Remark.—The fall of the spades (see Tricks 3, 4, and 5) shows that the three is in Y's hand.
Trick 6.
Tricks AB, 2
YZ, 4
6. Z A Y B↷
9♠ 8♣ 3♠ 5♠
Remark.—It is seldom right to continue trumps when led by the opponents; but this is an exceptional case. B plays well in drawing two trumps for one, as it is evident that if Y and Z make their trumps separately they must win the odd trick.
Trick 7.
Tricks AB, 3
YZ, 4
7. Z↷ A Y B
4♦ 7♦ 9♦ 10♦
Trick 8.
