PIcking half to play one game and half to play the other is not an
option.  For one, there really isn't a concept of half when a variable
number of players are available on a given Saturday.  For two, we
could have an unexpected absence, or during the game an injury.  For
three, the parents paid to have their child play in the league, and
the league runs until the end of October, not long enough for that
strategy to work out.
