Many will not play Ace Second Hand in any case, and will play the Queen with the first combination only when they are weak in trumps. The reason for this exception is the importance of retaining command of the adverse suit as long as possible.
On the Second Round, the Second Hand should follow the usual rule for playing the best of the suit if he holds it; or one of the second and third best, if he holds them. He should also be careful to estimate, by the eleven rule, how many cards are out against the leader, which will sometimes guide him to a good finesse. For instance: first player leads Ace, then Eight. If the Second Hand holds K J 9 2, instead of playing the best card to the second round, which would be King, he should finesse the Nine.
With Short Suits. When Second Hand holds such short-suit combinations as:—
and a small card is led, his proper play is one of the high cards, because he cannot save both of them.
On Strengthening Cards Led. This is a difficult point for the beginner, and his best plan is to follow the rules already given for covering cards higher than the Ten. One of the most common errors is to cover a Jack led with a Queen, when holding A Q and others. The Ace should be put on invariably. To play the Queen in such a position is called finessing against yourself.
Singly Guarded Honours. Many players put on the King Second Hand, if they hold only one small card with it, and a small card is led. This will win the trick as often as it will lose it; but it betrays the hand to the adversary, and enables him to finesse deeply if the suit is returned. It may be done in order to get the lead, and in trumps the practice is very common, and generally right. With Queen and only one small card, it can be demonstrated that it is useless to play the Queen Second Hand, except as an experiment, or to get the lead in desperate cases.
With any combination weaker than J 10 x, it is useless to attempt to win the trick Second Hand, and only makes it difficult for the partner to place the cards correctly.
