Definitions:

Grasshopper(G): Moves along Q-lines over another unit of either color to the square immediately beyond that unit. A capture may be made on arrival, but the hurdle is not affected.

Rookhopper: As Grasshopper, but moves on Rook lines only.

Bishophopper: As Grasshopper, but moves on Bishop lines only.

Zebra – (2,3) Leaper

Locust (L): moves on Q-lines but only by capturing an enemy unit, arriving on the square immediately beyond that unit, which must be vacant.

Rook-Locust (LR): Moves like Locust, but on Rook-lines only.

Bishop-Locust (LB): Moves like Locust, but on Bishop-lines only.

Nightrider(N): A Rider along a straight line on squares lying a Knight`s move away from each other.

Kangaroo (KA): Moves along Queen-lines like a Grasshopper, but over 2 hurdles (which may or may not stand on adjacent squares) to the square immediately beyond the second hurdle. A capture may be made on arrival, but the hurdles are not affected.

Anti-Andernach:A piece (excluding King) changes its color after any non-capturing move. After capture, the piece retains its color. Rooks on a1, h1, a8 and h8 can be used for castling, provided the usual other rules for that move are satisfied. After castling, Rooks do not change color, If White makes a non-capturing move with neutral or halfneutral piece, that piece becomes black and vice versa.

PWC: When a capture is made, the captured unit (except a King) is replaced on the square the capturing unit just leaves. A Pawn is immovable on its 1st rank.

N.230. This composer has done many beautiful problems using the Hybrid. Once you understand what happens here you admire the simple but intriguing concept of selfblock moves becoming guarding moves ! Great !

No.230
I’ve seen only few fairy direct mates and to me, such change of effects on the same squares arranged in a cycle looks incredible. Flaws in aesthetic and economy, caused by a construction of the keys, still do not spoil the purity of the idea.

Could the flaws in economy and aestethic be justified in a sixfold cycle?
