TRICK 1.--To win the game Z must establish and make the club
suit; as A holds both queen and jack of clubs, he must make one trick.
TRICK 2.--A plays very badly in attempting to win this
trick. This mistake, however, is often made. Should A refuse to win
this trick it would be impossible for the clubs in Y’s hand to make.
TRICK 9.--B’s only hope is to find his partner strong in
spades.
