series-helpmate in 19 moves.
In a series-helpmate, Black plays several moves consecutively to reach a position where White can mate in 1. Black may never put his own King in check, nor may he give check to White's King until the final move of the sequence (when White finally gets to move and can answer the check).

I guess I didnt understand the problem. What is series-helpmate? One solution for a helpmate would be
1. Nf3 Kb1
2. Nd4 Ka1
3. Ne2 e6
4. Nc3 d5
5. Rb2 e5
6. Rb1 mate
And I can see alot more than that. But I'm sure there is something wrong with it. 😕
It is not easy to find many checkmate patterns. I found one (black king on e6), but I need more than 20 moves for black to achieve it. Still work to do.

This would make 16 moves by black, am I doing something wrong?

Originally posted by crazyblueThe 'series' part of the stipulation means that, during Black's 19 moves, White does not move at all. White only moves once during the entire course of play (after Black has completed the 'series'.)
