I mean, he makes a couple of moves but in the end has the same position as at the beginning.
Bonus points if castling is involved. :-)
In selfmates it is called the Weber type, and in orthodox problems it is called "zugwechsel".
Example (original), created in a few minutes (EDIT: Position corrected):
(= 6+5 )
ser-r#2
Promotion to dummy pawn allowed
1.a8P? 2.???
1.a8S/B/R/Q? 2.Sb6/Bc6/R:a6/Qc6,Q:a6 mate
1.S:a3? 2.Sb1 and Black has no mate
1.Qb2? 2.Q:a3 mate
1.Qc3? 2.Qa5,Qb4,Qc6 mate
1.Qe5? 2.Qa5 mate
1.Qf6? 2.Q:a6,Qc6 mate
1.Qg7? 2.Qd7 mate
1.Qh8! 2.Qa1! B:b3 mate
And while you're here anyway, please post further examples (fairy chess welcome!). | | (2) Posted by Olaf Jenkner [Saturday, Jun 11, 2016 22:17] | What about 1. Qh8 2. Sc3# ?
Or 1. Sc3# ? | | (3) Posted by Sarah Hornecker [Saturday, Jun 11, 2016 22:26] | Oops, I had Pa5 on a6 first but then thought it is better on a5 to make some lines better. I will correct the OP. | | (4) Posted by seetharaman kalyan [Sunday, Jun 12, 2016 08:38] | Well... it has to be series reflexmate or series reflexstalemate. It has to be a switchback. I wonder if better term than 'silly problem' can be found. | | (5) Posted by Sarah Hornecker [Sunday, Jun 12, 2016 13:55] | I can imagine that it works nice if the pawn is the piece that eventually returns. | | No more posts |
