Chess error #105

Closed GreenXenith closed 5 years ago

I believe this is different than #104.

There is chess AI branch I’m working on which fixes that. But got no time to finish it.

You can place a king (incorrectly) into check (illegal). After that, the next move will trigger this error. The code that crashes at line 5 is fine, the whole situation should not have happened, I think.

Please check if the issue can still be reproduced.
