These are 2 imaginary wrestlers, (white is black cubes with white pieces, black is white cubes) each consisting of 16 cubes represting legs, hands, head and back
The space between wrestlers is divided into 32 cubes, 2 blocks of 16 indetical to initial wrestlers
They represent a wrestler one step closer to another wrestlers, so the total space consists of 64 cubes with intitial wrestlers
You can view it by moving all white pawns on the 4th rank and all white pieces on the 3rd rank or all black pawns on the 5th rank and all black pieces on the 6th
When you make a move on chess board, say for example you move e2 pawn to e4, the cube representing that body part and (e2 is a arm see the pic above for correspondance) will move to occupy that position in the second imaginary wrestler which was designated in the set up for the ending square. In this case the ending square is e4 which is part of the imaginary wrestler standing on the rank 3 and 4, but is invisible. e4 was designated for an arm in that wrestler. So e2 e4 will just move part of a hand representing right arm cube forward.
If you then move for example f1 bishop to e2, then the bishop will remain in the first wrestler because 1st and 2nd ranks are where the first wrestler stands but e2 field in the first wrestler was fixed for e2 pawn, so the f1 cube wich was knee will move into position where e2 arm was standing. You can sort of imagine that, you lifted up your knee to where your arm normal is.
If then bishop goes from e2 to c4, it will move one step forward because it now on the 4 rank and 3rd and 4th ranks are corresponding to second imaginary wrestler. The C4 square was fixed for c2 pawn, so the bishop will move from where it was before to stand in front of c2 pawn. C2 is left wrist, so bishop standing in front of left wrist represents abstract body position where right knee is placed in front of left wrist.
If then c4 bishop takes f7 pawn he will just be placed in a position of f7 pawn. It is interpreted as if an wrist (f7 pawn) was hooked by knee - bishop (which is unrealistic in wrestling this is why i so far prefer the arrangement where pawns are legs and not hands).
