What do you bid after your partner opens one no trump?
Example of a very simple bidding lesson or quiz with the main question shown in one line under the applet. This is just a simple hand I generated using my Javascript program and cut and paste over. Could be an example for begineer in Jacoby transfer for 1NT. The randomly generated 1 NT hand turns out to be an interesting playing hand.
This hand also can be use to show you how a playing sequence quiz could be. Start the hand from the beginning again. After you finish the bidding quiz. Click open the north hand. Go to play the recorded hand and complete the play. You will notice it ends at south in trick 2. What is your play. Notice the east and west hand is still hiden. This part of the software is not commercial grade but usable. I will improve it in the future.
