No.604 – Peter Harris – Трехфигурная задача в типичном стиле Питера! (JV)

Определения:

Patrol Chess: A piece can capture or give check only if it is observed by a piece of its own side.

Sentinels Pion Neutre: When a piece (Pawn excluded) leaves a square outside the first and last rows, it leaves a nP unless 8 neutral Pawns are already on the board. (Popeye’s interpretation)

In the (II) 1.Ng7 solution: Black cannot avoid mating by returning the B to g8 because it will be empowered by the Ph7. This explains why the promotion has to be to a B and not to a Q. A Q could move to f7 and not be empowered. (Author)
