \C9 for South to win the trick with \CK. South can
then lead \C2 to force out \CA from dummy.

Eventually the defence can win further tricks with \DA, \SK, \HA, and \C8 to
take the contract two down.}
