series helpstalemate in 41
Black moves 41 times in a row; white stalemates in one. Black avoids checking until final move of sequence.
Difficulty: Hard.
I tried cooking this, but it looks to be sound.
It looks like everyone burned out on series problems. I'll post the solutions soon unless someone is still trying to solve.
