Re: Chess engine: Mantissa.

The solution ought to follow a similar pattern of place three bishops along the a1-h8 diagonal, then something like 1.- Bdf6, a6; 2.- Ba1, a5; 3.- B4f6, a4. Chest confirms that there are three moves that checkmate in 9 moves:

My line with 1.- Bdf6, a6; 2.- Ba1, a5; 3.- B4f6, a4 was also confirmed by Chest to be one of the many correct starts for a checkmate in 9 moves.

Here, try out this mate in 16, the only engines I found that find the mate in a reasonable amount of time are The Huntsman 1 (instantly), and SlowChess 2.9 (about 3 minutes)

This position screams Rxd5+. SF 15.1 was misleading me after few moves so I tried Rybka 2.2 (64-bit) from December 2006, which is embedded in Arena 2.0.1 GUI and spotted a checkmate in 14 moves immediately after the first two moves (four plies) from SF 15.1 were played. I cleared hash and tried more times later, always unsuccessful because Rybka 2.2 (64-bit) eventually sees the checkmate, but with more moves played. It can be said that the first Rybka analysis was really lucky. The first 17 plies (9 moves by white and 8 by black) are the only moves with optimal solution, then black can choose between two moves that equally lead to a checkmate in the same number of moves via transposition of moves:

Nice dance of the knights, like the homonym Prokofiev's piece music (Act 1, Scene 2, No. 13 Allegro pesante from Romeo and Juliet by Sergei Sergeyevich Prokofiev).

I would want to know the source of the problem, if possible. Thanks in advance.

Regards from Spain.

My fastest solver to deliver the mate in 16 was Crystal 6 PMT avx2.
Other solvers for M16:
Sting-sf-28-gcc
TheHuntsman1avx2
I did not try SlowChess-2.9
Taking ideas is not a vice, it is a virtue. We have another word for this. It is called learning.
But sharing ideas is an even greater virtue. We have another word for this. It is called teaching.
