Slide-chessSlide-chess is an entry by Joao Pedro Neto for the 44-squares contest.
setup: ,() are cages that slide around the board (check rules)  -> White cage () -> Black cage (notice they begin at the player's last row) 8 [ ] 7 r n b k b n r 6 p p p p p p p 5 . . . . . . . 4 . . . . . . . 3 O O O O O O O 2 R N B K B N R 1 ( ) a b c d e f g h i(so 6*7+2 = 44 squares)
- FIDE rules, except:
- On each move, each player must do one of:
- make a regular Chess move, which includes moving or capturing into or out of either cage.
- move his cage (with any contents) to any empty edge or corner (orthogonally or diagonally) adjacent to a square board; b1: It is illegal to check the enemy King with a cage move b2: A player may not move his cage twice consecutively.
- insert his cage (with any contents) orthogonally into the board, shifting the other cells in line until a cage appears at the opposite edge (which must have been empty).
Eg: [ ] r . b k b n r p p p p . p p . . O . p . .(n) . . . . . . . O O . O O O O R N B K B N R becomes: [ ] r . b k b n r p p p p . p p ( ). O . p . . n . . . . . . . O O . O O O O R N B K B N R
- No double initial pawn step; no castling.
- When a pawn reaches the 2nd/7th rank, the mover decides how it promotes (the pawn may promote to a Queen).
- No king must ever be in a cage.
