# 1. Generate an index that maps 2-templates (like "_l___x") to words ("climax").
# 2. Find 2-templates that map to just one word.

# The Rules of Mindy Coat
# =======================
# => Four players, opposite sides are in teams.
# => Deal 5 cards each, one-by-one starting left of the dealer.
# => Left of the dealer calls trump looking at those 5.
# => Dealer deals the last 8 cards out (starts on the left).
# => Highest card of the trick wins, unless a trump is thrown, in which case the highest trump wins.
# => Team that takes the most tens wins, unless each takes two, in which case the total number of tricks is counted.
# => (Must follow suit unless you don't have it.)
