This is extremely unbalanced. An Amazon is only worth as much as a Queen plus a Knight, and the ability to castle or e.p. capture is of no significant value. So it is like black is three minors ahead, amongst which the Bishop pair.

For reference, Betza has a (unofficial/untested?) Chess-with-different-armies team with an amazon; he just limits the rooks to R4 and keeps the other pieces:

OK I've edited that

My submission is ready)

I see you equiped the Radioactive Queen with hit-and-run captures now. But would that not make it too strong? Can anyone beat the Diagram below with black?

I will remake this variant. Slightly

Ready for publishing. Hit-and-run captures activate only after adjacent taking move. So it’s like Lioness!

That does seem more reasonable. Although I still have my doubts that this ability would be enough to compensate for 3 minors.

Designing a viable asymmetric variant is far harder than designing a symmetric one. Because you have to worry about balance, which in the latter case is automatic, provided you take care of some minor points like a tactically quiet start position (e.g. no easily attackable unprotected pieces). To know whether an asymmetric game is balanced you really have to do extensive play testing, either by hand or through computer games. While you obviously never do any play testing at all.

I changed the move of the Cyberpiece in the Diagram I posted earlier to what you describe now. Can you beat the Diagram's AI with white now? Can you beat it with black?

I’ve beaten InteractiveDiagram with black and with white (I can send you move checklists). Don’t forget that white starts a game with SkyBrilliant’s drop, but black is the first player to move.

Something like Janggi

White places his Karmium on d1 and looks pleasant), so black moves first.

White places his Karmium on f1 to avoid white’s first sufficient move, black moves normally first.

Radioactive Queen Chess is long time ago considered as ready. Sorry, it’ll be nice to get your answer when you will be free.

I'd suggest to stick to one name for white's superpiece. I don't think "& be placed" is helpful in the description of that piece, nor including rook and bishop when it already moves as queen. Draw occurs if checkmate is impossible, but it's always possible for white if it still has its superpiece (?), and without it the game will already end in 5 turns?...

Thx very much, I've edited

So, can you change its short external description, like:

"White hasn't Queen and minors but places hybrid of all chessmen with hit-to-run adjacent taking"

edit: instead of "White has little diff in setup but..."

Before I do, can I suggest different phrasing?

White has no knights or bishops, but their queen is amazon plus a hit-and-run capture of adjacent pieces.

Sorry, I definitely refuse to call RQ as an amazon.

I’ve edited that article, now Karmium General can’t castle to Rooks, and winning rules are changed also.
