Here's another perfectly-good '9x9', technically, to add now we did not throw into our major list on 9x9. Technically, because of 73 squares to accomodate better the Berolina-related Pawns. See first comment for 9x9 Missoum's Rotating Chess where this DD Pawn actually eventuates earlier. Aiken's best other one is Eight-Stone, 8x9 and 72 squares. These Pawns may beat Berolina for half of all possible arrays, depending how we think about it. Brainking has similar game and Pawns under different name Legan from 1913, likely point of origin.
