Komodo 10 sees it also. Interesting shot that I would have missed as human for sure. :lol:

I've tested some DOS programs with your position. All programs running with maximum hash under real DOS at 3.3 GHz ,what is around 200 times faster than a 486 at 33 MHz:

Code: Select all

Socrates 3.0      11  00:01:27

M-Chess Pro 5.0   11  00:03:21

M-Chess Pro 6.0   12  00:04:02

WChess 1.05       14  00:06:43

Chess System Tal  13  00:09:50
These programs didn't find the move within 1.5 hours at depth:

Code: Select all

Fritz 3.05        17

Gideon Pro 1.0    14
