Dedicated test move......Mate in 9

[rightrook]

[d]k7/8/PP6/K7/4p3/2Rp4/2r5/8 w - - 0 1

Rc8+ is the move..

RISC.....3 seconds
Novag Sapphire II....56 sec.
Novag Scorpio.......1 min. 29 sec.
Mach 3................2 min. 16 sec.

Probably nothing out there faster than RISC.....only 3 sec.

Hi Rob
nice to see one of your positions for the oldies
been a long time...

i just happen to have the Mephisto MM VI already set up
it took Morsch's Engine 6 min.48 sec. to see the mate and play Rc8+ on the selective search mode
on its Brute Force mode it plays the move in 3Min.12Sec.

Slow As Molasses Regards

Hi Steve........Good to hear from you again..

yes, my TurboStar 432 does not find it ......even after 6 min.

so some may have trouble with this one...

Regards

Rob
