Hello, Tanya! Thank You for this Gem!
Fritz6e does find Qxb3 on my computer but only after 37min. and some odd sec.
after searhing 17 plys deep; Level Fixed Depth which is faster than infinite
analysis. It can't find it at a 40/2hrs. obviously!:)
My computer is a bit slow by todays' state of the art hardware.
I'm using a PIII 500 with 128mbs of ram, 64 for hash.
Please tell me , at what depth of searh, (ply) Deep Fritz found Qxb3!
Also could you tell me how many min. and what platform (system + hardware)
you're using.
Becoming very interested in Deep Fritz, as time goes on!:) It think this
position will stump many programms. It's a great test position. Thanks Again!
Best Regards,
Terry
