Dear user,

'bc4' is an invalid move, both in algebraic notation (see
https://en.wikipedia.org/wiki/Algebraic_notation_(chess)), which uses
uppercase letters for figures, and in coordinate notation (see
https://en.wikipedia.org/wiki/Chess_notation), both systems supported by
GNU Chess. A correct move in the given position good be:

Bc4 (algebraic notation)

or

f1c4 (coordinate notation - rarely used in human readable chess
publications)

The same holds true for the other attempts to move the bishop 'bd3' and
'be2'.

Hence I think that GNU Chess was right when it complained. I just verified
it on version 6.2.1, the latest stable version.

However, before version 6.2.0, the program was permissive with piece names
except precisely for the bishop. This means, that lowercase letters were
accepted for all pieces except for bishop, which had to be uppercase at any
rate. I think that this may be what you are experiencing.

Our general recommendation is always to upgrade to the latest version
(6.2.1), and use the algebraic notation as is. If you need to stick to your
current version, you must use 'B' for bishop.

Thanks for your interest and do not hesitate to contact us again.

Regards,
--Antonio Ceballos
