South leads and cashes
A first, East can discard a small heart without problem of being
squeezed, because South can win with the
A and promote the
Q, but there is no entry to hand to cash the
Q. The proper way is to win with the
A to avoid blocking, then play small diamond towards hand's
A, now East will be squeezed in both the spade and heart suits.
