The dealer loses four odd tricks.
ILLUSTRATIVE HAND NO. 30
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.
