The Seirawan Chess Upgrade Kit includes only the Elephant and Hawk Chess Pieces (as shown above) and is designed to complement the Olympian Black and Natural Premium Chess Set (item #1157).

Seirawan Chess is a revolutionary new Chess variation that has one single purpose - to make Chess fun again! In an age where your average desktop computer is capable of defeating the world's strongest Chess players, Seirawan Chess builds upon the classical foundation of Chess but adds two new pieces - The Elephant and the Hawk. The addition of these two new pieces changes everything and results in a fun, exciting game that is equally challenging for beginners as it is for grandmasters.

The Hawk can move like a knight or bishop. The Elephant can move like a knight or rook. They are not in play at the start of the game, which begins exactly as a normal chess game. When a player first moves a piece from its original square, that player has the option of placing the Hawk or Elephant on the vacated square, as part of the player's move. Thus, if a player played Ng1-f3, he or she could place the Hawk or Elephant on g1. The move would be recorded as 1.Nf3(Hg1).

Since each side has eight pieces, a player has eight opportunities to bring the Hawk and Elephant into play. If a player fails to do so, the unplaced piece remains out of play. When a player castles, the Hawk or Elephant may be placed on either e1(8) or h1(8)/a1(8), but not on both. Two moves are required to bring both the Hawk and Elephant into play. A player may promote a pawn to either a Hawk or an Elephant.
