TRICK 1.--B’s play of the queen denies the jack, which A marks with
the dealer.
TRICK 2.--The dealer can lead his high spades, but this lead might
establish a trick in the suit for his adversaries. His best play is
to conceal the strength in this suit, and to establish the club suit.
TRICK 3.--A is placed in a difficult position; if he continues with
his diamonds the jack will make. He must place the lead with B so
that the dealer’s hand may be led through. The heart suit is better
than the spade suit, as dummy holds an honour to lead through.
TRICK 4.--B must wait until his partner can again lead through the
king of hearts, and so returns A’s original lead.
Should A continue with the lead of diamonds at trick two the dealer
would win four odd tricks instead of losing that number.
