Rules for Leading Low Cards. If the suit selected for the lead contains none of the combinations from which a high card should be led, it is customary with good players to begin with the 4th-best, counting from the top of the suit. This is called the card of uniformity; because it indicates to the partner that there are remaining in the leader’s hand exactly three cards higher than the one led. From any of the following combinations the proper lead would be the Four:—
Rules for Leading Short Suits. It will sometimes happen that the only four-card suit in the leader’s hand will be trumps, which it is not desirable to lead. In such cases, if there is no high-card combination in any of the short suits, it is usual to lead the highest card, unless it is an Ace or King. Many good players will not lead the Queen from a three card suit, unless it is accompanied by the Jack. All such leads are called forced, and are intended to assist the partner, by playing cards which may strengthen him, although of no use to the leader. The best card should be led from any such combinations as the following:—
All these rules for leading apply equally to any position at the table when a player opens his own suit for the first time.
Rules for Leading Second Round. On the second round of any suit, the player holding the best card should play it; or having several equally the best, one of them. If he is Fourth Hand, he may be able to win the trick more cheaply.
If the original leader has several cards, equally the best, such as A Q J remaining after having led the King, he should continue with the lowest card that will win the trick. This should be an indication to his partner that the card led is as good as the best, and that therefore the leader must have the intermediate cards.
