Sometimes castling works and sometimes it doesn't. Why?
It was always the case on 'Live' that to castle you needed to move the King first, then wait for it to register, then move the Rook. Failure to follow this procedure resulted in embarrassing Rook only moves!
On 'Play' you would expect this would also work but it is now all a bit random if it does. It looks like the reason for this is the way smart boards work on the page. Every time the physical board changes the new board position is sent to CDC as a FEN string. CDC then works out what to do with it and either makes the move or it ignores the string.
The reason a new FEN may be ignored is because when a game is being played lifting a piece off the board to move it to a new square will generate a new FEN string. That position is obviously illegal within the context of the game.
The solution. Lift up the King and move it to the castling square VERY, VERY, FAST! If you catch it at the right millisecond castling will work. If not put the King back and do it again. NEVER move your Rook until castling has happened on CDC.
Castling is hardly an edge case and I would say that this needs to be fixed by CDC. I think (and this is just a guess) they need to ignore all FENs without 2 kings on the board.
