In recent CCRL D8 match between Myrddin and Luna:
[d]
2b2k1r/bp1p2p1/r1pP1pB1/7P/4NP2/3R3R/1p2P3/1K6 w - - 0 28
One surprising move leads to Mate in 10, and Myrddin finds it in 1.6 seconds.
Enjoy!

Re: Mate in 10 test for Amateurs < 2700 (and humans!)
Interestingly Stockfish development version need 3 min 30 secs to find this, running on one core. Maverick finds it in 1.8 seconds, The King 3.5 finds it in less than one second. (i9 laptop)

Re: Mate in 10 test for amateurs < 2700 (and humans!).
Hello:
Summary:
-----------------------
Chest 5.2 needed almost four minutes on my desktop (hash = 256 MB) to find the checkmate in ten moves and more than six minutes to find that this move was the only move to checkmate in ten moves:
------------------------
Hermann 2.4 64-bit did an excellent job:
------------------------
Nejmet 3.07 was a little slower than Hermann, but finally succeed:
------------------------
Ruffian 1.0.5 also did an excellent job, like Hermann:
------------------------
Rybka 2.2 64-bit was even faster (less than a second!):
Although the complete checkmate is not shown.
------------------------
SOS 5.1 for Arena also found the checkmate in ten moves. It was the slowest engine on my desktop (Chest aside):
------------------------
Finally, AnMon 5.60 and Dragon 4.6 found the best move in few seconds with winning scores, though evals raised slowly. ProDeo 1.5 showed a similar search pattern, although switching between 28.- Rde3 and 28.- Rhe3.
Regards from Spain.

ProDeo 1.5 showed a similar search pattern, although switching between 28.- Rde3 and 28.- Rhe3.
