Capablanca's chess. An enlarged chess variant, proposed by Capablanca. (10x8, Cells: 80) (Recognized!)[All Comments] [Add Comment or Rating]I'm wondering whether anyone has observed that it tends to be difficult for either side to castle fairly early on (if at all) in typical games of (10x8) Capablanca Chess (i.e. final version of this CV).
Quite a while back I invented a new form of castling (originally for use in my 12x8 Wide Chess CV invention). This form of castling became known as Fast Castling - assuming at least some people like this form of castling, maybe an experiment could be tried sometime where (10x8) Capablanca Chess is played with the use of Fast Castling rules (or at least posters could give their thoughts on if the change might be a good idea). The rules for Fast Castling are as follows:
"A king that has never moved, and is not in check, can 'leap' once a game, along the first rank, to any unattacked empty square between it and an unmoved rook, followed by said rook 'leaping' to the king's initial square so as to complete castling in one single move. It does not matter if any squares in between are occupied or under attack."

Hit and Run Chess. After the first move, players may move 1 piece twice or two pieces once, capturing only on any piece's first move.[All Comments] [Add Comment or Rating]If anyone has questions or wants examples, please feel free to ask. I've been playing this since the 80's and if it's something that hasn't come up I'd be interested in looking at it, and if it has come up I am more than willing to explain how it works.
Horseman's Chess. Game where pieces mount and dismount.[All Comments] [Add Comment or Rating]That's an interesting idea. I suppose if the capturing piece is mounted then it would remove the target's mount.
My goal in this game was to decompose the standard chess pieces (kind of like a Fusion Chess in reverse) and remix the bits. Arbitrary combinations turned out to be too powerful, but the mount idea seems to be a good level of modularity.
Did you ever try having a capturing piece take the mount of the piece it captures?
Thank you. The hard part was coming up with an incentive to actually change mounts mid-game.
An early playtester had the brilliant idea to start off the mounts under the pawns. That creates the necessary incentive, and it helps the pawns fulfill their traditional role of being in the way :)

Asymmetric Chess. Chess with alternative units but classical types and mechanics. (8x8, Cells: 64) [All Comments] [Add Comment or Rating]Now I think that Guard (Orcish Pawn) must have promotion to Harpy (Orcish Bishop) only (earlier they can promote to Werewolf also). This is about 2% winrate nerf of Orcs.
Returning Rangers (Elvish Bishops) and Unicorns (Elvish Knights) to their natural starting positions ('c' and 'f' files for Bishops, 'b' and 'g' files for Unicorns) maybe is about 2% winrate nerf of Elves too.
In future, I will check update of race winrates (this will spend several days).
Update rules.
Remove next rule:
- Elvish Knights and Elvish Bishops are exchanged with starting places: Knights stay on the files "c", "f" and Bishops stay on the files "b", "g" (need to defend all Elvish Pawns)
This rule was introduced because of Elf-Elf mirror matchup, having 1. Qc3 move attacking g7 Pawn (and opponent must reply 1.... gf6 or ef6, because if Qe6 then 2. Bc4!).
But this rule has influence to Elf-Human matchup, having 1. Rh4 attacking h7 pawn (and if 1.... g6 or Nf6 then 2. Bd4).
So I think this questionable rule must be cancelled.
Now I start to get new statistics of mathups, with Fairy-Max auto battles:
- at 1000 ELO (0.6 sec per 40 moves)
- at 1400 ELO (6 sec per 40 moves)
- at 1800 ELO (1 min per 40 moves)
- at 2000 ELO (10 min per 40 moves)
How I get these ELO? I have ~95% winrate FIDE chess White vs Black when 1st White engine has 10 times more time than 2nd Black engine.
At low ELO I can get statistics very quick and modify rules to balance sides for it. But at higher ELO I can get statistics much slower, and can just check if balance is OK or not.
~10 000 games must be played for 1% accuracy (~100 games has only 10% accuracy - even equal sides may play 60-40).
I think the only things to be modified must be promotion rules. For example, introducing limitation of Orcish Pawns to promote only minor Pieces, lower Orcish winrate from 58% to 52%. Now I think that Elves and Orcs are a little stronger than orthodox Humans (~+2% winrate) and this point must be fixed.
Also, the most interesting thing is getting Pawns and Pieces values (at different ELOs). By statistics and changing start Pieces I can get only starting values. For example, starting values of orthodox Knight and Bishop are equal.
But there is also mid values which can be used at middle-game exchanges (theoretically, these mid values are best values for Fairy-Max engine, i.e. with these values Fairy-Max must have maximal winrate (vs engines with other values). For example, mid values of orthodox Bishop will be greater than orthodox Knight, because having less Pieces and Pawns at the board than at start.

