I propose a piece which I dub Stag Unicorn (will change the name if it's already taken).

Every time a move is made in the bishop direction, an optional knight move can be played - if bishop is moving right, it can do (has the option of doing) an additional knight move according to the pattern described below....

Let me try using the compass rose to describe this piece.In the diagram below, ferz travels to NW1, NE1, SW1, SE1; Alfil travels to NW2, NE2, SE2 and SW2. Wazir to W01, S01, NO1, E01; Dababa to W02, N02, S02 and E02. Knight travels to NNW, NWW, SWW, SSW, SSE, SEE, NEE and NNE. 



 NW2   NNW   N02   NNE   NE2

 NWW   NW1   N01   NE1   NEE

 W02   W01   SUN   E01   E02

 SWW   SW1   S01   SE1   SEE

 SW2   SSW   S02   SSE   SE2

The stag unicorn is a bishop which can make an additional (optional) knight move in one of two directions along its route. If he is traveling NorthWest (NW), he can make an additional knight move to either NNE or SWW. Traveling NE, he can move to NNW or SEE. Traveling SE, he can move NEE or SSE. Traveling SW, he can move to SSE or NWW.

In the diagram below, this is illustrated with the numbers 1 for the first square (the ferz square) it has the option of going to and 2 for the second square it Stag Unicorn has the option of going to: 


b o o n o n o o b o 

o b o o 2 o o b o o 

o o 2 o o o 2 o o n 

n o o 1 o 1 o o n o 

o 2 o o B o o 2 o o 

n o o 1 o 1 o o n o 

o o 2 o o o 2 o o n 

o b o o 2 o o b o o

Note: Stag unicorn must be able to travel first to the bishop square before traveling on to the knight square.

Anyone familiar with this piece? Has it already been invented?

If I'm not mistaken, the Diagonal Wide Crooked Nightrider(dwcn) described in Nachtmahr (under heading, 'On file F') covers the same ground as the Stag Unicorn I propose only in reverse (going to the knight squares first). I therefore propose dubbing this piece, dwcn, 'Mare Unicorn.'

In my piece article MAB 09: Mighty Like a Rose I devised names for Nachtmahr's Crooked Nightriders. They are, with starting files in brackets:
Longnightflyer (h);
Shortnightflyer (a);
Longnightsidler (c);
Shortnightsidler (f);
Nightdueller (g).
All these names can of course be extrapolated to Crooked riders of other oblique leapers.
