No.635 Paul Rãican – Богатая игра при наличии всего двух нейтральных фигур на доске! (JV)

Определения:

Sentinels Pion neutre: When a piece (Pawn excluded) leaves a square outside the first and last rows, a white piece leaves a wP, a black piece leaves a bP and a neutral piece leaves a nP unless 8 Pawns of that color are already on the board.

Royal piece: Фигура, которая выполняет на доске функцию короля.

Pser: This is the original definition by its inventor, Dan Meinking: A parry series-mover differs from a standard series-mover prior to the last move as follows:

1. the series-side may give check during the series;
2. when checked, the idle-side must immediately parry the threat;
3. a parry-move may be helpful or defensive, depending on the problem-type;
4. after a check-and-parry, the series-side continues the series.

Every Pser problem combines two stipulations:

Part 1 – Pser, which indicates the special series play with participation of both sides according to the author’s definition;

Part 2 – the kind of problem, according to well known stipulations, which can show direct play (n#, n=, s#, s= r#, r=, etc), help play (h#, h=, h==, etc) or mixed play (hs#, hs=, hs= =, etc).

Phser-#n: Pser problem where the parry-move is helpful (point 3 by Meinking) and the kind of problem is a Direct mate in “n” moves (Part 2 by Meinking).

Inspired by 620, but here with another stipulation, parry help series, the last brilliant conception of the late Dan Meinking. (Author)
