Occasions for throwing the lead arise most frequently in the end play; there are the nice situations where you gain the advantage of position by leading a losing trump or suit card.
However, situations where it is advisable to throw the lead are so frequent and varied in occurrence throughout the entire play that the subject can only be treated in a general way. Perhaps covered by one suggestion; when you cannot lead a suit advantageously, try to force the adversary to lead it to you.
THE DEALER’S PLAY OF A “NO-TRUMP” DECLARATION
As soon as the hand has been opened, make a comprehensive examination to determine the possibilities of your combined hands. Are you strong enough to win the game? Can you win the odd trick? Shall you be able to save the game?
With no other possibility in the hand, make a determined effort to save the game. If you are weak in one suit and hold the command of the suit that is opened, your danger may lie in allowing the adversaries to retain the lead.
When you hold an established suit, you cannot but gain by forcing the opponents to discard; they may unguard honours in their weaker suits or give you information that will locate high cards.
Do not forget that your strength is in your long suit, and that you are often dependent on your other high cards to establish this suit. To the mind of the novice, the loss of the lead is a calamity, and he will often lead all his high cards, leaving the command of his own suit, as well as of the others, with the adversaries.
Remember that it requires no skill to make aces and kings, and that your goal in a “no-trump” hand must be the establishment of the small cards of your long suit.
With fair possibilities in the hand, ascertain before you play a card from dummy, first: which is your longest suit; second, how can it be most advantageously led; and, third, in which hand there is the greater need of an entry card.
