Fergus,

I was thinking...

In the interest of natural evolution, do you think I should contact the inventors of said 3 variants, because I owe a great deal of inspiration from them and ask If I can publish my variants as fully fleged ones, so when it comes to that website that you were talking about, the variations on the otherwise very good variants would stand a chance on they're own. What I have actually done is take two good variants and combine what I considered their strengths into 2 new better, in my view, variations.


Aurelian Florea wrote on Tue, Sep 13, 2016 04:15 AM UTC:

Fergus,

I am concern about the quality of the games, that is why I asked for advice from knoledgeble people. So any comments on the actual games? Or anyone else for that matter. Comments on the quality of my games are highly apreciated, as I am rather new.


Aurelian Florea wrote on Tue, Sep 13, 2016 04:22 AM UTC:

Kevin,

We live in the age of the internet, so playing online overcomes many of the problems related to not having enough material. I never played chess professionally but if i had the resources (I don't) I'd gladly organize chess variants events.


Aurelian Florea wrote on Tue, Sep 13, 2016 05:26 AM UTC:

I think I was not clear on a matter of outmost importance. The point of this small discussion I launched was to find objectively good variants to play, for that contributions to the same game by many variantists are welcomed, so tell me: Aurelian you did that good, that wrong., H.G. started it a little bit. I'm going to do a little self criticism too. A treaper (3,3) enhancement to the knight (the fact that is just move has no bearing here) could be a little be to long to be effective (espeacially in the opening) on a 10x10 board.


Aurelian Florea wrote on Tue, Sep 13, 2016 08:32 AM UTC:

I've managed to put in more beautiful diagrams. So what do the letters mean:

For the top diagram: R=Rook;W=Wizard;C=Champion;A=Aanca;G=Griffin;N=kNight (has also a zebra just move);B=Bishop;Q=Queen;P=Pawn

For the bottom diagram: R=Rook;Z=Zebra (has also a ferz just move);L=cameL (has also a wazir just move);E=modern Elephant(ferz+alfil+treaper just move);A=Archbishop;M=Marshall;N=kNight (has also a threeleaper just move);B=Bishop;Q=Queen;P=Pawn

In both games each player starts with a foul in hand. A foul may be placed during a move on a place vacated by a non-pawn piece moved for the first time. A foul imitates the last move of the opponent. A foul my imobilize kingwise adjacted pieces.

What do you guys think about these games, are they better that the originals? Are they good enough to be published?


Aurelian Florea wrote on Tue, Sep 13, 2016 08:34 AM UTC:

H.G. I think you are sadly correct, but this doesn't stop my passion for inventing better games if possible!


Aurelian Florea wrote on Tue, Sep 13, 2016 08:38 AM UTC:

Regarding my second to last comment I also changed some of the rules of the game!


Aurelian Florea wrote on Tue, Sep 13, 2016 09:38 AM UTC:

Thanks H.G.


Aurelian Florea wrote on Tue, Sep 13, 2016 09:42 AM UTC:

I think I have to do a bit of work with pieces like aanca, and maybe scrape the foul totally as it's difficult to implement- I am refering more to the freezing ability.


Aurelian Florea wrote on Tue, Sep 13, 2016 09:58 AM UTC:

I guess I have to learn Betza's funny notation, which is not hard but i don't remember for example how to write a moving and capturing camel+moving ferz. Thanks for the food for thought H.G.


Aurelian Florea wrote on Tue, Sep 13, 2016 10:35 AM UTC:

How do I write the AAnca in betza's funny notation?


Aurelian Florea wrote on Tue, Sep 13, 2016 10:47 AM UTC:

and I want my aanca to be able to stop after the wazir move!


Aurelian Florea wrote on Tue, Sep 13, 2016 10:52 AM UTC:

Thanks HG, I had already found the funny notation materials!

Aurelian Florea wrote on Tue, Sep 13, 2016 11:10 AM UTC:

1. Is it possible to add and foul, a piece that imitates the last move of the opponent?

2. I'd like on a 10x10 board to make the promotion zone from rank 8 to rank 10 for pawns. Pawns should promote to maximum rooks at ranks 8 and 9 and everything on rank 10. Can I do that?

Thanks, for this wonderful tool you just uncovered for me!

