TRICK 1.--Many players would be tempted to lead the supporting
diamond rather than to open the four-card suit.
TRICK 2.--Should B lead the ace of spades the ruff would be
established in the weak hand. As B holds protection in all of the
suits, his best play is to lead trumps through the strong hand.
TRICK 3.--It would be bad play for A to return his partner’s lead of
trumps. He holds the king of trumps protected and must wait until his
partner can again lead through the dealer’s hand. It would be wrong
to continue his original lead of spades, as the dealer could then
stop the lead of trumps and give dummy the ruff. A infers from his
partner’s lead of trumps that he holds strength in the other suits,
and the ten of diamonds is undoubtedly his best play.
TRICK 4.--B again leads through the strong trump hand, A makes his
king and leads his losing trump to draw two for one. No matter how
the dealer may play he cannot prevent his adversaries from making the
remaining tricks in spades or in diamonds, it being impossible to
obtain the lead in dummy.
