Help required..Maybe a bug?

[Steve]

Hello,

I have just downloaded PyChess and was playing a quick game to see how it worked. I suddenly got a message at the bottom of the screen "Stephen won the game because of adjudication by an admin invalid engine move:e8g8".

Not sure who or what the admin is as I was playing just against the computer, but nevertheless, the computer was castling, neither pieces had been moved before, it wasn't in check, it wasn't passing through check nor would it end up in check. I can't see why it was an invalid move?

I have attached a screen-shot. Perhaps I am missing something. I haven't played in a very long time.

Thanks

Steve.

Hi Steve!

From attached picture I think you started a new game from a given FEN position.

Maybe that castling rights was not checked in? Btw. is this reproducible?

Hi Tamas,

Sorry, I don't know what a FEN position is. I did start the game from the setup position screen. I'm guessing that's what you mean. On That screen (which I now see has FEN at the bottom). I can't see a button that mentions castling rights. Unless it has something to do with the 0-0 and 0-0-0.

Sorry for being a bit dim.

Hi Tamas,

OK I have just tried it with those 0-0 0-0-0 boxes ticked. It has castled successfully and the notation shows 0-0. Sorry, I didn't know the notation. Now I can see it, it's blatantly obvious. Last time I played against anything that showed moves, it would have been shown the way the error was flagged up e8g8. The only way you can achieve that is through castling. Never seen 0-0 before.

Anyway the main thing is everything is working as it should. Except the pilot obviously.

Thanks for your reply and giving me the insight that I needed to enable castling.