I still would prefer a knight 2-move diagram that shows that they can move after capture in the same direction. And I think the bulleting structure of the rules section could be made clearer; I may take a stab at that later (and you can use the Revision tool to revert or rearrange things to your liking).
And yes, all of the editing options remain post-approval; the only things that changes is that non-logged-in users can view the page, the banner of alerts is removed, and the page will show up in all index queries.
So, how does this work, I believe I have covered everything that has ever come up since it's inception in the 80's. I can add examples if needed, but will it be open for adding graphics after it gets off probation or not?
Well, I believe I've clarified Capturing en passsant. That's always been a sticking point as I've only ever taught it in person and simply mentioned it in the rules before.
I've just never had the right words for it, but I guess the diagrams help. :)
However, I felt it was a bit vague as well and needed clarifying.
Checkmate is only ever achieved on the defending Kings turn, as it is in Chess. The King always gets a chance to get out of Check. The 50 move rule is as much a thing in Hit and Run Chess as it is in regular Chess.
If your piece moves to put the king in Check, and that move reveals a piece lined up to capture the king, It is still just Check. Sovereign defeat can't be taken, it must be accepted. You can't just swoop in and capture a king.
Check Mate, Stale Mate, mutually agreed upon draw, it's all determined on the Defending Kings turn. However, you can try to pad your Check as much as you like with your pieces. A King that can't escape is always a Checkmate, after all, unless they can't move at all and are not in Check, of course. I believe a stale mate is always in favor of the defender in Standard Chess, at least that's how I was taught.
I did say no King can ever be captured without a Check, but I see that was a vague. I guess I've always just felt the Check/Checkmate rule to be Standard Chess rules, but it makes sense that with two moves it should be clearly stated exactly when Check and Checkmate take place.. I'll add the above clarification to the Rules.
Thanks!
Showdown Chess. No draws permitted. (8x8, Cells: 64) [All Comments] [Add Comment or Rating]H. G. Muller wrote on Sat, Jan 2, 2021 08:33 AM UTC in reply to Benjamin Silversten from 01:17 AM:I don't think the rules as given are viable. Stalemate is defined as a condition where you don't have legal moves, but are not in check. Making a move illegal that cause stalemate thus makes a recursive definition, where it is not clear that the recursion will always terminate.
They also do not address the 50-move problem. What if a game ends in K+R vs K+R? There exists over 10 million positions with this material, so it would be really tedious to force a repeat. But since there is no way to force checkmate, you would eventually be forced to repeat. Which is illegal. But you might not be in check. which makes it a stalemate. Which makes the previous move illegal. But other moves there might (directly or indirectly) suffer from the same problem, so now that position would be a stalemate too. Etc.
I suppose that eventually one of the players would be forced to sacrifice its Rook as the only legal option, but it seems pretty much undeterminable which player that would be. That applies to every position that under normal rules would be a dead draw, e.g. K+B+N vs K+B+N.

I was worried the Queens diagram was a bit busy, but the Queens options are much more complicated , so felt it still helpful. In actual play it doesn't seem so complicated, but I'm also not trying to convey a physical image of good and bad choices. :)
The diagram itself is probably a symptom of me being a programmer...

