Hi Rob,
You missed my post - Crafty with random personality did play it (save for one
insignificant transposition).
In fact , the random settings are the basis for a the new "Najdorf" personality
to be released in the Crafty 19.12 SE update to be released this weekend.
Along with some other enhancements, some of which were contributed by Crafty SE
users.
* The new "Jekyll and Hyde" personality was changed to "Jekyll and Hyatt" to
honor, with a light touch of humor, the author of Crafty - Bob Hyatt.
* A new GM personality “Najdorf” that will play the mirror the moves if the
great GM Najdorf from 9….Bh2+ to the end of the game. (saved for one
insignificant transposition) if provided sufficient time. On my machine, 10
minutes was the max to find any one move.

1. d4 f5 2. c4 Nf6 3. Nc3 e6 4. Nf3 d5 5. e3 c6 6. Bd3 Bd6 7. O-O O-O 8.Ne2 Nbd7
9. Ng5 Bxh2+ 10. Kh1 Ng4 11. f4 Qe8 12. g3 Qh5! 13. Kg2 Bg1!! 14.Nxg1 Qh2+ 15.

21. Kxg4 Ne5+ 22. fxe5 h5#
* Crafty SE will now display the personality name in Arena and Winboard when
used as a winboard engine. It will also be picked up automatically in the pgn
file.
* "ranper" was fixed (did not work properly), changed (it is now a "krafty
extension" and will change every game (as opposed to every move). Most users
did not like it changing every move, myself included.
Example "krafty ranper 0 42" will select one of 43 personalities at random for
every game.
Example "krafty ranper 23 42" will select one of 20 GM personalities at random
for every game.
* The random settings selected by "Jekyll & Hyatt" personality ("krafty
jekyll" at the command prompt or crafty.rc file will now be captured at the
front of every log along with a "command string" for easy copying and pasting
into the crafty.rc file for further testing of new settings that look promising.
* A new randomness factor for the "Jekyll & Hyatt" personality that will act a
dial to increase randomness of up to 50% of piece values. The initial "Jekyll
& Hyatt" personality was a randomness of plus or minus 10% of piece values. The
use can now increase this up to 50% in increments of 10%. If you do not set it,
need not to worry; you will get the standard +- 10%. For randomness of +-20%,
you would use "krafty jekyll 20", +- 30% "krafty jekyll 20" etc up to 50%.
* The "Jekyll and Hyatt" personality will no longer contain settings for search
depth, so you may use this personality at the search depth of your choosing.
* A user may now override all or just a few of the random pieces settings with
your piece setting of you own. For example, say you always want to have the
queen valued at 900. Type "value queen 900" in the crafty.rc file or command
prompt and when you used "Jekyll and Hyatt" random setting personality, you will
always get the value for 900 for the queen. "value rook 500" would lock the
rook at 500 etc. All the other piece values will still be chosen at random.
* General improvement in feedback when using some of 'extended Crafty SE"
commands (both at the console level and in the logs).
* Look for the update in your mailbox this weekend. I will post here when
released.
Best,
Michael
