Robert,
That is puzzling. Are there value gaps between the other augmented Knights
or do they test out fairly equal? Value of NF vs. R I could argue either
way as their moves are so unrelated.
I would think that the NF would be the strongest augmented Knight (even
though less mobile than NW) as it masks two Knight weaknesses:
colorswithching and inability to move a single square.
NW masks one step inablility but isn't as forward as NF.
NA and ND mask colorswitching and give a a lot of coverage to the 2-square
distance. These are very likely quite well mathced: NA more forward, ND
more mobile.
I really never had though of colorswitching as a major disadvantage, I
have even doubted it is worth considering. On the other hand one of the
nice things about Rooks is that they are neither colorbound nor
colorswitching.
