Hi Jane! This lesson is quite fast for me but could expound on what is the mathematics behind the number 11 you mentioned? Thanks, Sanjeev

[@janestearns9936]

Hi Sanjeev, gosh, maths never my strong point! All I can tell you is that if your partner leads the 4th highest, or if you are declarer and you know the opening lead is the 4th highest - the rule of 11 is a mathematical certainty. Take the face value of the card away from 11 - and in the dummy and 2 remaining hands you will have the number of cards larger than the face card. So if the face card is a 5 - take 5 from 11. There are 6 cards out between the remaining three hands higher than the 5. So see how many of the 6 you can see in dummy, see how many you can see in your own hand - you now know how many higher than the 5 are sitting in the remaining unseen hand. Hope that helps - but if you want the science behind it - you need to ask a mathematician - or a better player than me! Good Luck!

@@janestearns9936 it is 11 because there are 13 cards in a suit, 1 is the card laid down and the ace is high. So if card is 5, only 6, 7, 8, 9, 10, J, Q, K and A are higher. 3 are in the lead hand (if fourth lowest). 6 left. Which is 11-5. Count higher cards in dummy and your hand then you know what's remaining and can play accordingly.