What do I do with the result, as I'd like to experiment with playing the game a little bit before submiting it. Earlier I've deleted a pawn and I had to do it all over again. I do not want to repeat that. Now that I tried it a bit it doesn't seem worthy for publishing IMO.

Aurelian Florea wrote on Tue, Sep 13, 2016 03:31 PM UTC:

Fergus,

I agree with what you said, I'll still try them just for fun, but it's hard to come by a worthy successor.

I meant fool, yes, please pardon my English spelling.

Also all the 3 long jumps are a bit awkward on 10x10. I think they'll work fine on 12x12, but a 12x12 board raises new problems.

Thank you for minding my ideas! It is appreciated.

I'll try the games using HG's diagrams, but I don't think I'll publish them as variants, as spamming variants is not useful. Something I studied and could prove useful is my ability to do machine learning programs, maybe I can come up with clever AI for some variants, and compete with HG and Greg, I don't claim their experience but who was born knowledgeable.

Besides that I have some idea of new variants, so I know that I'm always welcomed here.

P.S.  I haven't forgot to use the spell checker now :).

Ok, thanks! I actually know nothing about JS but i'm good with general programming so I guess i'll handle myself!

In the meantime, I think I inadvertently posted 2 variants I did not suppose to, How do I delete them?


Aurelian Florea wrote on Tue, Sep 13, 2016 04:51 PM UTC:

Ok, I have no clue how to do what you've just said on my computer, if you have the time to tell me the baby steps, or let me send you the html code that the wizard has done, make work on your machine and then send me the result i'll owe you a beer, in my first trip to US, or your first trip to Romania

Aurelian Florea wrote on Tue, Sep 13, 2016 05:32 PM UTC:

Well, we teach children more and more complicated things, and we have more and more complicated machines to teach us the grand master level. So a 10x10 variant with 24 pieces is really no effort. That is not to be said for increasingly large variants. The point of this discussion was that some games exist and they should look at each other in order to better themselves.

My introduction of the griffin and aanca was somewhat arbitrary, they were the first pieces that came to mind when asking myself about non-queen major rider pieces so I wouldn't repeat the archbishop and Marshall in the other variant. The griffin and aanca are, yes difficult to use pieces.

I think orthodox chess should be always for kids but larger board variants should enter the repertoire of adults.

My main fear is that chess playing actually is a  craft for the machines and for humans we should keep hold off games like Dixit for example. That's not an issue, just something we should be aware of.

To put it in perspective why the dichotomy between homo sapiens and machines. I have a permanent debate with a friend of mine about human intelligence vs machine intelligence. Him, a Dune fan, thinks we should train ourselves like the mentats in order to better ourselves. I think we should base ourselves on robots, eventually, when tech allows it become such beings.

This dichotomy is the seed of my 2 objectives I stated in the beginning of this discussion :

1. What is the next evolution of chess

2. How computer chess should evolve

On the less discussed second matter I think chess variants engines should provide software companies what FORMULA1 GP provides automotive companies. I think variants solving the two matters will be very different, especially in size, but also the aanca or  the zebra can't seem awkward to a machine, it's just a move.

On the matter of contributing to a variant that could be part, among others at the next evolution of chess, today I failed, but all hope is not lost. With all risk involved I'll head towards larger board size, for already grandmaster adults and not kids.

Thanks for your time!

That's actually a good idea, Totally displacing chess was never the main purpose as is a very good game. I have newver programmed for mobile but it shouldn't be so hard. An aplication for children is wonderful. But I'm also thinking at something granmaster level, wtih a very strong AI that gives increasingly lower handicaps until impossible levels maybe, where the computer recieves a handicap from the player. That shouldn't block the player though!


Aurelian Florea wrote on Wed, Sep 14, 2016 02:23 AM UTC:

Or on second thinking, why not an aplication for children that reaches grandmaster level at high levels of play!


Aurelian Florea wrote on Wed, Sep 14, 2016 03:20 AM UTC:

I've made some experiments with those two games. It's actually quite exciting but I blunder pieces way to often! After I get some experience I hope to be able to provide a game of each! For now if you would like to try it yourself here are the scripts:

Aurelian Florea wrote on Wed, Sep 14, 2016 04:30 AM UTC:

I personally don't like multiplayer variants as I consider most of them unfair from the point of view that multiple players may attack the same victim. So if that's up to me I won't consider those. Playing against humans of the same level or close it's a good idea but it assumes a large enough number of players, not the case at least initially.

