Objective
Red cards may be counted as a positive or negitive number when counting 15s.
Rational
Adds one more way to score 15s.
Strategy
When counting the score allow a red card to be a positve or negative.
If a red card is used for a negative number it must be negative for all counts.
For example: with a crib of 8-8-7-7 and a red Ace:
- The red Ace could be scored as -1 to combine with the 8s to give 15
- The red Ace could be scored as +1 to combine with the 7s to give 15
- The red Ace could not be counted as a -1 for the 8s and a +1 for the 7s to get two counts of 15
