Thanks Horus for posting this. I should point out this is the "original" bulldog chess but is not played very often. But I definitely would like to play it again!
Since no piece is very strong (the guards are about 3 points - same as king), the games often are focused on tactical pawn formations. The rooks can come out anytime (due to the transparent bulldogs) but it's not clear if that is good strategy. Doing so can be a fault similar to playing the queen too early in classical chess.
Anyway chess is already complicated enough. This game just makes it slightly more complicated by the larger board, the guards, and some "weak" bulldogs.
Would like to see it played more often.
Game rules:
Board: 10 x 8 (see image below).
The pieces:
Bulldog (D) - Moves and attacks the same as a pawn, except pieces FROM ITS OWN ARMY ONLY can pass over it in any direction. If a bull dog reaches the 8th rank it can immediately move to any square in the first four ranks (but cannot capture a piece during this move). This move can only be completed during the same move it reaches the 8th rank. (If this option is not taken, the right to do so later is forfeited). The bulldog does not promote to other pieces as pawns do.
Guard (G) - Moves and captures like a non-royal king (ie: it can move into an attack).
Board Setup:
Castling:
The rules of castling are similar as in classical chess, however, with the board 10 squares wide, the king travels three squares rather than two. The rook finishes adjacent to the king. All squares between the king and the involved rook must be unoccupied.
Misc: Pawns play the same as in classical chess. Pawns can promote to queen, rook, bishop, knight in addition to guard. Promotions are unlimited (not restricted to pieces that have been captured).
Other rules of this game are identical with rules of classical chess.
