Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. In bridge, the rule of 11 is applied when the opening lead is the fourth best from the defender''s suit. By subtracting the rank of the card led from 11, a defender can figure out how many cards are higher than the card partner has led. The rule works because the defender is known to have three and exactly three cards higher than the card led. When West leads the 7 East applies the rule of 11. This shows that there are 4 cards higher than the 7 that dummy, declarer and East holds. East can see four cards higher than the 7: The Q8 on the board and the AT in his hand. Knowing that declarer does not have any cards above the 7 (As out of the 4 cards east, dummy and declarer have, all 4 are in possession of declarer and east himself, leaving none for the declarer), if the dummy covers with the 8, East knows he can win the trick cheaply with the 10.
