The loser count is one too high

Phyllis Diller said, "Aim high, and you won't shoot your foot off."

In many bridge deals played with a trump suit, declarer finds that his loser count is too high. He must find some way to eliminate those he cannot afford. Two common ways of doing that are ruffing a loser in the shorter trump hand, or discarding a loser on a side-suit winner in the other hand. In this deal, though, South must find a different method. How should he play in four hearts after West leads the spade queen?

South could see one loser in each suit. He had just nine winners: two spades, five hearts, one diamond and one club. The only realistic chance for a 10th winner was to find East with the diamond king. But that would require two dummy entries: the first to lead toward declarer's diamond queen, the second to reach the diamond ace after unblocking the diamond queen. Where are those two entries?
