This game was created in the former Soviet Union. Needs 47 yellow disks for one side and 47 blue disks for the other. The traditional chess pieces are built up from these disks. A king needs 8, queen 7, bishop 5, knight 4, rook 3, pawn 1. If you move part of the disks from a piece, you change the piece to two weaker ones, or you can move disks onto a piece of your own and create one stronger piece. Pawns can only do this with their capturing move. There can be more than one of any pieces including king. A player can never be without a king. A king can be captured just like other pieces in normal chess as long as the player who just lost his last king can form a new one in his next move. - BoardGameGeek