Hit and Run Chess. After the first move, players may move 1 piece twice or two pieces once, capturing only on any piece's first move.[All Comments] [Add Comment or Rating]Thank you very much, I hadn't even thought about the spelling.
Just a little remark on language: it is 'en passant', not 'en passé'. ('En passé' is grammaticaly wrong in french).
Very interesting, I looked through the known Double Move Variants and I really didn't know there were so few. There are elements of each one that I particularly don't like. One even sounded like an opposite of mine regarding returning to the original square after a capture.
Hit and Run Chess was developed with the premise of trying to keep the game as close to chess as possible, while keeping it balanced and not introducing new pieces with special moves.
The first move in any game can be pivotal. No matter what side you play. Starting out with 2 moves seemed to break the game. Equally, forcing only the first player to forfeit their second move seemed unfair. So both players open their games as they would in standard chess, they both move one piece once.
A straight line capture and advance also proved to be game breaking. Way O.P. and resulted in much faster and less interesting games. The concept of Hit and run was basically born, although not realized, by the introduction of the divergent path after capture. It seemed unfair that this affected all pieces except the knight. However, the night had one annoying predilection, that of striking out from behind the safety of the Pawn wall and retreating back to safety after capturing. So to even things out and to challenge both the player and his Knight, the Knight was restricted from doing this, Ostensibly applied under the divergent path rule, as for all pieces, their Starting square was along their path of attack and it seemed bth balancing and fair.
Capturing on the second move was also way over powered, as it could conceivably result in a Check Mate without Check, which is why I suppose, other variants impose the end of turn if a check is made on the first move. However, who wants to lose their second move, really. So to further drive home the idea of Hit and Run Chess, and the thing that truly gave it life, was to limit all captures to only the first move of any piece. Thus also allowing the wonderful feeling of being able to capture two pieces in the same turn when moving two pieces once, while making the second move of any piece that captured on it's first move. a maneuvering move.
As balanced and fair as possible, uncomplicated due to retaining all of the regular rules as far as how the pieces themselves move. Should be easy to remember as there are only a few stipulation.
Move one piece twice, two pieces once, Capture only on the first move of any piece, and taking a divergent path if moving one piece after capturing.
Well, I guess you might not be interested as to why the game has evolved to what it is, but I found it interesting how these other variants approached the same issues.
I'm definitely biased ... :)
Bn Em wrote on Fri, Jan 1, 2021 08:54 PM UTC:Any movement (aside from the null move if you count that) has a direction; in the knight's case, as with oblique leapers in general, it happens to be between the usual ortho‐ and diagonals, but it's still a direction just as a dabbaba's or alfil's (2‐square leap ortho‐ resp. diagonally) leap. Hence also the nightrider, which makes multiple knight leaps in the same direction (e.g. from a1 to b3,c5,d7 or c2,e3,g4 on 8×8), and with which many readers will be familiar, hence the confusion over the knight's ‘path’.
Fwiw the queen diagram is cool, if a bit daunting‐looking at first
Thank you, I don't know if this will be an issue, but I added one more image to illustrate an OVER examination of the Queens options with a Hit and Run move. As you can imagine Queens have many more options.
I hope it does not cause issues. If it is, I can re-upload it later. if images can be added to the Variants after they have been released, or will that be a final form?
I'm not sure I understand what you mean by "... the knight diagram would be better if the second move in the same direction was on-board." Knights don't, technically, have a direction, they jump. The only real restriction for the Knight is that it can't return to it's original square after capturing.
I didn't want to clutter the image up with a bunch of L shaped arrows. (Unlike the Queens examination, which is a bit busy, but hopefully understandable, with Captures referenced by the red X along with the Restricted Movement After Capture Arrows, rather than the long green arrow, which was ok on the diagrams with fewer options, but was just too much for the Queens Diagram.)
Again, I really appreciate your help.

Hit and Run Chess. After the first move, players may move 1 piece twice or two pieces once, capturing only on any piece's first move.[All Comments] [Add Comment or Rating]Technically, the restrictions only apply after a capture and only if you choose to move the same piece for the second move. Sort of a checks and balances type of thing.
Knights are kind of special to begin with. They don't really have "lines" or "paths", rather they have landing sites. Without a capture the Knight may go anywhere it can legally reach on it's second move that is not blocked by friendly or unfriendly pieces. So (assuming all potential landing squares are clear) a knight has all 8 squares free to move to after it's first move, and if it captures on it's first move then it has 7 places it can go since it can't return to the square it attacked from.
The restrictions on movement after capturing helps to balance the game and imparts an element of danger when you can't just strike out from a safe position and then simply return to safety every time. The reason for limiting the attack to the first move also helps maintain balance. If you are allowed to capture on the second move a checkmate condition is more likely too early in the game and really doesn't make the game any more fun.
However, if you are simply going to move one piece twice for the sake of positioning, then the board is your playground. If you want to sandbag your two moves by moving and returning to your original place, so be it, you just can't do that after a capture.
The ability to make two captures in one move is still there, so long as you use your two moves with two pieces moving once each.
Keep in mind that you can't really cover another piece very reliably, as you can in standard chess, because someone can swoop in and capture it, then run away.
As for the names, it was originally dubbed RuneChess, but that was simply because I ran a BBS by the name of RuneStone. Hit and Run Chess is the name that best describes the game.

In the elseif clause whose code should have run, I replaced references to $userid with references to $_SESSION["userid"].

So, try accepting the invitation again.

I think this page would benefit from some discussion on the reasoning behind the restrictions, especially as compared to other double-move variants (I've added the tag double-move to as many as I could find). I'm also unclear why the variant has three different names, only the first of which seems at all related to the game's mechanics (but I think suggests somewhat the opposite of the same-line restrictions...).

