A nice stroke by HIARCS. Rybka sees Rxf3 after Nf3. Maybe a null move problem?
I'm not qualifed to say. Maybe Rybka given enough time will not play Nf3.

My computer is slow and would take some time to see if it would avoid Nf3.

Also interesting if HIARCS were White, if it would avoid Nf3...could it also
need a longer search to avoid this blunder? I don't have HIARCS 10 so I don't
know.  The Best HIARCS I have is H9. Of course I could us H9 in place of H10 but
it isn't the best way to check, as it's an older ver. IMO
