Series helpstalemate in 36
(Series helpstalemate: Black plays n moves in a row, then White gives stalemate with a single move.)
Originally posted by crazyblueI generated the notation by playing through the solution with WinBoard. I shuffled the white Bishop from f7 to g8 to 'pass' for white. I tried to delete every occurrence of 'Bg8' and 'Bf7' in the notation, but for some reason, one of them survived.
Freaky! I was only looking for ways to block all black pawns, never thought that you gotta promote all of them to rooks. One question though: Isn't 20. Bg8 a white move? Didn't know that was allowed (not that it would have helped me to find the solution).
