Replying again on this one.

You made the breakthrough for me. But I was thinking
in terms of true/false, and I also implemented the
cards a little differently. 

The concept of a round as an object wasn't compelling
enough to me personally. This is how I ended up 
doing it.


class Card
  # (snip)
  def beats(other)
    if @suit == other.suit
      Ranks.index(@rank) > Ranks.index(other.rank)
    elsif @suit == "S"
      true
    else
      false
    end
  end

end


class Driver
  # (snip)
  def Driver.winner(cards)
    high = cards[0]
    cards[1..3].each {|card| high=card if card.beats(high) }
    high
  end
end  


Ciao,
Hal
