The 3 commenters are not mentioning yet 96 squares and 100 squares in pre-modern chesses. John Ayer's revised genealogical timeline changes Courierspiel(96) as contributing to Modern Chess of 64 squares, rather than traditional thought of its being dead-end branch. Is that only for the Bishop? Then more importantly and maybe radically, Ayer's article posits I think something like 8 -> 10 -> 8 in the very early going, with Shatranj al-Kamil v.1 being the large size 100 10x10.
