# 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.
