I think the rules were clear, just that Betza notation does not describe it unambiguously. Though it seems reasonable to interpret crooked moves as continuing in the outwardmost direction by default, unless otherwise specified, in which case t[WzB] would indeed describe the Harvestman (the other option is then not covered by the original Betza notation, though something like t[WfhzB] would probably be clear enough)

The Harvestman goes only in the direction that is strictly incresing the distance from its starting field. I never intended it to take the sidewards turn that increases the breadth of the covered squares from 3 to 5. But I see that one can read the description in such a way that this kind of move were also allowed.

Original Betza notation was not precise enough to unambiguously indicate this piece. The problem is that even when it is understood that the continuation as zB after the W step should be outward, it is not clear whether the next bend should be in the same or opposit direction.

XBetza currently also cannot describe this piece in a simple way. (It is of course always possible to split up a slider move into a set of lame leaps of various distances, and mention each of these lame leaps and the path they take separately.) Introducing repeats on groups of modifiers would solve it, though. The half of the Crooked Bishop that starts bending to the left is FalFalarFalaralFalaralarF..., and this could be abbreviated to (alar)F(alar)alF if parentheses would be taken to mean zero to arbitrary many repetitions of the enclosed group. The corresponding half of the Harvestman would be Wafr(alar)Wafr(alar)alW.

if I'm not mistaken, it would be [WzB]

if I'm wrong, please correct me, I don't know fully get how to represent bent riders

what is betza notation for the Harvestman?

Georg Spengler wrote on 2015-01-10 UTC
Ah, that was stupid. They bet blocked by the pawn. My wrong.

The opposing Genschers can get exchanged in the starting position. That's ugly.

Shouldn't they better be put behind the sea?

This is another forward reference: the harvestman ist one of the many pieces featured in Carlos Cetina's UC-170-13.

This is a forward reference to X Chess by Jeremy Gabriel Good

where many pieces of Seenschach are set on another innovative hourglass shaped chessboard.

This is a pretty variant. I should try it some time.

A coment on my note: of course, the reflecting bishop of the
second kind was described earlier, and there is even a third
kind of it, with the mirror half a square beyond the border
of the board. They are all described by Ralph Betza in his
article on Billard chess on this server.
