No.814 (PH)

No.814 by Peter Harris – Author writes that the problem was made to encourage composers to use the Maxi Ultra condition. An interesting role of the wR! (JV)

Definitions:

White Maximummer Ultra: White’s only legal move is his longest – calculated per maxi rules.

White Maximummer: White must play the geometrically longest move or may choose from among longest moves of equal length, distances being measured from the center of each square. Diagonal and oblique distances are measured from the orthogonal coordinates by using Pythagora’s theorem (take the square root of the sum of the squares of the orthogonal distances). All other orthodox chess rules apply.

Sentinels Pion Advers: When a piece (not a Pawn) moves, a Pawn of the colour of the opposite side appears on the vacated square if it is not on the first or the last rank, and if there are less than 8 Pawns of that colour on the board.
