About a month ago I played with two friends from high school and another who was a Jr. on that high school team. One was the state champ in HS 2 years in a row and is a +4. The other is a +3 or 2 I believe. The Jr is like a 3 or 4 handicap at best but drives the ball 300 yards like the other two did. I only drive like 250-260 so that alone was intimidating. I was pretty nervous but knew they were good guys so I figured it didn't matter how I played. We played doubles match with me and the +4 vs the other two. Best single score of the teams won the hole.
To my surprise, I hit a good drive and an approach to 30 ft and sank the long birdie. Won one of two holes for us for the day. I Birdied the 11th as well with a 12ft birdie. It's intimidating that my partner hit his drive 320 about 15y left of the green. Yet he still only made par while I made birdie. So you can definitely hang with them, you just have to avoid the penalties, the bunkers, the rough, and make sure you really focus on your short game.
My partner shot 66. The other two shot 70 and 73 I believe. I shot 81. Not so great but I can live with it. I played like 4 or 5 points above my handicap which is not too bad, considering I had two OBs. Ugh. So embarrasing, those guys didn't have a single penalty.
Anyways, just play within yourself and don't go for the green if the hazard is at 200 and its at 220. Layup. They will go for it but maybe you won't. The risks are too great for your skill, perhaps. It's all about how you feel and your confidence. But if you don't want to embarrass yourself, don't be afraid to play safe.
Learn what you can be most importantly have a good attitude and a good time.
