Not sure if this is a game tip per se but I want to mention course notes.
For the longest time, I simply played to attack the pin at all times, this is a prefectly good strategy if you can be assured of dinging it everytime, however, as alot of us miss ding against the wind, I have now made notes for each hole on each course, specifically approach shots and where is the best place to be for the easiest birdie putt (preferably uphill). Should I err long/left/right or is short better etc
I have smaller side notes as to which approaches play longer or shorter, I have taken it one step further and noted what club I have hit from specific yardages in certain winds and what the result was for future reference.
I have ranked each hole out of 10 too which enables me at a glance to know if I am capable of shooting a decent score before I even start. Knowing that at back 9 RSG, all things being equal I can shoot 26/27 is a great confidence booster before you even tee off. (I achieved a 26 earlier today) Although I must add it was my first really HOT round in quite a while.
Another important tip I can offer is regarding elevation, most folks subscribe to the theory that for every 3ft uphill = 1 yard, I find that accurate from 3i-7i, as the clubs loft increases I calculate less, 65% of elevation for 8i-Pw and only use 20% of the elevation for wedges.
eg. 15ft uphill with a 4i is 5 yards to add but only 3.25 (65%) yards with a 9i and only 1 yard (20%) with a wedge, I might add 2 yards if I expect some backspin.
Downhill I simply use 75% of the elevation for all my clubs, a little less if I have a gentle tailwind and alot less if I have a heavy tailwind.
Alot of the elevation tips mentioned above WILL vary for most club/ball combo's but with high trajectory irons, they are fairly accurate (I haven't taken into account holes that play longer/shorter, these you will mostly all already know).
Just my little contribution, it works for me and I hope it works for all of you :-)
