Banzai Chess. Friendly pieces can be pushed and pushed pieces can bounce. (8x8, Cells: 64) [All Comments] [Add Comment or Rating]

I think it's ready to be published.

It would be an interesting challenge for someone to make an Interactive Diagram for this variant.

Pushing does appear in other games, of course (a couple of pieces in my own Zwangkrieg do it), but I don't think I've ever seen the idea applied as uniformly as this, nor explained as neatly, clearly, and elegantly. It makes me wish that there was a simple code one could add into XBetza for doing it.

It is not the pushing that makes that difficult, but the rule that Pawns have a double-step from the first rank. (That they regain the possibility when returning to 2nd rank can be indicated by making it an ii move.) I suppose it could be done through a morph for the Pawn that forbids access to the enemy half, but then exempt the fmW and fceF moves from that, so that only the fmnD move suffers.

The pushing is not too complex: hop on a piece (d), land on the empty square immediately after (af or yaf), and then step backward for friendly capture with unload (i.e. swap, abud). The bounce rule is implemented (on diagonal moves only) by landing off-board after the hop, returning backward for a second hop, this time hopping off sideways, and swap from there (pyafoabpasabudB).

Thanks for your comment! I'm glad someone else enjoys this variant.

If you're into even more complex games like the one you created, which seems pretty crazy to me, I suggest trying the sub-variant of Banzai. I haven't settled on a name for it yet (that's why there's no page about it at the moment).

Basically, everything remains the same, but you can push multiple pieces with a single move instead of just one. You'll be amazed at how this single change not only increases the complexity but also enhances the enjoyability of the game.

I was thinking of calling it Zero Gravity Chess, abbreviated as 0G, but I'm still not sure about the name. Any suggestions would be greatly appreciated!

That's actually a feature (at least, very similar) I wanted to give the Barbell for my Clue variant. I felt like the XBetza would've been prohibitively complex — not that XBetza has any bearing on a game with up to eight players, of course, but I'd want to have the piece available to other games.

BTW, in case anyone cares enough to wonder, I decided on the Axe for the eighth weapon in Clue Chess.

Zero Gravity Chess does seem to me like a good name for a 3D version of this. My ideas for this:

  • Archimedes Chess
  • Sliding Puzzle Chess
  • Pushover Chess

Thanks for your suggestions!

I really like Archimedes Chess but unfortunately there is already a variant called like that. Which seems to be the case with almost any name I can come up with...

Maybe I'll just call it banzai 2.0, banzai unbound or something else along these lines.


Bob Greenwade wrote on Thu, May 9 02:57 PM UTC in reply to Vincenzo Rapisardi from 01:11 PM:

Perhaps Archimedean Banzai, or Domino Banzai?


💡📝Vincenzo Rapisardi wrote on Fri, May 10 03:19 PM UTC in reply to Bob Greenwade from Thu May 9 02:57 PM:

I had already thought about Domino Chess and I do like Domino Banzai. What do you think about Hyper Banzai or Accelerated Banzai?


Bob Greenwade wrote on Fri, May 10 03:54 PM UTC in reply to Vincenzo Rapisardi from 03:19 PM:

Hyper Banzai is a fairly decent descriptor. Accelerated suggests something different.


💡📝Vincenzo Rapisardi wrote on Fri, May 10 05:52 PM UTC in reply to Bob Greenwade from 03:54 PM:

Thanks! I think I will stick to Hyper Banzai for the moment. Do you think is it okay to not explain again the rules (since they are already described here) and just link this page? Because in this way I can simply tell where is the main difference and then show it with only few images. Like this


Bob Greenwade wrote on Fri, May 10 08:00 PM UTC in reply to Vincenzo Rapisardi from 05:52 PM:

I think it would be better to cut-and-paste the rules. If the differences are so slight, it probably would be better to just make this a subvariant on this page.


💡📝Vincenzo Rapisardi wrote on Fri, May 10 08:56 PM UTC in reply to Bob Greenwade from 08:00 PM:

You are correct. I can describe it here, but unfortunately I can't put any more pictures on this page. That's why I'm probably going to describe the rules, just more briefly, on the other page. Thanks, again, for your wise suggestions!

That is amazing! Thanks! How can I implement it inside the main body of the page? Just thinking about those who may access it from their smartphone, which are very unlikely to check out the comment section!

I tried to recreate the same Interactive Diagram with the Betza notation you used but I got some troubles with the pieces' image... How do I get to know their filenames?


HaruN Y wrote on Wed, Jul 10 12:15 AM UTC in reply to Vincenzo Rapisardi from Tue Jul 9 06:13 PM:

Thank you're welcome! For the pieces' image, you can either view the page source or click the underlined here then tap and hold the piece image then open image in new tab.

Note that my implementation is not accurate with the rules written here. Moving a pawn using another piece to a promotion rank does not promote that pawn, instead the pawn gains Rook moves.

Thanks again! I finally managed to resolve the issue with the images. I noticed the thing with the push-promotion but I'm totally fine with it. I don't think there is a way to allow the users to choose the promotion piece, and even if there was I don't believe it is that important in this particular case :)

EDIT: I found out that it is possible to choose the promotion piece, but I'm not sure if it is possible to implement this option for a "push-promotion".
