It's not a great game, but I was 15 at the time (which, in retrospect, was probably my peak) (Editor's Note: You are too modest, Dave - your peak was in the 1980's when you thrashed me!) and playing in my first season. It was pleasing because my opponent obvously thought he'd won my queen, but I'd seen a little further.
