To give your partner information.
The importance of first seeing the thirteen cards in the dummy is self-evident. The play of an entire hand is often influenced by the cards in the dummy; therefore, if you can win the first trick, you are in a better position on the second lead to play your own and your partner's hand to advantage.
These combinations should be selected in their order for the original lead without reference to the length of the suit.

As the maker, more especially if the trump is red, has shown strength, your first consideration should be to save the game. This is best done by leading your Aces and other high cards before the dealer has a chance to discard and to trump. This is particularly true when there is an established suit in the dummy hand; for then the dealer may be able to exhaust trumps and discard his own losing cards on this established suit.
