Question 20b.

You chose to play the 6 of Clubs, saving your Queen for later. This is understandable, but will not really help as it means that the opposition will win this trick by using only one honour. While if you had put your Queen on, it would have forced them to use up 2 honours, so they would then have only 1 left, and you will also have your protected Ten left. Go back and choose again from Question 20.