Hit and Run Chess. After the first move, players may move 1 piece twice or two pieces once, capturing only on any piece's first move.[All Comments] [Add Comment or Rating]Sorry, for some reason my response was just blank when I previewed. If a Rook moves from E3 to G3 to capture, and the player wishes to move the same piece after the capture it may not continue along the same row to H3 or return towards A3, but must instead follow G either toward G1 or towards G8. Same goes for Bishops, but they may only move along the opposite diagonal from the diagonal moved along to make the capture. Knights cannot return to the square they moved from to capture, but may go to any other square it can reach, so long as the square is unoccupied, since no piece may capture on it's second move. Queens may follow any other path than the one they used to capture. In order to move, they have to diverge from the path they took to capture. If they cannot go another way the piece cannot take a second move.If no other piece can move, the second move is forfeit that turn.

I think we are a bit attracted by the same concepts. Very Heavy Chess is maybe really too much and at the end boring. First tries I made with ZoG didn't show that but time will tell. Using compounds of FIDE pieces is also a direction I had in mind for my family of CV beyond Metamachy and Zanzibar.

I suppose using a list of royal types similar to pomoChoice would be a better way to do it; currently you would have to specify a number of royal= parameters if you want to have multiple royal types. (But it is of course very unusual that you would.) Perhaps I should add a parameter royalTypes that works that way, which is then interpreted only after all pieces have been defined, and deprecate the royal parameter.

It's basically just chess with Pawns as the extinction type. And pawns promote only to kings. So I thought this would be simple, but it doesn't seem to detect endgame and the AI does not move at all. The code is below (but it's also on the page so you can try it):

Published. I made a variety of small changes, which you can see if you compare my revision with your last one. Most notably, I changed the Latin word summum to the English word summit after looking up its meaning.

G. Muller wrote on Tue, Dec 22, 2020 06:38 PM UTC in reply to Greg Strong from 05:16 PM:I suppose I should drop the requirement that the piece that castles must be royal. As at the moment the Applet generates the code the Diagram in it still thinks the royal piece is the King. I don't think there is any downside to that: if one specifies a piece can castle, that piece will obviously need partners, and the Diagram should figure out how wide the board is at that point. Even if the piece is non-royal.
Greg Strong wrote on Tue, Dec 22, 2020 05:16 PM UTC in reply to H. G. Muller from 04:30 PM:Thanks! I'll read through the tutorial again.
I was able to make a Knightmate preset, although I did have one other issue. I set the king's move to K and the knight's move to NisO2 but castling still did not work. The issue was that the set partners line was not generated. So there may be a but where the partners variable isn't set if the castling piece isn't the king.
H. G. Muller wrote on Tue, Dec 22, 2020 04:30 PM UTC in reply to Greg Strong from 04:01 PM:No, the Applet always considers the King royal, and keeps the order as it is in the selection table (so that Pawns will lead the list). This is just because I tried to keep the interface as simple as possible, and an overwhelming majority of all variants would need it this way.
When making a Diagram it is easy enough to edit the generated HTML definition for swapping the order of the piece lines, or altering the royal parameter value. In the generated GAME code such post-editing is also the easiest solution to the rare cases where you would want it differently. I described this in the Game-code-generation tutorial ('Multiple royals' section). You just have to put your own assignments to the (array) variables wroyal and broyal, to overrule the default setting the include file gives them:
set wroyal (N); // royal pieces set broyal (n);

Can it make a GC preset for Knightmate? I don't see an option to set the royal parameter. If I place knights and move them around to capture the kings do the knights then become the last in the in the list?
H. G. Muller wrote on Tue, Dec 22, 2020 10:59 AM UTC in reply to Greg Strong from Mon Dec 21 11:21 PM:The problem was that you defined the Knight first. The order of pieces is important in two ways:
- if maxPromote=N (default 1) the first N pieces will be promotable
- if you don't explicitly assign royalty through a royal=N parameter, the piece defined last is the royal
I guess something went wrong in the attempt to promote the Knight when it left the 1st rank. This in combination with the fact that you defined invalid promoChoice (namely lower case, while the defined piece IDs were all upper case).
Lions and Unicorns Chess. With the 16 standard pieces and 4 powerful leapers. (10x8, Cells: 80) [All Comments] [Add Comment or Rating]You mention that Jetan has long fascinated you. But I see few parallels between this game and Jetan. Can you please explain the connection and/or inspiration?

Reading the rules makes me want to play it; and also to design something similar, but it seems impossible to make anything quite as elegant as this.

It's refreshing to see more comments from different people (some being newcomers?) on various CVs etc. on this site, even if some don't plan on playing, or authoring/inventing, things anytime [soon].
