sentences:  No matter how South continues, the defense continues to force South with heart leads after taking the K and the A, again winning two spades, a diamond and a club, or a trick in each suit.Notice also that West must wait for the third round of spades to take his A, after which dummy is out of trumps.If he takes his A on either the first or second round of trumps, South can play on the minor suits and ruff a fourth round of hearts "in dummy".
