well just like in normal chess you don't actually capture the kings (either of them) :D
But in normal Chess there are rules that forbid you to leave your King in a capturable position. So no extra rules are needed, because the situation simply cannot arise.
With the rules you propose above, however, you can end up in 'pseudo check' after your turn. Which means the opponent can then capture one of your Kings.
Even when you end your turn with none of your Kings attacked, ('null check'), the opponent could discover a check on one of them with his first move, and then capture that King with the second move.

But this isn't normal chess, the rules are different:D

Both true,it looks like I need another rule:
"you don't capture the King(s) even though you CAN (in the sense that you have moves that can capture the Kings)"
I didn't put this in the rules origanlly because it didn't occur to me to do so i.e. I didn't think it was important to make this clear! sorry about that and thanks for pointing that out.:D
when I said it was "comparable" to the rules of normal chess, this is what I meant:
First let me just create someterms
If you were in "Null Check" or "Pseudo Check" you call that "One Check"
If you were in "True Check" you call that "Two Check"
in Normal chess you are either "in Check" (King is threatened) or "Not in Check" (King isn't threatened)
Now here's the comparison: Normal Chess/Double Chess
if you make a move you must be in "Not in Check(King isn't threatened)"/"One Check"("Null Check" or "Pseudo Check") situation
if you are in "Check"(King is threatened)/"Two Check"("True Check") you have to escape it if you can, if you can't then in BOTH cases it's Checkmate
If you are in "Not in Check(King isn't threatened)"/"One Check"("Null Check" or "Pseudo Check") you must make a move that maintains this (as explained above:D (and if you can't make TWO moves in this situation then it's stalemate)
I knew when i first posted this thread there was going to be some questions that would need to be answered so I hope I've answered your question properly now
I invented a chess variant called "Double Chess" (I have no idea if a similar variant exists)
Rules:
the following rules are no different than normal chess (I put notes to indicate "possible differences")
- the way pieces move
- en passant (though the pawn are on two ranks, the rule applies to both ranks)
- castling (though I haven't finalised the starting position yet)
- promotion
rules which are different
moves: a "turn" is composed of two moves, which must be made by two different pieces (there are no exceptions)
pieces used:
King 2
Queen 2
Knight 4
Rook 4
Bishop 4
Pawn 17
(the number refer to the quantity of each piece)
Check, Checkmate and Stalemate:
these rules are complex but I think they can be summarised in the following way:
Definitions: "Null Check" if neither of a player's Kings is being threatened
"Psudo Check" means that a player can "create" null check in one move (not turn)
after a turn (two moves) the player must be in either "null check" or "psudo check"
if at least two moves (not turns) are required to obtain "Null Check" that's called "true check" (or just "Check") i.e. one move is insufficent
if a player is in "true check" and can't create either "null check" or "psudo check" by moving two different pieces then it's checkmate
If a player is not in "true check" and they can't create "Null check" or "psudo check" then it's stalemate (I haven't figured if this is possible yet)
btw it is comparabel with Check, Checkmate and Stalemate from normal chess:D
hopefull that summarises it if not you can ask me questions about it:D
the game is played on an 11x11 board with the 33 pieces occupying the first 3 rows
I think I have got an arrangement I just need to see if it is suitable or needs to be improved
I think the best way for me to test this game is through making puzzles (which I will be posting shortly, btw i Haven't actaully made any yet:D)
EDIT: when a pawn promotes it is still classed as the same piece so if you promote a pawn on the first move you can't move it away on the second move.
