Nf5 is played because of positional evaluation apparently.
While I don't disagree that it seems to be a winning move, it takes Fritz7
running on your 4.66Ghz computer quite a long time to see that it is winning by
more than a few centipawns (same for CT15 BTW).
So I'm not sure if this position can be considered as an interesting test.
