The Echidna moves like a king, one step in any direction, but it cannot capture directly. Instead the Echidna has the power to repulse any piece (friend or foe, including pawns) that is being approached, provided that any intervening squares are empty. The piece is repulsed to the square immediately beyond the next piece, thus causing the startled piece to jump beyond a screen in sheer fright. An enemy piece positioned here would be captured. If there is no screen, or the square behind the screen is occupied by a friendly piece, then no repulsion occurs. In case of an enemy pawn, it cannot be pushed back to the first rank, that is, the second rank is the limit. The enemy pawn can be pushed to its promotion square, whereby it is promoted to a queen, as only option. A friendly pawn, pushed to the last rank, can promote as usual. Other rules are the same as in standard chess, except for the possible promotion to Echidna. The Echidna's value is 3, that is, the same as a bishop or knight (preliminary estimate). Despite its low value the Echidna has capacities that borders on the magical.
Echidna 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). |
