I remember there being a way to save and load games for the interative diagram. I cannot find where. Any ideas of how to do it?

While playing my 12x12 variants I have noticed that besides the material type owned by the opposite side, the imitator's power is also greatly affected by the number of different types the opponent has. What is your guys take on this?

This game, like Gross chess has promotion limited by rank. Bishops are easier to promote earlier in the game.

Well I can manipulate the captured pieces array. I did that before! Thanks!

But how do I put 2 bishops in the supply array?

OK, Thanks

No, it does not work with (P 10 p 10 X 10 x 10) nor with (P p X x)

@HG There is also a peculiar situation in the Grand Apothecary chess games given by the brouhaha squares. Technically pawns should not reach there and that is easily done by adjusting the promotab so that you are forced to promote before reaching the brouhaha squares. But I'm not sure how easy it is for the interactive diagram.

That is great. I'll be testing it soon!

@HG,

On the previous rank the promoting pawn basically has a sergeant power (fWfA). This is to difficult to stop in my opinion.

Thanks, HG!

A problem might be that if you allow both Pawn and Berolina as promotion choice, you don't only allow Berolina to promote to Pawn and vice versa, but you also allow Berolina and Pawn to stay themselves. Since the choice would make no sense on the last rank, where neither of these would have any moves, I suppose this is not a problem, but rather exactly what you want.

I don't see the way to ban promotion of regular pawns to berolina pawns and vice versa.

I think I have found a bug in the diagram below:

The AI, while playing black, promotes to rook at rank 4 (1 being the brouhaha rank). It supposed to de able to promote to rook since the 3 rank downwards. The weird thing is that I checked it manually with the diagram and it worked fine. The trouble is only when the move button is pressed.

Thanks for the clarifications, HG

@HG

In all my 3 Grand Apothecary games pawns do not promote, except to other pawns. I have identified the error coming from the supply vector. It is defined like this:

set supply (P p X x); // in infinite supply

But not the other pieces that are there initially. How do I fix this as the interactive diagram works well.

And by the way, also the regular pawn is able to promote to berolina and the berolina to regular pawn. Is that fixable?

It is just that I remember an older discussion. Thanks for clarifications!

@HG,

It is really annoying that the imitators are traded for nothing. Maybe you can do something about this when you find the time, like when the move button is triggered the value of the imitator is updated with the average of the values of foe pieces.

@HG,

All my tests are working. Thanks!

It seems we are almost there. The 4 squares to the left castling with the rook should also be suppresed.

There is no error now but the short 3 squares castle with the rook still deletes the rook while jumping the cannon over the king!
