Introducing the Samnis, which combines rook-capture with bifurcated bounce-movement, on a Gustavian board (zrf available).[All Comments] [Add Comment or Rating]

I don't see any explanation of how the Samnis bounces from the board edge...

But with shuffle.

Samnis can't get out if it can't use the edge of the board as a screen.

Imagine an outer ring of immobile pieces put around the board. Any of those virtual pieces can act as a bouncer. The Samnis can be bounced from the board edge when the first leg of the move is tangential to the edge.

OK, I see. The Diagram should be able to implement that by allowing an off-board screen.

I didn't know there were 'winter' pieces on this website, BTW. This will be useful to mimic the original diagrams better.

There is still one thing that is not clear to me: does the Samnis test for a screen purely sideways from its initial R leg, or does it test along a backward F step? I.e. in the diagram below, would the Samnis at e4 be able to also move to g5-h6 and c5-b6-a7 (due to Pe3), or just to b3-a2 and f7-g8?

As I understand it, yes, it can. It moves one step orthogonally an receives a bounce on that square. One orthogonal step is sufficient for the first leg of its move.

From the example of a similar piece, it's likely that what Jorg said was true. There's also zrf.

Also why not use 'winter' graphics?

Interactive diagrams is a good idea, but it's too ambitious for my site, which receives few visitors. This should answer your question about the Samnis:
