That's true, but it does not mean that the protocol could be improved.
Winboard could receive the command "claimdraw move" and send
move
1/2-1/2
to FICS and ICS since these servers do it wrong. When the servers improve
their protocols, winboard is ready as well all the compatible engines.
Besides, I wonder if sending those two commands in batch, Winboard could
improved any possible race condition in the server (before the opponent
replies).

Not under FIDE. 6.1 "The move is completed: in the case of the transfer of a
piece to a vacant square, when the players hand has released the piece"
and some other examples.

It is different under USCF (probably, the only place in the world) where
there is a distinction between move "determined" and "completed" (includes
punching the clock) (rule 9g, 9g1 and 14c2, 14c4). USCF rules are kind of weird
because it allows the claiming after moving but it is strongly discouraged and
not recommended. There is even some contradiction if we read carefully.
My comment: it is even dangerous to claim in this way. You move and do not
punch the clock. Well, what if a reply immediately on the board? I just say
that you forgot to punch the clock. I would not want to be involved in that
mess...

So Korchnoi did not do it wrong because it was in a US open (aren't US Open
suppose to be played under FIDE rules so it can be FIDE rated? I wonder)
Anyway, I would not learn rules from those super-GMs. They many times
get away with things that no other will.

Miguel
