Ok so I got this by playing against an active rival, as I haven’t got any friends who have this game.
First off, I would recommend selecting a popular course, say Little Brook Manor. Select new round and on the left hand side select “add player”.
Now choose “Add Rival” and it will list recent players. Just add them and then play a round with them as your rival. The achievement will unlock when you complete the round.
If there are no rivals on that course, just select another, and keep going until you find someone. Unfortunately, the community has moved on to TGC2019, so this achievement will get harder as time passes.
Good luck!!
