But I don’t like facing that ...Bd7 stuff that Williams’s repertoire book advocates.
I have no idea about the current theoretical status of the ...Bd7 and ...f6 lines, but there is a feeling that Be2 is a more useful move than a3, so it's harder to believe Black is fully OK after 6.Be2 f6.
I tried to follow Williams back when only the DVD (The Killer French) was out. There one main line recommendation was 5...Bd7 6.Be2 Nge7 7.0-0 Nf5!?, when the critical independent try for White is 8.Bd3 (8.Na3 instead transposes to other lines). After 8...cxd4 9.Bxf5 exf5 10.cxd4 Williams reached a standard position type (that Moskalenko is a big fan of). But he didn't mention 10.Nxd4! instead, which leads to a very "un-French" position that looks uncomfortable for Black to me. Though I know Antic and Maksimovic try to defend Black's cause here in their repertoire book.
P.S.: The contents of
The Killer French is now also an eBook, and the free excerpt just happens to contain the parts on the Advance!

About French, as white I have tried the Kupreichik variation (1.e4 e6 2.d4 d5 3.e5 c5 4.c3 Nc6 5.Be3) in several games.
The funny thing is that in each game my opponets was out of book very early and I usually got the better position out of the opening even if I lost the game or if the game became a draw. Only problem is of course that the line can not be forced since Qb6 instead of Nc6 rules it out.
At one point I believed I had found good replies to the Kupreichik, but it's played so rarely I would probably have forgotten my lines when I finally faced it! So yes, if Black uses ...Qb6 lines it is tempting to just rule the Kupreichik out with 4...Qb6. ...Bd7 fans don't have that luxury.
