Hand 1 Dlr. North Vul: None
(1) Not a game force.
West leads the 2. When you play low from dummy, East wins the jack and continues with the A and a spade to West’s K. At trick four West leads the 13th spade and East ruffs with the queen. Plan the play from here.
Hand 2. Dlr. East, Vul: Both
West leads the 2. You win the ace in dummy and play your other black ace, East discarding a club. Plan the play from here.
