Examples
Basic word suggestion
# Find suggestions for blue player. Suggestions are sorted by possible
# territory gain, and secondarily by enemy player territory loss, and
# the top ten (typically of thousands) are shown. May not lead to best
# strategy. Words are not unique, ie there is more than one way to
# spell 'courier'
$ ./game.py example/example.png blue
word: airier, territory gain 5, enemy territory loss 5
word: courier, territory gain 5, enemy territory loss 5
word: rainier, territory gain 5, enemy territory loss 5
word: courier, territory gain 5, enemy territory loss 4
word: carrie, territory gain 4, enemy territory loss 5
word: aerie, territory gain 4, enemy territory loss 5
word: racine, territory gain 4, enemy territory loss 5
word: anorexic, territory gain 4, enemy territory loss 5
word: erica, territory gain 4, enemy territory loss 5
Vulnerable enemy capital
# Taking the enemy capital grants an extra turn, and it is usually possible
# to win on the extra turn. If the enemy capital is vulnerable, the code
# suggests the word which takes the capital along with the maximum number
# of other enemy tiles
$ ./game.py example/ss.png red
Possible to gain extra turn: suggestions.png
Extra turn / finishing move
# This is the result of making the above suggested move. It is trivially
# easy to finish off blue using the extra turn. My code recognizes that
# the game is winnable and suggests the longest and shortest winning moves
$ ./game.py example/ss2.png red
Game is winnable this turn: suggestions.png
