This is as barebones as I can get it in order to explain my problem.

************************************************** **************************
A PokerTable 'is' a CardTable and a PokerPlayer 'is' a CardPlayer.
A CardTable 'has' CardPlayers and a PokerTable 'has' PokerPlayers.
The only annoying thing is that every time I want to refer to the
player[i].chips member within PokerTable, I have to explicitly cast
player[i] to a PokerPlayer first in order to get at it.
What I want is for player[i] to 'be' a PokerPlayer within the PokerTable
class without having to cast it every time. I wouldn't mind so much if
CardPlayer[] player could be cast to PokerPlayer[] but I can't get that to
work.
Any ideas how to implement this idea?
