Must Capture Pieces Rule Suggestion

I have a suggestion for a rule that could be added into 4 Player Chess & Variants. It would be called "Forced Captures" and means that when one player is able to capture a piece(s), they must choose the piece they want to capture and capture it if this is a legal move.

Special rule: However, if a player is in check but attacking enemy pieces and cannot capture anything legally, they lose the game. (Or you could turn on Capture the King and disable this rule.)

This would allow for variants such as Chess but you have to capture when you can (different than Giveaway) and other cool variants.

Do you think this could be added in the future?

This is giveaway+bare piece, right?

nice, I wish they will make this happen

Interesting Idea!

Is there a specific example of this gamerule being used that would warrant its addition (e.g., a historical variant, or a new idea), that Giveaway/Antichess can't?

Thats basically giveaway but with legal moves

Sure, using this gamerule applied to Standard Chess is a new idea and by the way, has also been mentioned before:

https://www.chess.com/clubs/forum/view/compulsory-capture-variant. (@spacebar, a chess.com staff talked in here too).

Giveaway is pretty different from this variant because in Giveaway, although capture is also forced if possible, in Giveaway, the king can be captured, you can promote to a king, and also the goal of the game is to give away all your pieces. This allows for strategies in which players make sure their pieces don't have too much scope because otherwise, the opponent would lose tons of pieces. However, using the new gamerule idea in Standard Chess is different because the main problem of pieces having too much scope is when it's attacking a protected piece. This creates a very different strategy compared to in Giveaway. In Giveaway, (according to Fairy-Stockfish,) pieces are a lot more aggressive and moving all over the place while this game's strategy makes sure pieces are limited in movement (not too limited though).

Also, this variant doesn't require that much knowledge about opening theory. This variant is probably:

- 15% how good you are at the new gamerule

- 40% how good you are at Standard Chess

- 45% new variant's opening theory, priniciples, endgame principles, etc.

As this variant is basically Standard Chess with a simple twist, the people who play it probably enjoy Standard Chess. So, they can partially use their Standard Chess skill and partially learn more about the new variant's opening theory, principles, etc. to get better at the game, which seems like a good balance.

Also, if you want to look, I linked my studies on this variant. It might not be that accurate as I came up with it myself (not Fairy Stockfish) though, but it's definitely reasonably correct:
