Because you press the Piece1 or Piece2 buttons only once?
i think so

It would be a very nice feature to include bent riders. The gryphon mates but I'm curious for pieces like R2 then bishop and B2 then rook. I think they are both major (WD is major to my knowledge so probably R2 is too, B2 then rook could be trickier).
Why trying to define pieces I always get capture only pieces?!
I have noticed the general method. Thanks!
For larger board sizes you can try the general Checkmating Applet, upto 16x16. That also makes it more obvious what the general method is, for driving towards the edge, and then towards the corner.
Ok, thanks. It seems chessV in Grand chess cannot do it with small variantion. It probably does it with none, though! I tried that!

Use the "Try it" link in the Notes section, and start playing for black to see how it is done.
Does this piece and king mate a lone king? How? Is it similar to KNB vs K? Does it work on any rectangular board?
This game is very interesting and it makes an interesting candidate for the interactive diagram. Probably the stones may be somehow implemented by holes. I'm not sure how neutral would be implemented in XBetza, though!

Unfortunately it is not very easy to include the bent riders. For one, their retrograde moves are not the same as their normal moves. The current program assumes they are, and uses the same move generator for both. It would also raise the design problem for how to indicate the bent slides.
The current move-definition pane does allow you to define limited-range sliders such as R2, btw. Just define a regular Rook by clicking the W squares twice, and then for each paths click the H square to cut off the slide there. Usually the ability to jump doesn't have much use at this stage of the game; both WD and R2 can force checkmate in the same number of moves. It is just the statistics that changes a bit.
So R2-then-B can certainly force checkmate, as R2 already can. B2Z reaches a subset of the B2-then-R destinations, and it is also able to force checkmate. So I expect the B2-then-R to do it even faster, as the fact that it cannot leap directly to the Z squares should hardly hinder it.
