So you are suggesting a dictionary where the key pairs are the win-lose
pairs (i.e. 'scissors' broken by 'rock', etc). Sean also suggested a
dictionary approach, and again I must say that it does give a really
nice neat look to the code, and is easy to read too. Thank you for your
suggestion; I am certainly more inclined to try to use that approach.
All the best
