Daisy leads the
4.
Mickey should play the
2 -
second hand low -
to allow Minnie to win the trick cheaply with the
J.
If Mickey plays the
A, forgetting about second hand low,
Minnie will no longer be able to make a trick with the
J.
Of course, common sense should prevail.
When Daisy leads the
2, Mickey can see that he has all the tricks so he should step in and take them.
