The Book of I Ching lays out the 64 Hexagrams, which we might consider as analogous to the Chess Board's 64 squares, in structural depth and complexity without limit. And Bobby Fischer died at 64: they say he ran out of squares - or was that hexagrams? I played OTB, mostly at the Saint Paul (Minnesota) Castle Chess Club, a strong club, in the late 80s early 90s. Dropped out of chess for a couple of decades, and now I'm back, as a 64 year old coffee house style wood pusher.
