@Zatara:
Coming back here after long holidays,I see that you don't have reply....I try do post one.
Lines played by Morozevich in the French ? do you have chess database software ? or internet ?
it's SO EASY to do it yourself instead of asking other people to do searching work for you
after one google search: "chessgames Morozevich" then Google retrieves you in one second the URL:
http://www.chessgames.com/perl/chessplayer?pid=11719where you have games from Morozevich
Arg..i have just read SF post deleting url GM William website...please moderator, keep mine,
, chessgames is the only free online database I know and it is no commercial website "I think that Watson has some stuff..." why guessing ? is it a way to ask a question to J.Watson, why not send him PM or email ? have you bought his book "Playing French 3" ?
but if you want only the answer: NO
J.Watson covered in chapter Fourteen, only the Burn variation 1.e4 e6 2.d4 d5 3.Nc3 Nf6 4.Bg5 dxe4 5.Nxe4 Be7 (not 5...Nf6 as you write) 6.Bxf6 (not 6...Nxf6 ) Bxf6

Last Psakhis's book I have
French Defence - Steinitz,Classical and Other Systems
ISBN 07134 8941 3
2004
Batsford (Chrysalis group)
URL Chrysalis website deleted ... i must be logical myselfdeals about it: chapter 6 Burn Variation ... 6...gxf6!? pages 97 to 111
OFWATA 6 Khalifman book deals about it in chapter 4: pages 68 to 72
Is it a good line ?common answer from me: "yes if you win with it"

more uncommon: "yes for White"
or: "yes for Black"
or: "yes for good player"
or: "yes for hard working player"
or: "yes for chesspub member" (I am sure this one will enjoy one Grand (web)master

)
and so on
and seriously: "if the line is not enough good for Black you can be sure it will be written in one book with 6...gxf6?! or 6...6...gxf6? and line appears not so often in recent games"
