The rules rewritten are accurate. Thanks.


Fergus Duniho wrote on 2017-09-29 UTC

I was meaning to rewrite the rules to make them clearer. I'll do that here, and you can let me know if these are still accurate.

Apart from differences in the setup, already described above, Captive Kings Chess is played like Chess with these further differences:

1. The object is to move your King to your side of the board. This is accomplished by moving White's King to the fourth rank or Black's King to the fifth.

2. A King may not move to a space on which it would be in check by the rules of Chess, but it may remain on a space on which it would be in check, since there is no real check in this game, and no piece may actually capture the King.

3. Capture is not allowed on a player's first move.

4. The King is not allowed to capture any pieces on the opponent's first rank, this being where each King starts, but it may capture unprotected pieces on other ranks, including Pawns on the second.

This covers what you listed as 2-5. Your #1 is already covered in the setup section, and your #6 does not appear to be a rule. It seems to be an observation that follows from the other rules, not an additional rule of the game. This could be mentioned in another section, such as introduction or notes, but when something is not an actual rule, it can be confusing to list it as one.

Is there any flaw in the variant or must I modify any rule?


Joel wrote on 2017-09-15 UTC

<However, the exceptions are as follows which are explained from White's point of view.

2. The objective is to bring the imprisoned white king to the fourth rank. (Black king to the fifth). The first player to do so wins the game.>


Joel wrote on 2017-09-15 UTC

Yes. I meant to say that the since the white king is placed on the eighth rank (in the Black's territory), it must reach the fourth rank (White's own territory, any square between a4 to to h4). Similarly, black king must reach the fifth rank (Black's territory, anywhere between a5 to h5) from the first rank. The player who first reaches his king to the target squares wins the game.

In my sample game, the game ended in Black's favour because it reached it's own territory by making up to the fifth rank (h5) while the white king was a move away to reach it's destinated square.


Fergus Duniho wrote on 2017-09-14 UTC

Looking at your game, the white King moved up to the fifth rank on its last move, never making it to the fourth rank, and the black King made it only to the fourth rank. But the rules say that the white King must make it to the fourth rank, or the black King must make it to the fifth rank. Since neither of these happened, it doesn't look like this game completed.

Thank you and sorry for the trouble. It's because I'm totally new to these coading of boards and pieces that I really had a hard time to do things correctly.


Fergus Duniho wrote on 2017-09-14 UTC

I corrected what you posted to be actual HTML. The first thing I noticed from your game was that the Kings started on their opposite sides. And I now see that in the diagram, which maybe you didn't have earlier, since I don't remember seeing it before, and it would have helped a lot.


Joel wrote on 2017-09-14 UTC

Thank you Mr. Reinhart.


V. Reinhart wrote on 2017-09-14 UTC

Thanks Joel for clarifying the sample game. I just wanted to make sure I understood the game. It's an intersting variant!  Good work.:)

Whatever you do, please never do that. Stepping through a game with Game Courier borders on the unbearable. Even if you set the view from the First Player perspective, every next position you want to display causes the load of a new page, with a waiting time during which the screen blanks out, while afterwards the board and the button you are clicking appears in a different place, because the size of the ad in the header will have changed. This combination of prolonged flashing and the image jumping up and down makes any continuity with the previous position as good as impossible.

This place has become very difficult to access lately anyway; sometimes I have to wait up to a minute with a blank window before something gets displayed, after a page refresh. In the status bar of the browser I can see that it is then waiting for data from websites like ebay and such, probably for fetching ads.

I hope I've posted the game like you told me to. I'm not sure though.

Game :












 


Joel wrote on 2017-09-14 UTC

You are right. Playing maybe 1.e3 followed by Qf3 would've been more logical. I only wanted to demonstrate a short game for the readers in order to get a quick idea.


V. Reinhart wrote on 2017-09-14 UTC

If the idea is to keep the opponent king trapped, and to rescue your own king, why did both White and Black let the opponent kings escape on the first move?

Wouldn't it make more sense to keep your opponent's king trapped for as long as possible?

I couldn't post the demonstration in Chrome for some reason, but Waterfox (which is a 64-bit version of Firefox) let me post it.


Fergus Duniho wrote on 2017-09-14 UTC
Let's try this with Waterfox. This should be the demonstration.


Fergus Duniho wrote on 2017-09-14 UTC

I'm going to post a demonstration shortly, but I have to fix something first.


Fergus Duniho wrote on 2017-09-14 UTC

Here's what could be more helpful than posting a game in abbreviated algebraic notation. Go to play.chessvariants.com/pbm/play.php, click on Move, play out a game that demonstrates how this game works, then click on Annotate, add appropriate annotations (which is explained below), then click Get Code, copy the code to the clipboard, come to this page, start to write a comment, click Source to enter HTML code, then paste the code into your message. This will allow us to use Game Courier to view the game move by move, and it will be less likely to include mistakes than something you do by hand. To enter annotations, enter them like C++ or PHP inline comments, which normally begin with // and occur either at the end of a line or on their own line. A comment on its own line will be displayed with the preceding move. So, any annotations for a move should occur after the move, not before it.


Fergus Duniho wrote on 2017-09-14 UTC

You're right. On the second move, the white King is going to the 7th rank, and the black King is going to the 2nd rank.

Huh?  This game score makes no sense.

21. Kd5 Kh5

0-1

I'm not clear on how this game is supposed to work. The rules do not clearly tell me how to play it.
