Praetorian chess

praetorian

Praetorian Chess is a “different armies” variant in which classical White (RNBQKBNR) faces the Praetorian army VWXIKXWV (this setup has an empirical White score of 50.365%). The rules are otherwise those of standard chess, except that there is no castling. Check, checkmate, en passant, and ordinary pawn movement are unchanged. Pawns promote to Queen, Rook, Bishop, or Knight. Praetorian pieces: - V Arbalest (Roobis, mRcB): moves like a Rook, but captures like a Bishop. - W Sentinel (Rooman, mRcK): moves like a Rook, but captures one square in any direction. - X Praetorian (Bers, KR): combines Rook and King movement. - I Ballista (Bisroo, mBcR): moves like a Bishop, but captures like a Rook. - K Caesar: the ordinary royal King. Empirical piece values computed in this matchup: Praetorian X (Bers) = 5.98 Ballista I (Bisroo) = 3.87 Arbalest V (Roobis) = 3.64 Sentinel W (Rooman) = 3.28 Queen Q = 8.50 Rook R = 4.26 Bishop B = 3.28 Knight N = 2.97 Pawn P = 1.00

Connect 4 but you align chess pieces. Checkmate/capturing the king is not a win. Black pawns do move down

Different Armies HWAGKAWH

differentarmies_v3

Classical White (RNBQKBNR) plays against the empirically balanced Black army HWAGKAWH (reported White score: 50.67%). Black's pieces are: H = Biskni, moves like a Bishop but captures/checks like a Knight (value = 2.49 pawn); W = Rooman, moves like a Rook but captures like a non-royal King (value = 3.28 pawn); A = Archbishop, combines Bishop and Knight movement (value = 6.79); G = Manroo, moves like a non-royal King but captures/checks like a Rook (value = 3.74). Otherwise the rules are those of chess, except there is no castling; pawns promote to Queen (value = 8.50), Rook (value = 4.26), Bishop (value = 3.28), or Knight (value = 2.97).

New Shogi. The 'Keima (桂馬)' has been removed, and the 'Copper General (銅将)', 'Drunken Elephant (酔象)', and 'Knight (騎士)' have been added. With the exception of the King, all pieces can move like the King upon promotion, in addition to their existing movement. Pawn drop checkmates are also possible, and there are no draws.
