Nf6+ Ke5 And we have reached the mate in 30 position previously posted. ( I think the position Volker took from the Rebel site simply went two moves into the Bwee study to give ordinary chess engines some chances). Thanks for posting the original source. I assume Gustav is a mate solver? Written by you? Is it availlable for the public or is it private? This position with the surprising mate delivered by the c-pawn is really beautiful IMHO.
