Read "A Round of Gold With Tommy Armour"
A little disappointed. I was hoping for some major new insights into course management, and in this regard it was sadly lacking. Most of his advice on course management relates to playing conservatively, thinking of a hole's architecture and playing to the right place on the fairway, being confident over water carries etc etc - i.e. nothing that revelatory. Its also hard to work out club selections etc being discussed for the simple reason that it was written in 1959 - they are taking 4 wood where we would take 4 iron today.
Also some of his instruction - e.g. regarding foot work - is out of date
But there are some nuggets hidden here I think e.g.
1 - no borrow on 2 foot putts
2 - aim to miss a putt on the high side
3 - I like his idea of swinging rhythmically but smacking the ball away with the hands
4 - its sometimes worth laying up in light rough rather than fairway if it opens the green up
5 - good advice on grip and grip strength
So worth the read and probably worth a second read - read it in 1 evening anyway.
