For the 13th Sabra Composing Ty, we should compose an orthodox helpmate two-mover, where

B1 (first black move) : a black piece captures a white which closes a line

W1 (first white move) : a white piece, of line movement, arrives on this line

B2 (second black move) : the black piece, which made the capture, moves.

I made the following problem, with no distinction :

3bk3/3p2p1/3P2P1/4PP2/PrP5/1P5b/2K5/5R1B (10 + 6) | Problem-601 Manolas Emmanuel original h#2 a) Diagram, b) bKe8→c8 a) 1.Bxf5+ Be4 2.Bxg6 Bxg6# b) 1.Rxa4 Ra1 2.Ra8 Rxa8# Bicolour Bristol, Orthogonal - Diagonal transformation, Black sacrifices, Duels wB with bB, wR with bR. |

The Exercise is the following :

For the following position, (heterodoxe, because on d8 there is a Grasshopper), there are solutions when the bK is placed on squares e8 and g8.

Try to find a very economical modification (translocation or addition or removal of a piece), with which the problem has solution when the bK is placed on square c8.

### Solution of the exercise

The correct answer was send by the Slovakian composer**Jaroslav Stun**(visit his page here) :

a) bRa5→b5, which is the most economical, and

b) +bPb6

Thank you chess-friend Jaroslav!
