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.
the best lesson
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

@@naomi6212 Sounds amazingly intuitive Naomi. Thank you :)
So nicely explained
Thank you!
