I've found another mixed-dimensions/chess-on-2-boards game. It is Sub-Chess, designed by Alexander Chebotaryov, 1988, and found on page 196 in the Classified Enc, of Chess Variants. There are 2 versions of the game, Chess-112 and Chess-M-48, using the same board but some different movement and capture rules. Pieces are FIDE standard.

The basic idea is to use a standard chess set, and divide the central 16 squares into 4 smaller squares each, creating a smaller [S] 8x8 board incorporated in the middle of the larger [L] 8x8 board. Pieces in the center squares would simultaneously be on an L square and an S square. Therefore, pieces might move either on the L or S squares in the center of the board. 

This would allow a knight, moving normally on the small squares, to make a 1 square diagonal or orthogonal move on the large board, for example. And it would require 2 blocking pieces next to each other in the center large squares. 

Is anyone familiar with this game who might comment on how it plays? These sorts of games are tricky to get right.
