Hi Greg:

Bad news. I followed your instructions completely but cannot run the app. Now the emerged window had a black background, no text and there was only a blinking cursor; the window header said:

C:\users\Carlos\downloads\ChessV2.2RC1\ChessV2.2RC1\ChessV.Engine.exe

Out of curiosity, I tried to do the same thing I did with Nebiyu, that is, to run it with WinBoard but the action was stopped.

It seems that I have no choice but to wait for the new ChessV version.

Thank you very much for all!

Okay, following your instructions, I was finally able to run the program. It's wonderful! 106 chess variants available!

Congratulations Greg. You have done an excellent job.

Thanks again for all your support!

You are welcome, Greg. Let's follow playtesting your masterpiece! Have you thought about developing a ChessV app for mobile devices, tablets and phones?

Those who are participating in the current tournament and are playing Symmetric Chess for the first time maybe might be interested in seeing how ChessV manages the matter.

Thanks, Greg, for answering. Hopefully soon some mobile apps developer could join and help in your ChessV undertaking.

I'm sorry to tell you that I have found these bugs:

1. In Ministers Chess setup the i-rook and the h-knight from White side are switched.

2. In Sac Chess both kings cannot castle.

3. When rotating the boards the numerical coordinates remain unchanged.

4. In Gross Chess the window size does not fit proportionally to the PC screen.

Aside of that, I'm enjoying immensely your masterpiece!

I have already downloaded the new version. Thanks again for your excellent work. I think the released date mentioned on your website has the wrong year.

Watch ChessV acting in all its glory!

Sissa is a compound of rook and bishop but its move is not disjunctive, it is conjunctive.

Conjunctive = A and B

Disjunctive = A or B

Am I right?

Thanks Greg. I would suggest that players could choose customize the piece set between abstract and alfaerie.

The one who edited the preset in use was me with some guidance from Fergus.

I have never seen the word 'compound' used in sequential meaning; I would say the Sissa is an (isosceles) hook mover. And I would not say the Tai Shogi Hook Mover is a (conjunctive) compound of two Rooks. The word 'or' usually implies 'and', and if you consider this operations on the move sets, the 'conjunctive compound' of R and B would have no moves (as B and R have no moves in common), and the conjunctive compound of K and R would be the Wazir, etc. There doesn't seem a case where this cumbersome way of describing more elementary move sets is useful, as they tend to all have simple names of their own. Note that the Sissa can neither move as a Rook, nor as a Bishop.

It seems to me the addition of 'disjunctive' serves no other purpose here then sow confusion in a case that otherwise would be correctly understood with 100% certainty.

Thank you very much, HG, for the clarification. Soon I will make the correction in what corresponds to the Sac Chess preset. It will take more time to do it in other texts because they are many.

What is paradoxical and anecdotal about this case is that I believed that making that distinction introduced clarity!

In passing, it should be borne in mind that 90% of what I write in English is "formatted"  [written, thought, said] by the Google translator.

@Greg,

 Thank you very much!

@Kevin,

The new preset page is already updated. Please let me know if you want us to write any particular text there. You don't have to worry about past game logs being affected because I have used another settings name.

@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.

How should the underlined parts be read (interpreted)?

def Aanca fn (checkride #0 #1 1 1 and empty #0) 
where #0 0 sign - rank #1 rank #0 
#1 
or fn (checkride #0 #1 1 1 and empty #0) 
where #0 sign - file #1 file #0 0 
#1
or checkleap #0 #1 1 0;

Particularly, what do the underlined  0 's mean?

def Aanca fn (checkride #0 #1 1 1 and empty #0) 
where #0 0 sign - rank #1 rank #0 
#1 
or fn (checkride #0 #1 1 1 and empty #0) 
where #0 sign - file #1 file #0 0 
#1
or checkleap #0 #1 1 0;

Thanks. I think we are close to finding the solution!

Then the question is how do we get the where operator returns the 4 options:

where #0 2 0

where #0 -2 0

where #0 0 2 

where #0 0 -2

Is there any other digit to use instead of 0 that fulfills the desired purpose? I mean the zero that I previously underlined.

What is easy to deduce is that the first backward line of code should look like this:

or checkleap #0 #1 2 0;

Is my assumption about the Osprey-Range definition correct?

def Osprey-Range mergeall 
leaps #0 2 0 
rays where #0 0 2 1 1 
rays where #0 0 -2 1 1 
rays where #0 2 0 1 1 
rays where #0 -2 0 1 1;

With the following code I have made some progress because the piece already can make the desired legal moves:

def Osprey fn (checkride #0 #1 1 1 and empty #0) 
  where #0 0 * 2 sign - rank #1 rank #0 
  #1 
  or fn (checkride #0 #1 1 1 and empty #0) 
  where #0 * 2 sign - file #1 file #0 0 
  #1
or checkleap #0 #1 2 0;
 

def Osprey-Range mergeall 
  leaps #0 2 0 
  rays where #0 0 2 1 1 
  rays where #0 0 -2 1 1 
  rays where #0 2 0 1 1 
  rays where #0 -2 0 1 1;

However something must be wrong since the program allows the Osprey to be moved as ferz. What do you think is the cause?

Yes, but then how to explain that the program allows moving the piece like Ferz?

Interesting deduction, Ben. Let's see what Fergus thinks.

Set. Problem solved. Thank you very much for your help, Fergus.
