The old-fashioned or two-ball foursome makes a really fine and enjoyable game. It brings golfers together on even more intimate and friendly relations than usual. Partners in a foursome see very deep down into the human nature of each other. They are overwhelmingly conscious of each other's faults and weaknesses. They are enormously dependent upon each other. At the same time I do not think that even this kind of foursome is the best thing in the world for the improvement of a man's game, and I advise the young player to resist the temptation to take part in too many foursomes, to the neglect of ordinary match play in singles. For one thing, the partners, of course, only get half as much golf as they would if they were playing a round in a single match, and for another, they are too constantly anxious to play their best game. The sense of responsibility is frequently a little too much for their nerves, and you often see a man, a most dogged and persistent player in an ordinary match, who is a consistent failure in foursomes, and who in this style of game ought to be rated at six strokes higher handicap than his allowance for ordinary purposes. One feels in a foursome that one must be so very careful, and take so much extra pains, and when that feeling is uppermost in the mind while the stroke is being made, the result is often disastrous.

It is unwise to interfere unduly with a partner's system of play while a match is in progress. He may be missing his drive because his stance is wrong or his swing is faulty, but the state of affairs would probably be worse than ever if an attempt were made to put him right while the game is going on. The hint will be more useful when the match is over. And if he has a particular fancy for playing his brassy, when experience tells you that an iron club should be taken, it will not generally pay to make the suggestion at the time. The man naturally takes the club with which he has most confidence and with which he believes he can make the shot that is wanted. It is fatal to interfere with confidence of this kind, and to substitute for it the hesitation and doubt which inevitably take possession of the man when he takes in his hands a weapon with which he rarely does well, and which, whatever you may tell him, he is convinced is utterly inadequate for the purposes of the situation. Let each man play the various strokes that have to be made in a foursome in his own way without interference, for nothing but chaos and a lost match can follow upon the enforcement upon each other of individual ideas and methods.
