Nobody must code it in order to participate in WCCC.

The engine can play chess also in console mode without knowing to detect illegal
positions.

I think that every winboard engine or UCI engine is allowed to use the chessbase
interface in WCCC.

I remember that amateurs like Jonny and Falcon used the chessbase interface in
the world championship in Israel.

I did not do it because I did not like the interface to claim a draw for me.
I thought that arena is better in this respect but I also did not use Arena
except the draw against woodpusher because arena claim a draw in words that
Movei does not use and I found the draw claim of movei only in the logfile.

I do not think that it changes much.

I am not sure about it and I think that speed is overestimated.

Even if Fritz can be 10% slower if you add the code(I doubt it) then it is
translated to less than 10 elo at long time control.

I do not support chessbase and I dislike things that they do like not allowing
games of more than 300 moves.

In case that Movei becomes commercial
I will probably not sell my engine to chessbase because I think that they have
too many bugs in their interface.
