Most of my machines find...Rxf6 rather quickly;

however, i see that Fidelity computers (Mach3, Par Excellence..etc) have problems with this one...

RISC takes only 4 ply.....and 2 sec.

Cougar..............6 ply..............15 sec.

Novag Amber..........6 ply............55 sec.

Rob

I predict...that Mach 4 also has "problems" with this one....

Of course, it's the same program as the Mach 3, only 2.4x faster.

What time and ply depth did you get with the Mach 3?

Hi Terry....Mach 3...? Well, i gave up on it after about 4 minutes..

Also, Turbo 432 does not find it after about 8 minutes...but it does find it after about 45 or 50 minutes!

HI Rob

the Mephisto Montreal 68000 (same program as the Roma) finds Rxf6 in 27 seconds and a 2 Ply Brute Search (but 11 ply selective search)

And as you predicted ..the Excel Mach IV did struggle with the position but it does find Rxf6 after 2min. 29sec. and 6 Ply .
