Yeah, and I'm thinking that a minimum of depth 60 is needed to get the solution?
@tn85N, hardware specs?

45 hours with MultiPV = 20. Hardware is i7-980x (6 cores). Approx 7-8M nodes/sec.
Reported ply is not always equal to the deepest search depth reached, so probably reported 60 ply is not needed.
Now, mate in 22 moves (8p & K & B(Q)), check comment #17.
For 1. e4 and 1. d4 lines.

How many chats? What a hubaloo!

I think this may be the reason we need Komodo or Houdini. at the time I reached the 13th move, I thought there must be better moves than 13 Qc5 and the other engine approved it. let us compare it:
Not necessarily. Stockfish 8 currently at ply 33 (...). As it will go deeper both the moves of 1-12 and above 12- will probably change.
I update the above results continuously.
