It is advisable to lead trumps from strength in comparatively few
hands, for the reason that the lead indicates to the dealer the
position of the trump strength held against him. If, however, you
hold four or five trumps without an honour, and combinations in the
plain suits from which you do not wish to lead, the trump may be led
through the strong hand. This is especially true of a four-trump
hand, which contains three cards of each of the other suits.
Avoid opening the trump from strength when you hold a single honour,
or even two honours. You will gain, by waiting for the lead to come
to you.
