Don't try experimental shots on a new system when your opponent is dormy. It may be quite true that those you make on the old system are very bad, but you had better stick to them until the end of this match at any rate.
Do not attempt to play two kinds of golf at the same time; that is to say, if you are playing for a medal, do not keep up a hole-to-hole match with your partner. You will become confused, with no clear idea of what you are trying to do, and you will probably win neither the medal nor the match. If you feel that you must match yourself in some manner with the man who is going round with you, back your net return against his.
Because you do a hole in bogey, or even sometimes in one stroke less, do not always take it for granted that you have therefore played perfect golf. Some bogeys are very easy, and some shots are very fluky. A man may miss his drive, run a bunker, and hole out with his mashie, beating bogey by a stroke. But he would be well advised not to say anything about it afterwards, lest he should be asked for details. Not the smallest credit attaches to him for this remarkable performance.
Always play from a low tee, except when the wind is behind you.
See that your head remains rigid, from the moment when you have finally taken up your position and are ready for your swing, until you have struck the ball.
