Both you are Uri are obviously right.
Your explanation is the simplest.
It makes it crystal clear instantly that black is lost.

14x the nodes of Eelco's analysis failed to throw more lights on the matter.

This was going to be a d=50 analysis but a blackout cut it short in the sixth/seventh hour. Seeing how the PV starts to get irrational as early as the fourth ply - 2...Kc8 (?!?) - I doubt d=50 would have provided any additional revelations.

BTW, this is master trunk; ASM is too clever to accept this FEN.

using mcbrain with matefinder option on seems a lot slower. took me 34 ply, almost 13 billion nodes to find mate in 28. while you find a mate in 29 using just over 28 ply,2 billion nodes.

anyone any idea if I was setting it up wrong ?

Re: how much time do programs need to find a forced mate

using mcbrain with matefinder option on seems a lot slower. took me 34 ply, almost 13 billion nodes to find mate in 28. while you find a mate in 29 using just over 28 ply,2 billion nodes.

anyone any idea if I was setting it up wrong ?

stockfish 8 seems to be a lot quicker than mcbrain at finding mate. it is 27 ply, 3 billion nodes.

Re: how much time do programs need to find a forced mate

No mathematical proof but a possible plan that convince me that it is mate is simply to trade pawns and KQRRBBNN vs king and 8 pawns is a simple mate when the pawns are not advanced.
what about all the pieces against 24 pawns. is that mate.?

crafty self play can defeat 32 pawns, although I cannot assess its play to see if black should be playing better.

game is faulty as do not know how to display games properly
