Suggestion: Checkmate in 4 Player Chess

I propose a solution of the "Checkmate in 4 Player Chess" problem. 

(This is a separate topic is to focus on the checkmates only. Some ideas were discussed here: 
https://www.chess.com/clubs/forum/view/new-checkmate-dead-king-rule )

The solution is to consider the checkmate as the end of the game for the checkmated player, but give +20 points to the player which actually captures the king.

An example:
1. Red checks the green king. No points awarded (if it is not a check to 2 or 3 kings at the same time).
2. Blue attacks the square(s) of the escape path and/or checks the green king, so we have a case when 1) the green king is under a check (by red or by both red and blue), 2) green king does not have an escape path, 3) green player can not remove both the threats by a single move.
3. Yellow makes some move that does not change the green's situation.
4. At this moment (at the beginning of green's move) this is considered as a checkmate. As a result the green leaves the game, all his pieces except his king become gray. The king stays on the board and can be captured.
5. Red (or blue, or unlikely yellow) capture the green king and get +20 points.

This way we keep the chess spirit in this game and also resolve the problem "who should get those +20?"

Some modifications are possible, of course. For example, we can give some bonus (+10?) to the blue at step 4. And currently step 3 does not work (the server does not wait for the yellow's move, that is strange in my opinion).

makes a lot of sense. but will it be more fun than what we have now? i love all the funky mates and the challenge not to give them to your opponents.

concerning stalemate, when there are only 2 players left standard chess rules would make sense (the stalemate-bug topic).

i think 4pc checks for check- and stalemate for all 4 players on each move.  it doesn't matter if it might no longer be mate (or stalemate) on the mated players turn. you might expect this for stalemate, but for mate?

 

here's a game i observed. how would changing the rules affect play i wonder?

null

red took greens h3 pawn thanks to a pin. blue then checked on g2 using the red bishop as cover. Kh1 by green. red's discovered check isn't mate as green could now take the rook. (blunder by red!)  blue then mates by pulling back the rook (green cant block)

one could wait for greens turn to determine if he's mated (yellow can still interfere). but now who gets the points?

how about: capturing the king gives you the value of his armies remaining pieces? at best  9+5+5+5+5+3+3+8 ~ 40 points.   if you sit back and wait there'll be nothing left to get!

Sorry, in your sample I could not understand where were the pieces before. Could be better to have some notation like blue moved his rook g8-g2 (the red bishop was at ...) then red moved the queen g8-h8. As I understand, the top right square is h1.

P.S. "How many points" is another topic.

red takes greens h pawn thanks to the pin by blue rook (down on the other end..)

null

then blue takes on g2+, green stept into the corner, red discovers the bishop (see above), and blue pulls back rook for mate.

as to your suggestion, in this example, red would get to pick up the mated king, which i don't think as much fairer because red didnt mate him.

Stealing mate is so much fun though tongue.png

here's the position. yellow and blue proceeded to overcome red !

i love this game because you really cant judge the outcome by a position, it all depends on the alliances, which might change on any move. its jus nutz!!

I hope I did not miss understand the suggestion. Assuming I got it right I would offer that we leave it like it is (or similar) for reasons stated already OR change it to points giving to king once taken (checkmates are eliminated and players can move anything while in check). The suggestion above somewhat heads this way but allows the safety of their pieces and not sure you should get that lucky if you want it more for the person that should be the one to kill the king then make them kill the king and lose the piece doing it to the next player. If you want the slyness of figuring out how to avoid losing your piece while getting the points leave it as is and accept the risk that someone might out move you and steal your work/points

 In the position above the yellow player could not change the situation. So, it is a checkmate according to both the current rules and the proposed rules. Yellow could not eat the red queen (which checks the blue king), yellow also could not put any piece between the red queen and the green king. The difference with existing rules is: Green army will stay green till the beginning of the green's move. Now it turns gray immediately after the blue's move.

+1 this is the key for me, I like the current rule

My suggestion does not remove the possibility to steal a checkmate.

Avatar of Skeftomilos

Yea, but stealing a checkmate will not reward you with points, according to the suggestion. The points will go most probably to the player who delivered the first check, since he now has a piece directly targeting the dead king. This is not funky!

It seams that almost everyone would like for the standard version to include a wacky rule, or two, but the tastes about the exact kind of wackiness differ widely. :-)

From today's chat: "Someone know where we can say the errors to improve the game? The thing is that I was green player and checked the yellow one, in the same turn the blue one put his piece in order to enclosed the yellow king and that produced a checkmate but the blue gained the points instead of me".

People just do not understand the current checkmate rule.

The solution is to consider the checkmate as the end of the game for the checkmated player, but give +20 points to the player which actually captures the king.

A good case for your suggestion, but one must also counter the natural case for points going to Yellow, namely Yellow is the last to move prior to Green being judged to be in checkmate.  Yellow has options.  Some options may lead to Green being in mate, some (potentially) not to Green being in mate.  In your scenario, Yellow opts for one of his moves that leave Green in mate when his turn comes around.  That is a positive action/choice on the part of Yellow that leads to the mate on Green, which prior to Yellow's move is (generally) undetermined.  Shouldn't the mate be calculated from the point where it becomes his move (and his inabiility to escape check is first manifest)? 

 

Of course, by this logic a one-player mate might be "undone" if it is not a capture of the King, if another player can move in the interim and undo the mate.

In all cases, if a K is captured there is no ambiguity where the points go.
