Learned before starting school, but my favorite checkers memory is from 1st grade.  At my elementary school, a reward for especially good behavior was to have lunch with the principal and get to play checkers with him.  I got to do this once.  He would set up in the lunchroom so everyone could see.  The set was a lovely “rug” board that looked handmade, and the checkers themselves were big weighty plastic pieces, 3 inches across.  It was a tactile pleasure.  These days I don't play checkers much, though I won't claim to have solved it, the heuristics involved don't interest me much.