Regarding authority for the game, well the programmers are the main authority, who else. We or they (I'm not sure yet if I will get involved as I am more for more challenging tasks from an intellectual point of view) would consult the community of course.

Time should be enough maybe at blitz or a bit longer, not too fast as the player is not used to playing most of the variants, but not too tedious either.


Aurelian Florea wrote on Wed, Sep 14, 2016 05:05 AM UTC:

I was concerned about the opening in the second game as I put the queen and marshall far from the center of the board. That happened mostly because I was not use to with an archbishop in the middle, but after a few trials it seems fine. I have seen the archbishop in the middle in Paulovich's variant of Capablanca chess, so I guess I am not the only one with this problem. I have done this in order to have the minor pieces (the ones who acording to opening principles attack first) closer to the middle. Although bishops could be 1 square more lateral.


Aurelian Florea wrote on Wed, Sep 14, 2016 10:46 AM UTC:

I tinkered those 2 games a little bit and I came up with the following value of pieces based on their values in Omega Chess (omega chess website), Grand Chess (H.G.Muller values from wikipedia), Ralph Betza's evaluation of the aanca and griffin, mobility calculation for zebra, and my own observations playing the games, I also named the two games so I think I'm ready to maybe submit them, eventually:

Apothecary chess1

rook                   6

wizard               3.8

champion            4

knight                 4

bishop                4

queen                12

aanca                 7

griffin                8.75

 

Apothecary chess2

zebra                  3

camel               3.2

elephant            3.7

knight                3.4

bishop                4

queen                12

archbishop         10

marshall            11

 

I decided to name the games apothecary chess as they are obtained adding somewhat arbitrary mutations to well known games in the way apothecaries used to tinker their receipts.


Aurelian Florea wrote on Wed, Sep 14, 2016 12:09 PM UTC:

Actually my mobility program gives the griffin roughly equal to a queen a little bit weaker on crowded boards but even stronger in the endgame. The Aanca is the strongest among the 3 in the beginning but quickly loses power becoming 21.5/26 queens in the endgame. Clearly stronger than stated. I think the conondrum comes from the fact that mister betza calculations are based on rook and bishop. So the result is that the rook and the bishop are stronger. The bishop is still 4 (ok maybe 4 and something) because it gets a colourboundness penalty, but the rook must be higher. My mobility program give 0.63 queens for the rook.

That beeing said 4 pawns are definetly better than a bishop in the endgame. Remember the rule that they can even promote to a rook on rank 8, but I never got that far with my calculations.

So new values:

rook                  7.25

wizard               3.8

champion            4

knight                 4

bishop               4.2

queen                12

aanca                 9

griffin                 11

 

Apothecary chess2

zebra                  3

camel               3.2

elephant            3.7

knight                3.4

bishop               4.2

queen                12

archbishop         10

marshall            11

rook                  7.25


Aurelian Florea wrote on Wed, Sep 14, 2016 12:12 PM UTC:

The html code posted earlier doesn't enforce the rule that the pawn can promote to almost a rook on ranks 8 and 9 so you must decline manually not to promote to an aanca, griffin, queen , archbishop, marshall.


Aurelian Florea wrote on Wed, Sep 14, 2016 12:14 PM UTC:

the archbishop is a bit high too maybe!


Aurelian Florea wrote on Wed, Sep 14, 2016 12:24 PM UTC:

Actually I don't see many variants with aancas, griffins, or zebras. I assume there is good reason for that. That's why I considered the name paranoid chess, too, but my father advised me against it!


Aurelian Florea wrote on Wed, Sep 14, 2016 12:46 PM UTC:

Aurelian Florea wrote on Wed, Sep 14, 2016 01:03 PM UTC:

I had to change the order in promochoice, but the function works fine provided the piece list is open, or so I think, but that's not an issue

I think both the tournaments, and the video game ideas are good, should we start a post on each of those?

H.G.,

About the pawn, this pawn is slightly weaker than in capablanca as it takes slightly longer to promote, not a big deal, if it's a passed pawn will eventually queen. But there is also a strengthening effect as it can promote at rank 8 to rook (well to a plethora of pieces but the best choice is usually rook). I have no clue how to evaluate this effect but it shouldn't be much as early under promotions will not happen often, I raise that matter because it's specific to those two games.

