Xiangqi VS Shogi Alt

xiangqi_vs_shogi_alt1

Xiangqi vs Shogi. an extra soldier on Shogi side was added on h6 to limit cannon(similar to my another variant, but the extra soldier was on another grid). The Drop rule and The Flying general rule were both enabled. Both perpetual check and stalemate result in a loss. It is noted that some pieces' names were changed due to duplication of names. Xiangqi: K -> W(Wazir) H -> O(hOrse), P -> I(soldIer) Shogi: R -> F(Flying chariot)

TicTacRook

tictacrook_v1

"Torre en raya" in spanish. TicTacRook is a deep, abstract strategy variant for Fairy-Stockfish that seamlessly fuses chess mobility with alignment goals. Played on an empty 8x8 grid, both players start with a reservoir of 16 pieces available to drop anywhere on the board. Alternatively, players can move their existing pieces, which slide horizontally or vertically exactly like Chess Rooks, but cannot capture or jump over others. The ultimate goal is to align 5 pieces in a row—horizontally, vertically, or diagonally—to win. This hyper-mobility transforms defensive blocking, offering a dynamic, tactical challenge where a single long-range slide can instantly shatter an opponent's strategy.

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
