Capture The Flag Chess

HorribleTomato

I'm sorry if this has been invented before, but this type of chess is called "capture the flag". @Vickalin or @Martin0 can you help me develop this variant? You don't have to.

An interesting variant. This game adds secret information, so changes it from a game of perfect information, where both players can see everything to a game where the players hold a secret.

Rooks often last a long time in chess, so it makes me wonder if placing a flag with a rook is a good plan. But your opponent knows about that too, so maybe you can trick him out by giving the flag to a knight (or even a pawn). The game could have some surprise endings!

Not sure what your display looks like, but this chess graphic has some problems on my PC (see this):

The pieces are clipped. But this is not related to the game - it's a cool game idea.

@Evert823 gave me this idea with his team/flag/four player/game You have to get in the other player's head, especially in the switching flag holder variation. Giving the queen the flag is kind of obvious i.e. avoiding Q trades and treading carefully about Q placement... then again, this can happen to any piece.

I think I saw a streamer, Can't remember who made his own version of this? He said 'Garry' the G pawn was the master and if he gets captured he automatically resigns. His opponent did not know this of course

So, one piece is the flag? How would the opponent know if the flag wasn’t being changed?
Pawnlings

That's why he said you'd have to tell the Moderator or a third party

Pawnlings

Could write it down as well

since bulldog/infinite chess usually has a monitor, I figured this wouldn't be a problem

Incidentally I have an event in event chess that is named capture the flag. That one is completely different though, since in that variant any piece that reaches the opponents back rank gets a flag and if that piece manages to return to the first rank, that player wins.

 

I have played a few variants with hidden information and I have to say I think it works pretty well. This variant does sound like it can potentially be pretty fun. I would probably add some rules to make the piece with the flag a bit more exposed. Like the piece with the flag is unable to capture pieces and is unable to move over a checked square (they would have to stop at the checked square). Of course pieces that can jump would ignore that rule.

 

I also think you need to have it a bit more defined how passing the flag works. Does it cost a move to pass the flag? If not can you pass the flag before or after you have made a move (or both)? Are you able to pass the flag several times during the same turn? etc.

HorribleTomato

Thanks. Let's make it cost 1 turn, 1 time per turn. I also like the no capture and checked square one is good. Thanks for all the ideas!

Sounds like an awesome idea!

hitthepin
I agree.
HorribleTomato

the only problem are draws. Do you think the game will be drawish and should we add more rules preventing draws (normally in the endgame) 

HorribleTomato

The best thing is normal version can be played on a regular diagram!

chadnilsen

I think it should be played like regular chess, (with check and checkmate) but capturing the flag piece is just another way to win. And it should be against the rules to give the flag to the king or queen. The queen would pretty easily keep safe.

HorribleTomato

:/ nah. Good idea, but the concept of the flag holder is it acts as a secret king. Of course, the queen should be able to hold the flag, and with the check shield (see #12) and it would be quite obvious, so putting the flag on the queen restricts your best piece

chadnilsen

Oh I didn’t read that.

chadnilsen

It would be easy to play this on a real chess board, because you wouldn’t need a third person to keep track of the flags. You could just write down the piece at the start and every time you change the flag piece.

chadnilsen

Switching the flag holder should be changed so that it's not so easy to just keep switching to whatever piece is safest at the moment. Here's my idea:

hitthepin
Would the king be subject to check/checkmate? Or would it just be another piece?
