This is a variation on J.P. Neto's Abstract Chess. It uses power units, hereafter called Ponies.
In the square versions hereafter presented, two Ponies make a Knight, three make a Bishop, and four, a Rook.
There are no Queens. 

In the basic version, the three pieces above can split up, leaving one Poney behind, and becoming 
the immediately lesser piece on the landed-on cell. If this cell was occupied by a friendly piece, 
the two merge together -if possible, to form a new, more potent one .

In the advanced version, pieces are free to split up and merge down in any legal way.
To keep thing simple, splits and captures are mutually exclusive.
To split a piece up, click on its destination cell.
Apart from that, Knights, Bishops and Rooks behave in the usual, orthodox Chess way.

A Poney also moves and captures in the classical fashion of a Chess Pawn, but it does not promote 
(as it is busy doing just that during the game, anyway), nor does it perform an initial double-step 
or capture en-passant.

The King does not castle (less hassle), and loses the game if mated.

On occasions, a Poney will maddeningly refuse to merge with a piece.
ZoG is weak at this, and even weaker in more elaborate, hexagonal-lattice-board versions 
(with counters and stuff, nothing much to brag about).
