Ain't it the truth, at least from the single digit handicap perspective.
About 80% of the time I play with guys from GCA, I turn into a hacker, despite no pressure and fine playing companions.
Similar things usually happen in tournaments, as well, with pressure and not always fine playing companions.
I feel the reasons I don't usually play well with other guys are:
1) too relaxed, with mind not concentrating on game
2) unfamiliarity with course, such as when not to hit driver, where not to hit it, etc.
3) first time playing course means "go for it" and "never lay up" on all gambling type holes, reachable par 5's with trouble lurking, etc.
4) different playing conditions such as faster and tougher greens and less forgiving areas when shots are a little off the mark.
5) I'm not as good as I think I am
Here's my range of scores when playing with other GCAers:
75-somewhere in the 90's
, handicap usually 5-7.
I wish I cared less about score.
But it's not about score, right?
