Warm welcome to Kjell Widlert – a noted Swedish composer, editor of “Springaren” magazine and also the last time one of the best commentators on JF! Two problems by Kjell have an uncommon fairy conditions and minimal white material:

No.512 – ser-h#6 with Haan Chess (HaanerChess in Popeye);

No.513 – h#12 with Alphabetical Chess. (JV)

Definitions:

Haan Chess : Any square left can’t be neither occupied nor crossed.

Alphabetical Chess: The squares are considered in the order a1, a2…a8, b1…b8, c1 and so on to h8. At each turn, only the unit standing on the square which comes earliest in this order may move. However check and mate are normal.

Kc3 3.Kc6 Kd4 4.c1B Ke5 5.Be3 Kf6 6.Kd5 Kg7 7.Bf5! Kh8 8.Ke4 Bxf5+ 9.Kf3 Bg4+ 10.Kg2 Bh3+ 11.Kh1 Bg4 12.Bg1 Bf3# (C+ WinChloe) Corner-to-corner walks by both kings. The white walk is motivated by the need to activate Bh7; the black walk is motivated by the fact that there is no mate on a8. The problem was composed in a few days over the New Year’s holiday in a friend’s summer house on the West coast of Sweden. He was impressed when I showed him what I had done, although he doesn’t know much about chess problems. (Author)

512: 2 ideal mates in the middle of the board that took me half a minute to solve but left an impression that will last forever!

The idea of No.512 is shown in some Sentinelles problems.

Yes, the effect will be the same.

It is true that leaving a hole behind or leaving a pawn behind will often have the same effect. But not always!
