Define an 'Event', generally applicable, as either a Capture or a
Check. An interesting game, one likely to have a high baseline for all
four Depth-Drama-Decisiveness-Clarity, should have event frequency 33-50%
per paired move. In other words, by move 30 say, there should ordinarily
be 10 or 15 captures or checks, either way B-W and W-B.
