Ralph Betza's + a(href="https://www.chessvariants.com/unequal.dir/cwda.html") + | Chess with Different Armies + | was an inspiration, but the goal was to be a little more streamlined + | with the theme here. + | In this case, the theme of the new army is knight-based movement, + | where most pieces have an element of knight movement. + | Given the knight (or horse) theme, this was modeled after the + | Mongol army and named the Horde. An "orda" was a military structure + | for the people of the Steppes, which also gave rise to the English word + | "horde." The original chess army is named the Kingdom for contrast. + | The game itself is incredibly balanced by engine evaluation (even more + | than standard chess), with a near 50-50 win ratio for + | the Kingdom and Horde. + +h3 General Rules + +ol + li. + Setup is as above. Despite new pieces, the placement of the Horde pieces + mirror their chess counterparts. + li The Kingdom always moves first. + li The Horde cannot castle. + li. + As Horde pawns start on the third rank, they do not have the option to + move two spaces or be captured by en passant. Kingdom pawns retain the + ability to move two spaces initially and to be captured via en passant. + li Pawns can only promote to a queen or kheshig. + li. + An additional method of victory is available: called campmate. Campmate is + achieved by moving one's king into the final rank without being check. + li Other rules, including stalemate and repetition are as in chess. + +h3 Horde Pieces + +p. + There are four new units unique* to the Horde: 2 Lancers, 2 Horse Archers, + 2 Kheshigs, and 1 Yurt (* exception being that the Kingdom can still obtain + a Kheshig by promotion). The Kheshigs are the strongest piece + (knight + king movement) and lead each flank, while the Yurt is a fairly + weak piece unlike the Queen. The Horde's king is called the Khan and looks + different, but is essentially the same as the Kingdom's King, also using + the same abbreviation (K) — the change is purely aesthetic and + thematic. + +p. + The Horde Lancer and Horse Archer are unique in that they capture + differently than movement. Remember that the Horde is horse-based, so the + Lancer and Horse Archer both move like knights. They capture like rooks + and bishops, respectively. The Kheshig is more traditional in that it + captures where it moves; it combines the movements of the knight and king. + Similarly, the Yurt also captures the same way it moves; it moves as the + silver general in Shogi. + +table + tr + th Horde piece + th Kingdom "counterpart" + th Movement + th Capture + tr + td Yurt + td Queen + td "Silver" + td "Silver" + tr + td Horse Archer + td Bishop + td Knight + td Bishop + tr + td Kheshig + td Knight + td Knight+King + td Knight+King + tr + td Lancer + td Rook + td Knight + td Rook + +p. + Details and diagrams of each piece are below. Green dots represent movement, + red dots represent capture, and yellow represents both. + +h4 Yurt (Y) + +img.img-center(src="/images/variants/Orda/Yurt.png") + +p. + The Yurt moves and captures one space diagonally or one space forward. + This is the same as a silver general from Shogi or the bishop/khon + from Makruk. There is only one yurt, starting in the queen's spot, + but unlike the queen, it is very much a minor piece, the weakest piece + in the game aside from a pawn. It should not be underestimated though, + because it is one of the few Horde pieces that can move and capture + the same way. The other two are the Khan and Kheshig, which are the two + most valuable pieces. Therefore the yurt has the unique role of reliably + supporting pawns and other pieces without fear of retaliation. + +p. + A yurt is a mobile home for Mongol and Turkic people in the steppes of + Asia. Their limited mobility but importance for supporting the army is + reflected in this piece. + +h4 Kheshig (H) + +img.img-center(src="/images/variants/Orda/Kheshig.png") + +p. + The Kheshig is a hybrid piece that moves and captures as a knight and + king combined. This piece type is also generically called the centaur. + The kheshig starts in the knight's spot, but unlike the knight, + is the strongest Horde piece. It can be thought of the general that leads + its own troop on each flank. It is generally preferred to keep the kheshigs + safely behind during early to mid game because of their extreme importance + to the Horde in the endgame. + +p. + The kheshigs were the elite imperial guard for the Mongol royalty. + Appropriately, it is incredibly difficult for the Kingdom to checkmate + the khan without at least eliminating one of his kheshigs first. + +h4 Horse Archer (A) + +img.img-center(src="/images/variants/Orda/Archer.png") + +p. + The Horse Archer, or simply abbreviated Archer, is a unique "pseudohybrid" + piece that moves and attacks differently. The archer moves as a knight but + captures as a bishop. Because the archer is not colorbound, + its value is greater than its bishop counterpart. + +p. + Horse Archers were one of the two core components of the Mongol cavalry, + functioning as the light cavalry. Their speed and prowess as mounted + archers made them a unique threat. Their ability to quickly position + themselves for a deadly skewer or fork make them a dangerous threat + for the Kingdom. + +h4 Lancer (L) + +img.img-center(src="/images/variants/Orda/Lancer.png") + +p. + The Lancer is a unique "pseudohybrid" piece that moves and attacks + differently. The lancer moves as a knight but captures as a rook. + Because the lancer is not as mobile as the rook, it is generally + weaker than the rook, and this becomes more pronounced in the endgame, + as it cannot move across the board as quickly as a rook can. + Its value is still comparable to the horse archer. + +p. + Lancers were one of the two core components of the Mongol cavalry, + functioning as the heavy cavalry. Despite being weaker than the rook, + their ability to come into play much earlier in the game is an advantage + that the Horde player should utilize. + +h4 Piece valuation + +p. + Accurate piece values are unknown.

Este tipo de pieza también se llama centauro, + genéricamente. El kheshig comienza en la ubicación del jinete, pero a + diferencia de esto la última es la pieza más poderosa de la Horda. + Puedes imaginar como un general que lideraría sus propias tropas en cada + flanco. En general, es preferible mantener a los kheshigs en el refugio + detrás de la apertura hasta la mitad del juego, debido a su extrema + importancia para la Horda en la final. + +p. + Los kheshigs eran la guardia imperial de élite en el reino mongol. + Entonces es apropiado que sea increíblemente difícil para el Reino + matar un khan sin eliminar al menos uno de los kheshigs. + +h4 Arquero a caballo (A) + +img.img-center(src="/images/variantes/Orda/Archer.png") + +p. + El arquero (a caballo) es una pieza única "pseudo-híbrida" que se mueve + y capturar de manera diferente.

Se mueve como un caballo pero captura como una torre. + El lancero no es tan móvil como la torre, generalmente es más débil + que este último, especialmente en la final porque no puede cruzar + el tablero muy rápido.
