Full Belt Chess is a chess variant, invented by Michael Howe of Middletown, Connecticut, USA. This game probably was invented in the 1990's. The information here is from Variant Chess, issue 23, spring 1997, where Peter Wood describes the game, based on a description in Eteroscacco. Peter Wood's text is titled: Not for the Faint-Hearted, which describes the complexity of the variant quite well; games can easily end quite quickly with a mate!
The rules of orthodox chess are followed, but with the following changes.
After making a move, that is legal under the normal rules of chess,
the player must made a belt move. A belt move means that the player
takes one row or column (belt) and moves this belt any number of squares
in one direction, where the edges of the belt are considered to be connected.
For instance, white could start with 1. Ng1-f3, and then rotate the f-column
four squares; thus, the knight ends up on f7; whites pawn from f2 goes
to f6, and blacks bishop on f8 goes to f4:
King h1; Queen d1; Rook a1,h1; Knight b1, f7; Bishop c1, f5; Pawn a2, b2, c2, d2, e2, f6, g2, h2.
King e8; Queen d8; Rook a8, h8; Knight b8, g8; Bishop c8, f4; Pawn a7, b7, c7, d7, e7, f3, g7, h7.
There are two optional rules:
King h1; Queen g1; Rook f1, e1; Knight d1, c1; Bishop b1, a1; Pawn a2, b2, c2, d2, e2, f2, g2, h2.
King a8; Queen b8; Rook c8, d8; Knight e8, f8; Bishop g8, h8; Pawn a7, b7, c7, d7, e7, f7, g7, h7.
