A thought to help eliminate doubleteam checkmates in FFA

If 2 or even 3 players take part in a mate on a single player, instead of giving 1 player all 20 points,  split the points between the 2 mating players. ( or 3 @ 7+7+7 ) A backrank mate involving rooks of 2 different colours ( or queens ) covering the backrank and the 2d rank would be split 10 points each. Additional points for captures would remain the same.  An open field checkmate would likewise be split, 2 players involved, 10 points each. If a capture is involved, those points would remain the same. And if 3 players were involved, 7+7+7.  I'm kind of proud of myself for this one, so excuse me if I think it's a really good idea.

I think this has been suggested before, but in a more fair way: the player who controls the most escape squares gets the most points. So for example, if two players, red and yellow, checkmate green, and red controls 4 out of 6 escape squares while blue covers 2, red gets 13 points while yellow receives the remaining 7 (20 divided by 6, then do the rest of the math yourself ). This might not work completely since you also have to consider if someone took a piece that could potentially block a check or capture a checking piece. But yeah, cool idea overall.

So let's say that you give a support mate, with your queen, with your bishop supporting your queen. Then you give checkmate to a player, and the square you put your queen on happened to be controlled by another player's bishop (you are red, the person u checkmated was green, and the person who controlled that mating square was yellow). Do you get the full 20 points, or does yellow protecting the mating square mean that he gets a share of it too?

I'd say you controlling all the escape squares except the one square your queen is on means you get most of the points? But then again, without the bishop the mate isn't possible, so idk, lots of consideration to be done

You do have to consider user-friendliness though...

I feel like this is a better idea for an additional rule/variant, but to make it standard would change to much theory I think...

i was talking about the scenario where 2 bishops were controlling that mating square (BOTH red AND yellow's). If THAT's the case, then what will happen? Does yellow get anything for happening to control that mating square where it was protected by red's bishop anyway.

Not so sure about. It's much more fun if you can suddenly steal the mate from other players.
