Antoine: Yes, a good Achernar game may last, in expected number of moves,
around 80-100, but it is not the case with Deneb. Average number of moves
in a Deneb game should be around 40-50. Chess on a Larger Board With No So
Few Pieces dropped avarage should be around 80-100 moves, but I think it is
not more than this, and for Chess with Terrain, my initial estimation of
around 100 moves may be short, now I´m thinking it is over 150. dimensions
and terrain are determinant in this case. The number of average number of
moves to finish is a characteristic, but not necessarily a quality factor.
If it is good or bad depends on preferences.
