All Fide rules apply, except:
- No double pawn move
- No en-passant
- No castling
- No promotion to queen
Note that the Knights can jump over the "river".
AnalysisThe "bridge" becomes a very important square.
Pawns - Must pass on the bridge to go to the other side. Gets stuck on Ld, Rd, Lw and Rw
Bishop - Can't go to the other side if the bridge is blocked. All the bishops are one the same color.
Rook - Can't go to the other side if the bridge is blocked.
King - Must pass on the bridge to go to the other side.
Knight - Jumps over the river, can always go to the other side. This makes it more powerful.
VariantsYou can add these rules to the game:
Moving bridge: Players can move the bridge sideways.
Big bridge: The bridge covers from L to R, instead of only m, so there is no river, but it is still one square. See below for a diagram.
No knight on bridge: Knights can't go on the bridge.
Bishop palace: Bishops change place with rooks. They are stuck on their side. (Except if used with the changing color bishop move rule.)
King palace: The kings can't cross the bridge.
Tiny king palace: The kings can cross the bridge. They can't go to the L or R column or to the d or w rows(they are stuck in 3x3 palaces, as in Xiangqi).
Side pawn move: Pawns can move sideways on Ld, Rd, Lw and Rw, so they don't get stuck.
Changing color bishop move: Bishops on k can move to md or mw. Bishops on md or mw can move to k(the bridge).
Queen: Replace a piece by a queen.
Square Head Glinsky: Pawns take sideways.
Stalemate A: On stalemate, instead of a draw, the stalemated king wins. (when you get stalemated, you're happy aren't you? :) )
Stalemate B: On stalemate, instead of a draw, the stalemated king loses.
Perpetual check: If you can perpetual check the other player, you win.
All your base are belong to us: Replace bishops with crooked bishops. Replace knights with camels. Replace rooks by murray lions. See the piececlopedia.
Dopefish: Replace the knights with dopefish: they move like queens, but can't do non-taking moves. (they must take every move)
