Then you can introduce the notion of certain tricks which we will define like this:
We will apply this definition quickly to the hand that they have just played and write it on the board; the children must suggest normally a total of five or six certain tricks in North/South, the error of five coming from the fact that they may only see three tricks in Hearts.
