On the play of the last spade, West and North let go clubs, and
East is squeezed. Pitching a heart yields an immediate trick in
that suit, but if a diamond is pitched declarer follows with Ace
and 3 of diamonds. If East wins the trick, they must lead hearts
conceding the last two tricks there. If west saves partner by
playing the king of diamonds on the 2nd diamond trick, then they
must concede the last two tricks to dummy's now high Ace of
clubs and Jack of diamonds.
