Roy opened the bidding with one club, the opponents passed throughout. Kai responded one diamond, Roy jumped to two no trump. Kai bid three diamond, which is check back stayman, after Roy's reply of three no trump. Kai reasoned that partner must have useful cards for the small diamond slam and jumped to six diamond. At the other table the opponents stopped at three no trump and 10 imps to Canada.
