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.

H.G.

"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!

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?


Aurelian Florea wrote on Thu, Sep 15, 2016 06:25 PM UTC:

H.G.

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

Here is what I got:

Initial position:

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.
