I am making a bot that plays opening moves from a PGN. When the player reaches a position out of PGN, I want to give a score to the player how well he followed the PGN. What kind of statistics can I give the player for entertainment.
I am thinking:
ply The ply number that is reached.
plies to next branch Number of plies to next branch.
branches Number of branches that has been taken.
Would this be accurate, and what can I add to them?
