DAN+, Different Augmented Knights

An Augmented Knight is an ordinary Knight to which a simple extra power is added. It is ever so slightly stronger than a Rook, except that the Rook might possibly be stronger in open endgames with pawns on both sides of the board.

Standard Augmented Knights

There are four standard Augmented Knights, fully tested and approved for tournament play.

NA

A two-square diagonal leap is added to the power of the Knight; for example, from e4 the NA can go to f6, g5, g3, f2, d2, c3, c5, d6, g6, g2, c6, or c2, in all cases either to move or to capture.

It can go from e4 to c6 even if d5 is occupied.

NF

A single diagonal step is added to the power of the Knight; for example, from e4 the NA can go to f6, g5, g3, f2, d2, c3, c5, d6, f5, f3, d3, or d5, in all cases either to move or to capture.

ND

A two-square leap in the Rookwise directions is added to the power of the Knight; for example, from e4 the NA can go to f6, g5, g3, f2, d2, c3, c5, d6, e6, g4, e2, or c4, in all cases either to move or to capture.

It can go from e4 to e6 even if e5 is occupied.

NW

A single step in the Rookwise directions is added to the power of the Knight; for example, from e4 the NA can go to f6, g5, g3, f2, d2, c3, c5, d6, e5, f4, e3, or d4, in all cases either to move or to capture.

Experimental Augmented Knights

Many other pieces have the same theoretical value as the Augmented Knights, and can be substituted in place of them.

These pieces are still experimental.

LW A single step in the Rookwise directions is added to the power of the "long Knight"; for example, from e4 the LW can go to f7, h5, h3, f1, d1, b3, b5, d7, e5, f4, e3, or d4.
The LW is experimental, but very likely to become standard.
[August 1996] Reject LW because of instant win: 1. (LW)a1-b4; threat (LW)b4-e5 wins Queen; threat (LW)b4-b5 wins Ra8.
NH A true Augmented Knight, with the added power being simply one step further than the ND; for example, from e4, the added power goes to e7, h4, e1, or b4.
The NH is experimental, but likely.
WFA Moves like a King with an added two-square diagonal jump; from e4, it leaps to e5, f5, g6, f4, f3, g2, e3, and so on.
HFA From e4, to d5, f5, f3, d3, c6, g6, g2, c2, e7, h4, e1, or b4; highly experimental.
HWD A three-square X-Ray Rook, in effect; from e4, it leaps to e5, e6, e7, f4, g4, h4, e3, e2, e1, d4, c4, or b4.
Highly experimental; very clumsy in the opening, very deadly once it gets its opportunity.
