4 Good tip for Playing hard Golf Courses

1. Take your practice swing to the depth of the ball
When you have a shot from the rough, don't just take a mindless practice swing hack. Find a similar area of grass, and practice your swing at the same depth your ball sits. Then, if the club grabs or slides through easily, you can calibrate for that on the real shot.
2. Play your bunker shots to the same tier as the flag
On every bunker shot, look to see where the most dangerous place to end up is. For example, if you were playing to a flag on an upper tier and you had to angle a shot up to that tier, leaving it short could send the ball rolling back off the front of the green into a collection area. Aim for the fattest part of the tier where the flag is, even if you're not aiming at the hole.
3. Loft your greenside shots instead of bump-and-running them
On really fast greens with holes cut close to the edges, you can't get away with hitting "safe" running chips. You need to use your L-wedge to hit pitches with some spin so they check up and trickle to the hole. Keep your weight left and your nose over the ball, and practice making crisp contact with the ball first, then the grass. Gouging a giant divot doesn't produce backspin.
4. Translate the green speed before every putt you take
When greens run 13 or 14 on the Stimpmeter, it's easy to blow a 12-footer 10 feet by the hole. On the practice green, place another ball halfway to the cup, just outside your line, and pretend the hole is even with the second ball. This will help you calibrate your speed. Then, on the course, visualize that ball on every putt.
