At playchess.de, we now have conditional moves (CM). However, these CM
deviate from what is known from traditional correspondence chess: the
conditional moves you enter are *hidden* from your opponent.
I would like to get some feedback from experienced (correspondence)
chess players. What do you think about this implementation?

Following is an excerpt from the description at www.playchess.de:
A conditional move is a move that you plan as a reply to a certain move
of your opponent. For example, if you have Black in a freshly started
game, you plan to answer c5 if he plays e4. And if he continues with
Nf3 you would answer that move with d6.

You can advice the PlayChess server to make these conditional moves (c5
and d6) for you. But if your opponent deviates from your conditional
move sequence (by not playing 1.e4 or not playing 2.Nf3), the PlayChess
server will not do anything. Instead, you will have to enter your move
yourself, just as you normally would do.

If the PlayChess server finds your conditional moves, it automatically
makes them for you, as long as the game follows your expectations. The
server just makes your planned moves, nothing else; it does not
"invent" its own moves. However, it makes your moves immediately, since
it is always "on line".
