• A: Alfil (2 step diagonal jump)
• H: Threeleaper (3 step orthogonal jump)
• C: Camel (3,1 jump)
• Z: Zebra (3,2 jump)
• G: Tripper (3 step diagonal jump)
• O: Fourleaper (4 step orthogonal jump)
• U: Zurafa (4,1 jump)

• J: Bonobo (5 step diagonal jump)
• R: Rook (W slider)
• B: Bishop (F slider)
• K: King (W+F)
• Q: Queen (R+B)
• Repeated Atoms: WW = Wazir Rider (Rook). NN = Nightrider.

Modifiers

• f, b, r, l: Forward, Backward, Right, Left
• ff, bb, rr, ll: Steep (only the moves most in that direction)
• v, s: Vertical, Sideways (only the moves most in that direction)
• i: Initial (first move)
• m: Move only
• c: Capture only
• e: En Passant
• n: Lame (cannot jump)
• j: Jump (leapers) or Skip first square (sliders)
• p: Hopper (needs hurdle, Cannon-like)
• g: Grasshopper (lands directly after hurdle)
• o: Cylindrical (Wrap around)
• q: Circular (Curve)
• z: Crooked (Zigzag)
• x: Explode (Capture all adjacent)
• w: Power Transfer

Further Syntax

• (x,y): Coordinate jump (e.g. (1,2) is Knight). (0,0) for null move.
• [Tag]: Attributes (e.g. [Immune]K, [Power]R)
• a: Relative sequence (e.g. FaR is Fers then relative Rook)
• -: Sequence (e.g. N-W is a Knight jump followed by a Wazir step)
• ?: Optional move (e.g. W?)

Combine modifiers before atoms (mfWcfFimfnD). Numbers after atoms increase or limit range (W4 = R4).
