# A Circe Chess problem - 1: Solution

Stefanos Pantazis, editor of The US Problem Bulletin, has sent me two problems that appeared in that journal and did win a prize there.

This is solution of the first problem: You can also look at the second problem: a helpstalemate in 4 moves.

This problem was composed by George P. Sphicas, was published in the US Problem Bulletin in 1993, and won a Second Prize.

White:
King d4; Pawn d2, e6, h4.

Black:
King g4; Queen g5; Knight f2; Pawn f7, h6, h7.

Circe. Series-selfmate in 17 moves.

(b) Move the black knight from f2 to h5, and solve the problem again.

## Solution

The comments can be ignored, but may help to understand the notation.

(a) The solution of the first part is:

1. e x f7. Black pawn is not reborn because square f7 is occupied.
2. f8 =Q. Pawn promotes to Queen.
3. Q x f2 (Nb8). The black knight is reborn at b8.
4. K d3.
5. K e2.
6. d4.
7. d5.
8. d6.
9. d7.
10. d8 =Q. Pawn promotes to Queen.
11. Q d1.
12. h x g5 (Qd8). Black queen goes back to d8.
13. g6.
14. g x h7. Black pawn is not reborn because square h7 is occupied.
15. h8 = Q. Promotion to queen again.
16. Q x h6 (h7). Pawn is reborn at h7.
17. K e1 +.
17. ..., Q x d1 mate. Only legal move of black gives mate.

(b)The solution of the second part is:

1. e7.
2. e8 = R. Promotion to rook.
3. Re3.
4. Ke4.
5. d4. 6. d5. 7. d6. 8. d7. 9. d8=R. Promotion to rook again.
10. R d4.
11. h x g5 (Q d8). Rebirth of queen on d8.
12. g6.
13. g x h7. Again, pawn disappears.
14. h8 = R. Promotion to rook.
15. R x h6 (h7). Pawn rebirth on h7.
16. R x h5 (Ng8). Knight rebirth on g8.
17. K e5+
17. ..., Q x d4 (Ra1) mate. While the rook is reborn on a1, this only legal move of black gives again mate.

## A cook?

The problem couldn't be computer tested, and the possibility of a cook (additional solution, shorter solution, ...) cannot be ruled out completely, but seems not too likely. Any reader finding such a cook is requested to contact me.
