Why you SHOULDN'T post new variant suggestions + More endgame considerations on Chaturanga

Chaturanga kings on d or e file? seems like both was played

How is 2 player Antichess a mathematically proven win for White? Please give me proof.

Go to lichess analysis and play the best moves on each side, see who wins.

In catur, 2 Ferz and king vs lone king, same color or not, I'm pretty sure can force stalemate, granted that same color is rather difficult. I like the stalemated=loss rule, makes for some interesting endgames: winning with 2 ferz, or winning with 2 alfil+knight. However, as @nescitus said, bare king rule would be more historically accurate happy.png

horde is a win for white, but it has been added, and atomic is fair and fun, but it isn't still added

Both are acceptable for what I know. The real question is, does it affect gameplay in any way? If that was the case then I'd suggest we look up some sources to see if we can figure out what position was more popular historically. If the starting position is meaningless, then I'd say Chess.com can make that call, whether to leave it as it is or change it. Maybe you don't want to disorientate new players or somthing? Again, your call.

However, if I can give my opinion, gameplay change or not, I suggest we start with Kings on the d-file. The reason is that judging from the material and secondary sources available (from Wikipedia to shatranj engines) the game's "standard" position is with d-file Kings. This makes the game both easier to study with software (that the site might want to implement in the future for analysis) and gives the variant a unique trait, a quirk if you want, that makes it more memorable.

@Arma55, actually deciding about the king's file is main reason why I hold back with implementing a Chaturanga engine. The game is much more asymmetric than chess, given initial color complex advantage. e3-f3-g3-g4-Ne2-Ng3 is tabiya, whereas similar ferzside pattern looks silly, and evaluation function needs to take this into account.

@arma55, thank you very much for this topic. Interesting to read.

"Grey-area" and even some "wacky" variants are going to be added to Variants, because it is fun. Yesterday we added Giweaway chess (aka Antichess, aka Losing chess).

giveaway is the same as anti chess but with a different name

"aka" means "also known as" which is equal to "the same as ... but with a different name", but shorter
