Take the West hand below for the first Lesson Deal:
The dealer on your right opens 1. The auction is shown in the top right as indicated.
We'll start you with a very easy question. What is your call? Ha-ha.
After your incredible decision to Pass, North raises to 2, your partner overcalls 2 (as shown) and South jumps to 4 and everyone passes.
Think it over and decide what to lead.
This is the full deal:
After your (correct) low spade lead, dummy will play low and your partner will win the J.
At trick 2, what will East play?
After East's high spade takes the second trick, what would he do at Trick 3?
Try to cash the third spade trick.
So, what is the conclusion?
Any lead on this deal would have worked.
Any spade lead would have worked.
West had to lead a low spade.
