No.125 – #2 by Jean-Marc LOUSTAU –  A difficult fairy-twomover.  (JV)

Definitions:

LEO(LE): Moves as Queen, but captures only by hopping over a hurdle to any square beyond.

PAO(PA): Moves as Rook, but captures only by hopping over a hurdle to any square beyond.

VAO(VA): Moves as Bishop, but captures only by hopping over a hurdle to any square beyond.

NAO(NA): Moves as Leo, but on Nightrider-lines instead of Queen-lines.

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

Equihopper and Non-Stop Equihopper(NE): Moves along any line over another unit of either colour to a square situated such that the hurdle stands at the mid-point between the Equihopper’s departure and arrival squares. The English (standard) Equihopper cannot pass over an obstruction other than the hurdle when playing along Queen-lines. The non-stop/French Equihopper does not have this restriction.

### One Response to Original Problems (66)

Another amazing problem from Jean-Marc. Remarkable concept to show Lacney theme! Anyone looking deep enough will find that everything depends on the guard/unguard of the squares d6, d7, d8. To conceive and realise this concept shows high imagination and construction skill. Well done again Mr.Loutau !!
