This one came up when I was giving a student a lesson (strong intermediate). They went for 13/9(2), figuring they were now ahead in the race and broke contact.
I found this one pretty instructive, as it contains a few small errors/lessons that add up to a blunder (mainly, filling in the 4 gap for efficacy later and keeping the small possibility of a blot alive).
One of the reasons I don't mind giving lessons is that I often learn something too. I probably wouldn't have made the auto-pilot play, but the reinforcement of a some common motifs was nice to see.