On the matter of archbishop+pawn there is no reason to doubt you, but I honestly don't know how to normalize everything. There is also no reason to think queens have different strengths between to two games for example. and what about the situation (admittedly rare) R+3P VS archbishop, point being is hard to find a balance.

I'd be honored if you take your time and put forward some values of your own, or on the other hand put some values at first glance.

I think in these cases machine learning could tune very well values, I've read an article somewhere on atomic chess and other games but I can't find it now.

And it doesn't have to be a 1dimesional value an archbishop could worth 10.5 in an A+P vs Q ending and 9.5 in a R+3P vs A ending. I don't know.

You were correct on yesterday assessment that the game is tedious. It takes a lot of time to reach endgame, actually in all cases I ended games through small blunders of pieces in early or late middle game. It became obvious IMO who'll win. :) At least it's not Taikyoku shogi I doubt anyone started that one, finishing it is out of question I guess.

Fergus,

How many points would players get, or at least a victory in Gross chess should worth more that a victory in Omega chess as a tiebreak, in order to also increase stakes as the tournament passes.

"So there now is a corrected file at http://www.membergraphics/MSinteractive-diagrams/betza.gif ."

It doesn't work from here. When I paste this link in my broser it says: Server not found.

HG,

Now it works well!


Aurelian Florea wrote on Thu, Sep 15, 2016 09:20 AM UTC:

I've reached a conundrum. I am far from being a chess grand master, I blunder way to often usually full pieces, the last time I missed a pin, silly me. I can't test the game further into endgame because of that. At my level the game becomes played quite soon, as chances for blunders are increased. On the other hand it was supposed to be an enhancement to the play at high levels. Do you see the conundrum?


Aurelian Florea wrote on Thu, Sep 15, 2016 10:01 AM UTC:

Thanks, H.G. As always helpful!

I was playing against myself, after you blunder a piece you can't go back, and I don't remember the whole game after 25 moves (actually less). Also I did not kept records. I think though it is a good idea now that I advanced a little bit to keep records as some games could prove interesting.

Thanks, for all the help!


Aurelian Florea wrote on Thu, Sep 15, 2016 11:11 AM UTC:

I think there is a way with sjaak to implement my way of promotion. Just create 2 different promotion zones, allow promotion to pawn when the case and that's it. Not tried it yet.


Aurelian Florea wrote on Thu, Sep 15, 2016 11:34 AM UTC:

One think I haven't confessed yet is that I partially like the idea of chess960. Having different starting position is interesting. But not ANY different position. I think in many games you can fine tune 2 to n different setups. And then choose among them. I'm not the first who thought at this I'm sure.

How this does affect this post. I'd like apothecary 1 and apothecary 2 to have 2 possible initial positions. The first one is the one already presented named from now until the hereafter the bishops in or knights out position. The second one name from now until the hereafter the bishops out or knights in has the bishops and knights (each variant with it's own knights) switched.

With sjaak I can just plug two variants with the 2 starting setups, but with the diagram from the presumed variant page it's more complicated, I assume a button switching between the two positions will be involved.

It's that hard to do H.G.? Can you help me with that , too?


Aurelian Florea wrote on Thu, Sep 15, 2016 12:04 PM UTC:

H.G.,

I have not managed to define the Aanca and the Griffin in Sjaak. Have you any idea?


Aurelian Florea wrote on Thu, Sep 15, 2016 12:20 PM UTC:

On the last matter I think the Aanca may be Leap(1,0)+Slide(d,a), but I have to check, the griffin is somewhat similar. The trouble with the griffin is that you have to ban 4 steps (the ones like an wazir).


Aurelian Florea wrote on Thu, Sep 15, 2016 01:17 PM UTC:

well, for an Aanca I can use the property of sliders that their move is a union of many lame leaper moves. But you should see that formula, and moreover, I don't think that is recomended programming wise. I still haven't give up.


Aurelian Florea wrote on Thu, Sep 15, 2016 01:31 PM UTC:

That doesn't work either!


Aurelian Florea wrote on Thu, Sep 15, 2016 01:32 PM UTC:

what if I convinct myself to FairyMAx for both games, just for symetry, I think I can handle weird scripts!

