I believe that if you give Huntman-1 3 to 4 hours it will find Mate in 13

I already tried it two times (letting it think overnight while I slept) to no avail.

It sees the key move 1.d4!! but only sees a mate in 15. The move it seems to be missing is 4.Nxf5!

I'll give it another try though just to be sure.

Ok, it sees 4.Nxf5 now after a few minutes, but it doesn't see 5.Bd4! now.

Crystal 8 (with contempt 100) does find a Mate in 15 with Multi PV but after 1400 minutes, one thread 512 MB hash, did not get further than depth 33 and still Mate in 15. I think I will close it down now :)

Debugging is twice as hard as writing the code in the first
place. Therefore, if you write the code as cleverly as possible, you
are, by definition, not smart enough to debug it.

I haven't had any engines solve this one yet, but I don't have every engine so I won't say that there isn't something out there that can solve it, I'll post the pgn later.

It's black to move but it's a forced mate in two for white.

The original problem seems insanely difficult. I gave it to Rybka, which is normally quite good at mate searches. It failed miserably and highlighted a bug in Rybka's search. This position is towards the end of the mate sequence. It finds the winning sequence but reports it as a draw. I assume it thinks white has insufficient material to win.

With 512 MB (one thread only, no Syzygy, no Use NNUE) the performance is maybe worse, I'm not sure. I certainly let it calculate long enough :)

Debugging is twice as hard as writing the code in the first
place. Therefore, if you write the code as cleverly as possible, you
are, by definition, not smart enough to debug it.

It misses the move from Peter Krug's .pgn 6.Bd3 even at this depth but if I make the move on the board (following the pgn with MultiPV =2), +M7 follows instantly:

Have a White to move and mate in 16 :

[d]3n4/8/pn1N3p/k1p2pp1/Pp6/3N1P1b/B3K3/2B5 w - - 0 1

I'll post a pgn later, however I'm sure it'll be solved before then.
