Still something strange happened, because it would never play a move when it says resign. That it doesn't print 'I resign' is indeed no big deal, but if that doesn't work, there is no telling what else might not work, so it had me worried a bit. Great that it works now, let's hope it stays that way, for everyone.

@ H.G.: Today I tried the sequence 1.Nb4 Ka7 (illegal) 2.Qa6 (illegal) followed by clicking on 'Play it!' and then 'Move'. This time I noticed it printed out 'I resign' (highlighted in red), a bit ABOVE Carlos' diagram.

I suppose it's possible I missed 'I resign' on most of my earlier test tries simply because I was looking for the words 'I resign' below the diagram instead, i.e. where the moves 1.Nb4 Ka7 2.Qa6 were printed out. Otherwise, I'm still not sure why Black's king took my queen consistently on the first day I tried the test. Anyway, I can live with it even if there is a bug somewhere, rather than my hallucinating. Thanks for the help!

If nothing happens at all, the script might have stopped because encountered an error, and in that case it would be possible to get information about it. Just hit the F12 key after you pressed 'Move' and nothing happened, and an area will open at the bottom of your browser window, with a number of tabs in it. Select the tab 'Console' if that is not already selected. Error messages should appear in there. You can close the area again by another F12.

I wrote something and discovered I wasn't logged in at the time I finished the post. Hopefully it can be recovered by an editor.

Now when I try entering 1.Nb4 Ka7 (illegal) 2.Qa6 (illegal) and then click on 'Play it!' followed by clicking on 'Move', nothing happens at all, not even an 'I resign' message. I tried this 3 times tonight and it happened 3 times that way.

I suppose when I originally saw the Black king take my Queen the first day I tried this test, something may have been different.

On the other hand, I have been told I have schizophrenia, since once in a while I see things incorrectly (such as words) now and then (for example) - though I've never seen a chess or CV position incorrectly, when I've been awake, as far as I know.

I'm not sure how to check which exact version of MS Windows Explorer I have as my browser, if that would help instead.


H. G. Muller wrote on Sun, Aug 2, 2020 05:34 AM UTC in reply to Kevin Pacey from 12:02 AM:

I am also running Windows 7 (on a desktop). I tried it with MS Internet Explorer (update version 11.0.170), but I still get the 'I resign' message. This makes it a complete mystery.

Does anyone else have this problem with the Diagram?

That the piece values differ slightly from run to run is normal; the diagram determines those by sampling a number of randomly generated positions.


💡📝Kevin Pacey wrote on Sun, Aug 2, 2020 12:02 AM UTC in reply to H. G. Muller from Sat Aug 1 07:16 AM:

@ H.G.: I'm using a MS Explorer browser (from my Windows7 laptop).

When I did what you suggested as another test, the value displayed for the king was '311 (c00)', so it would seem that it's considered royal, according to what you wrote.

[edit: Note that when I did the test a second time, the pieces were given slightly different values for some reason. For the king, '316 (c00)' was given, for example.]


H. G. Muller wrote on Sat, Aug 1, 2020 07:16 AM UTC in reply to Kevin Pacey from 01:51 AM:

That is odd indeed. What web browser are you using? I tried it with FireFox and Chrome, and in both cases it said "I resign" without moving.

One other test we can do: when you open the piece table by clicking on "here" under the diagram, and then click on the "move" header of the move column, it should switch to displaying the piece values it estimated. (Don't take those too seriously! They are often very inaccurate, but good enough for playing against someone who desn't know the piece values either.) Behind the King it should also print "(c00)", though, to indicate that it is royal. One of the explanations for what you see is that it somehow did not get through that the King is royal.


💡📝Kevin Pacey wrote on Sat, Aug 1, 2020 01:51 AM UTC in reply to H. G. Muller from Fri Jul 31 11:29 AM:

That's odd. Just now I entered the moves 1.Nb4 (square lit up as usual) Ka7 (illegal) 2.Qa6 (illegal) and then clicked on 'Play It!', and next I clicked on 'Move'. At that point the Black king took my queen on a6.


H. G. Muller wrote on Fri, Jul 31, 2020 06:58 PM UTC:

Note that the castling move that is now defined for the King (isO2) describes castling with the furthest piece in that direction. Which in this case is the Judge. If you would want it to castle with the Rook you would have to specify isjO2 . (I used the j for this, which normally means 'jumping', because in a sense you jump over the Judge while looking for the castling partner.)

For user input the diagram is not very pedantic, and allows you to castle with the Rook anyway, but it allows every other illegal move as well, so that doesn't mean a whole lot. As it is the AI would never castle with the Rook, however.


