The Gladiatrix moves by colliding, diagonally or orthogonally, against any piece, and then deviating to any of the two adjacent orthogonals or diagonals (in the prolonged movement direction). It captures on the second leg only. The Gladiatrix can also move by colliding against the margin, whereby only one movement direction is available after collision. Without screens to collide against the Gladiatrix cannot move. The Gladiatrix's value is 6, which corresponds to rook + pawn (preliminary estimate). Other rules are the same as in standard chess, except for the possible promotion to Gladiatrix. The Gladiatrix is the most powerful of the bifurcation pieces. It is, arguably, the most agile among all the known pieces. It has the capacity of zigzaging between the pieces and find its way in quite congested situations. As it moves by coordinating with other pieces, the Gladiatrix is a highly cooperative piece. The structure on the board decides its possibilities. Although screens for colliding become fewer, the Gladiatrix does not loose power in the endgame. But, unlike the rook, the Gladiatrix cannot, together with the king, give mate to the enemy king. The unusual H-board makes it possible to introduce the Gladiatrix while allowing it a proper amount of movement freedom in the opening. Note that, on the knight-files, the Gladiatrix can also collide orthogonally with the margin and continue to the extra corner square.

Gladiatrix Chess can also be played with Kwaggas instead of knights. The Kwagga moves like an extended knight, three squares orthogonally plus one step to the side. It can multiply this jump in the same direction. This means that the Kwagga moves like a Camelrider. However, unlike the Camelrider, the Kwagga can only capture on the first jump, and the next square must be empty. The Kwagga is as valuable as a bishop (my estimate). The Kwagga was originally invented for my Bodyguard Chess.
