It must not be that easy for white to convert 6...Nxd5 into a win, since Toga II
lost in a quick game continuing from that point on my computer:
[Event "Computer Chess Game"]
[Site "GREG"]
[Date "2006.01.09"]
[Round "-"]
[White "Toga II 1.1a"]
[Black "Rybka 1.0 Beta 32-bit"]
[Result "0-1"]
[TimeControl "40/600"]
[Annotator "8. +0.33 7... +0.85"]

In analysis, Rybka beta does switch from 6...Nxd5 to 6...O-O at depth 19.
