I believe that some, if not most, of these respected writers read this column. For whatever reason, they have chosen not to respond. Check out my post entitled, "Responding to CMC."
Are -8/-8 and -9/-9 normal match scores? Check out the rollout results posted below, where the same simple race is a pass at -8/-8 but a take at -9/-9.
Cube action and checker play in matches are a lot more complicated than the NMS folks would have us believe.
