Here are my few but precious tips on how to score low:
1. Whatever you do, hit the fairway. If you are in the fairway, it is easier to stop the ball than from the rough, not to mention that rough lies are a range, not an exact percentage. The ball comes out differently every time.
2. On any shot of reasonable control (for me and most others that is 125 and in), try to leave yourself an uphill putt. The worst thing ever for my game was not realizing this sooner... Those sidehill putts in tournaments-especially on Oakmont- killed my momentum. Even uphill/sidehill putts are ok, because they do not break as much.
3. Make good friends with a good bunch of WGTers. Not only is multiplayer fun, but it generates a ton of xp, especially with alternate shot. Your friend won't tend to quit games on you as much, so you are more likely to finish your full round with them than others.
4. Have a go-to shot around the greens. Training myself to hit a full backspin pitch (my go-to) shot whenever I can has helped me hit my short shots closer, and making par putts shorter.
5. Learn to plan out your hole before you tee off. Rid your game of those awkward angles into greens and take out the risk while still being agressive. Take the 4th hole at kiawah for example. With that front pin, most people are stymied. If you drive down the left, it improves your angle to the green and allows you to go at the pin. The natural play is half way between the bunkers and rough line. That is actually the toughest angle. You either want to challenge the rough and take the greenside bunkers out of play, or challenge the fairway bunkers and face the greenside bunkers head on. Planning could prevent that awkward angle
