Please see 3 very different and very surprising problems by Peter Harris

No.195 – h=3  – А strange two-men! (JV)

No.196 – h#3  – A nice Orphan’s action! (JV)

No.197 -h#4  – A very surprising twin! (JV)

Definitions:

Anti-Super-Circe: After a capture, the side making the capture can place the capturing unit on any empty square. [Placement is compulsory]. A Pawn placed on its first rank is immovable.

Super-Circe – When captured, a piece is reborn on any free field on the chess board without causing self-check or selfmate. Possible is also removal of captured piece from the board. The Pawns (white, black, neutrals, half- neutrals) can be reborn on the first or eight row also. When reborn on the first row  (for Black) or on the eight row (for White) the promotion is obligatory. When reborn on the first row  (for White) or on the eight row (for Black) the Pawns are immovable.

Circe:  Captured units (not Ks) reappear on their game-array squares, of the same colour in the case of pieces, on the file of capture in the case of pawns, and on the promotion square of the file of capture in the case of fairy pieces. If the rebirth square is occupied the capture is normal.

Sentinels: when a piece (Ks included but not pawns) moves, a pawn of the same colour appears on the vacated square unless that square is on the first or eighth ranks or there are 8 pawns of that colour on the board already.

White Maximummer – Only White must play the geometrically longest moves, Black plays orthodoxal.

Maximummer – Black 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.

Orphan (O): An orphan can move only when observed by an enemy piece; when so observed it can move like the piece(s).

I’m sorry, I’ve made a mistake in No.196. It is corrected now. Pieces on the 1st rank are: R, B, S.
