This position actually caused me to find a bug! Now with the latest build I have, it is solved, but Arasan is not as fast as some others - it takes about 95 sec. on a slower quad to find Bd5, and a long time to resolve it to mate (2nd col below is seconds):

Re: test position
Hello Arpad:
I gave a try to Komodo 3 w32 in my Intel Pentium D930 (2999 MHz) using 1 GB of hash:
[d]1N4br/3pkPp1/6PP/8/pp3P2/8/P4r1P/6K1 w - - 0 1
Taking a look on the mainline of depth 24 (and others), it looks like the mainline starts well; clearing hash and once again setting the same conditions for Komodo 3 w32 for this position (last move: Nxd7):
[d]8/3N1kP1/8/8/pp3P2/8/7K/8 b - - 0 17
(Negative scores from the point of view of the side to move, which is black, so positive scores for white). Around +5 evals (white wins) if Komodo 3 w32 starts analysing this position with an amount of time of less than 400 seconds (in my system).
Trying now Critter 1.2 w32 (2 cores) with 1 GB of hash and 128 MB for GaviotaTbCache (with the full set of Gaviota TB):
This analysis was interrupted at around 15 minutes with 552,571,671 nodes searched, an average search speed of 616,054 nodes/second and 3,364,930 TB hits.
It is interesting to note that Komodo realise that this position is won for white with less than 1.7e+6 nodes searched, while Critter needs more than 8.1e+6.
With the help of online 6-man Nalimov TB ..., b3 is better than ..., a3 by one move (mate in 24 versus mate in 23 if I am not wrong, which is very easy) if we follow the mainlines given by Critter 1.2 w32. So, Critter is almost right in my analysis... but starting from the initial position, I only saw Komodo give the right path, with the white king 'walking' for almost all the first row, and not getting sticked to f1 and g1 squares, although it is true that I did not let the engines analysing much time. Analysis on more powerful hardware is welcome, as usual.
Regards from Spain.

(Sorry for the long output of this post). The solution to this position is very easy to find in Internet (just copy and paste the FEN string in Google). For example, in ImmortalChess Forum, in the first spoiler of post #562 of this thread. (I suppose that it is the correct solution):Arpad Rusz wrote:A study by D.Gurgenidze (1974) featuring the same theme:

With the help of online 6-man Nalimov TB ..., b3 is better than ..., a3 by one move (mate in 24 versus mate in 23 if I am not wrong, which is very easy) if we follow the mainlines given by Critter 1.2 w32. So, Critter is almost right in my analysis... but starting from the initial position, I only saw Komodo give the right path, with the white king 'walking' for almost all the first row, and not getting sticked to f1 and g1 squares, although it is true that I did not let the engines analysing much time. Analysis on more powerful hardware is welcome, as usual.
Regards from Spain.