H. G. Muller wrote on Fri, Jul 31, 2020 11:29 AM UTC in reply to Kevin Pacey from 03:15 AM:

This is definitely not as it is supposed to behave. The chekmate detection does seem to work, though, as can be tested by first playing the (illegal) moves 1.Nb4 Ka7, then switching on the AI and playing 2.Qa6. It then says "I resign" without playing a move. After it lost its King, and it is its turn to move, it should say "It seems I have already lost".

No idea why that wouldn't have worked in the game you played. That it doesn't see mate-in-1 coming is normal; the default lookeahead depth is only 2 ply + quiescence search, and for mated-in-1 the King is only captured on ply 4. (So 3 ply + QS would be enough to see it.)

In any case the play will be quite weak; it is intended to be a demo for people who just have seen the rules for the first time, to get an idea what the game is like. Setting it to 4 ply would make it slightly tougher, but even then a strong player should not have much dificulty beating it. (An for large games like SAC Chess it might think too long.)


💡📝Kevin Pacey wrote on Fri, Jul 31, 2020 03:15 AM UTC:

I played it a complete game, though I didn't save it. It may have been on a very low number of ply look-ahead (i.e. the default level). I don't know if it's a bug, but when it let me checkmate it in one move, the losing king took the mating piece attacking it one square away, and it continued the game after I took its king (at which point I abandoned the game). Presumably playing it using several ply look-ahead higher would give me a much tougher time.

OK, you are welcome.

Thank you Carlos! I will try to play it sooner or later!

Kevin:

I configured the Muller's applet to play your variant. Hope you like it and find it interesting to face its AI. For me it is a great resource to enjoy doing something that I like.

I share the next game I played vs it driving me the white side.

King, Queen, Rook, Bishop, Knight and Pawn are labeled as usual. The remain thus:
Amazon: A
Marshall: M
Cardinal: C
Sailor: S
Missionary: M°
Judge: J

I renamed the Archbishop as Cardinal so I could use the A to label the Amazon.

Thank you very much!

Ok, that's fixed.


Carlos Cetina wrote on Tue, Jul 14, 2020 06:41 PM UTC:

@Greg:

I just noticed that in both standard and alternate piece sets the labels for Sailor (R+F) and Missionary (B+W) are reversed.

They are currently incorrectly labeled thus:

Alt text for a graphic image = M

Alt text for a graphic image = S

They must be correctly labeled thus:

Alt text for a graphic image = S

Alt text for a graphic image = M

Could you please take a look at it?


💡📝Kevin Pacey wrote on Sun, Jul 12, 2020 08:21 PM UTC:

Okay, thanks. I hadn't realized the implications of that default checkbox.

Incidentally, Tim O'Lena recently submitted a couple of Zog-related submissions to be looked over by editor(s), in case you missed that.

I just unchecked Uses HTML for you. You should check that only if you are completely depending on HTML to describe your page's formatting.


💡📝Kevin Pacey wrote on Sun, Jul 12, 2020 06:22 PM UTC:

I slightly edited the rules page for Sac Chess, by noting in the introduction that there are (now) 3 rules enforcing presets available.

Unfortunately, it seems the Sac Chess rules page formatting has become messed up, once more.


💡📝Kevin Pacey wrote on Sat, Jul 11, 2020 02:47 AM UTC:

Yes, it appears the formatting issues with all my submissions that were messed up previously (somehow) have been nicely resolved, by one or more of the editors it may well be.

The only possible exception might be with the Notes Section of my Full House Hexagonal Chess rules page - unfortunately I cannot recall if I left sparse/no spacing between what perhaps should be independent paragraphs in the Notes section to that rules page, so perhaps fixing it further, if it should be fixed further, might take some guesswork or arbitrary editing.


Carlos Cetina wrote on Fri, Jul 10, 2020 05:53 PM UTC:

You are welcome, Kevin.

The formatting issues seem to have been fixed. It only remains to mention that the available presets are three.


💡📝Kevin Pacey wrote on Mon, Jun 29, 2020 12:04 AM UTC:

@ Carlos:

Looks good, thanks!

@ Greg:

The Sac Chess rules page is not the only submission of mine that has gotten messed up, due to some formatting changes to CVP's database perhaps. I wasn't in a hurry to draw attention to all of those submissions, in case the onus somehow fell on me to modify what used to be well-formatted submissions of mine.


Carlos Cetina wrote on Sun, Jun 28, 2020 11:39 PM UTC:

@Greg,

The key at the bottom that describes the pieces shows Alfaerie images.

 

So is. I already corrected it. I even put links to the three presets separately so that the player who is going to launch an invitation can choose the one he/she likes.