I wonders how inteligence relates with larger board variants. I think there is an saturation meaning that after a certain IQ, IQ surplus doesn't show anymore for classcal chess. In variants the more complex the game the more that saturation coeficient is increased.

H.G., I think I'm all lost!

I can't figure how to set up the proper initial position. As a matter a fact I'm not sure I understand much from what you send me earlier(the text for the .ini  file i mean) besides the board on some piece movements. But you have put an example with all the pieces, so that's fine. I'll manage with that.


Aurelian Florea wrote on Thu, Sep 15, 2016 03:57 PM UTC:

It gave an error, forfeit due to invalid move, I guess white wanted to promote at 8 rank!


Aurelian Florea wrote on Thu, Sep 15, 2016 03:58 PM UTC:

For some reason the AI pushes pawns very late.


Aurelian Florea wrote on Thu, Sep 15, 2016 04:40 PM UTC:

Also, there is no pawn initial double move. It gives an error. Move rejected by first chess program or something like it!


Aurelian Florea wrote on Thu, Sep 15, 2016 05:38 PM UTC:

What about Grand chess from where apothecary chess 1&2 take inspiration, wouldn't it have the same pawn problem?

I tried to set up the second game the same way and I sadly failed.

Here is what I got:

Aurelian Florea wrote on Thu, Sep 15, 2016 07:27 PM UTC:

I did all that and it works, but I'm afraid that now I took away the zebra as a promotion choice as I moved the zebra to the 8th rank!


Aurelian Florea wrote on Thu, Sep 15, 2016 08:02 PM UTC:

Well first, I decided to change the promotion rule to:

8th rank:less than a rook

9th rank:also to rook

10th rank: also to the 3 strong pieces

The reason for the initial rule was to not always promote to queen, but we got always promote to rook (I mean practically). The new rule is more flexible, but I'm afraid that it still leads to many rook promotions.

Second: the pawn double move still doesn't work, or it is something I did wrong?


Aurelian Florea wrote on Thu, Sep 15, 2016 08:04 PM UTC:

Oh! Ok, Silly me!


Aurelian Florea wrote on Thu, Sep 15, 2016 08:15 PM UTC:

Weirdly, no! Even pawns set back to the 2nd rank don't get the 2move!


Aurelian Florea wrote on Fri, Sep 16, 2016 03:13 AM UTC:

The thing with the executables happens to me, too. I can't get the new version working. But I'm willing to give it up, as the new promotion rule chages the game significantly and it's unimplementable in Fairy-Max. And I still haven't found a way to write the aanca and griffin in Skaak II.


Aurelian Florea wrote on Fri, Sep 16, 2016 03:44 AM UTC:

I managed on my own the easy task of rewriting the weirdPromotion script:

 

<script>function WeirdPromotion(x1, y1,x2, y2, promo)
{
  if((board[y1][x1] & 15) != 1) return promo; // moved piece is not a Pawn
  if(y2 == 9 || y2 == 0) return ((promo & 15) == 1 ? 9 : promo); // on last rank: cannot stay Pawn
  if((y2 == 7 || y2 == 2) && ((promo & 15) > 6))return board[y1][x1]; // rook or larger than Rook: remains Pawn
  if((y2 == 8 || y2 == 1) && ((promo & 15) > 7))return board[y1][x1]; // larger than Rook: remains Pawn
  return promo; // choice was acceptable
}
</script>

 

<script>function WeirdPromotion(x1, y1,x2, y2, promo)
{
  if((board[y1][x1] & 15) != 1) return promo; // moved piece is not a Pawn
  if(y2 == 9 || y2 == 0) return ((promo & 15) == 1 ? 11 : promo); // on last rank: cannot stay Pawn
  if((y2 == 7 || y2 == 2) && ((promo & 15) > 7))return board[y1][x1]; // rook or larger than Rook: remains Pawn
  if((y2 == 8 || y2 == 1) && ((promo & 15) > 8))return board[y1][x1]; // larger than Rook: remains Pawn
  return promo; // choice was acceptable
}
</script>

I've made the script chages as you've said. I'm still trying to run 5.0b. I redownloaded from the same link, pasted over what there was with copy and replace in both game directories and double pawn move doesn't work, I think because I'm not running 5.0b. Still working on that.


Aurelian Florea wrote on Fri, Sep 16, 2016 06:42 AM UTC:

Actually 5.0b is installed, but not working in winboard!
