+1 with Keano and BladezII: 7.Nge2 main move

@BladezII: at move 7 because Rasje's post is about inserting Bg5 and Nf6. Tartakower (and later Larsen) 's variation in the French Exchange: 4.exd5 exd5 5.Qf3 vs Pillsbury's variation in the Classical French (Winawer) Exchange 4.Bg5 Bb4 5.exd5 exd5 6.Qf3

6.Qf3 Qe7+ 7.Ne2 and now

A) 7..Nc6 8.ooo Be6 += (my own assesment, merely because White can double safely pawns in f7-f6 where as double pawns c2-c3 are supporting d4 in some lines)

B) 7...Bg4? 8.Bxf6 Bxf3 9.Bxe7 +-

C) 7...Qe4!? 8.ooo (same idea as line A)) Qxf3 9.gxf3 Be6 10.Nf4 (now the knight unblocks White center, but queens have been exchanged and the "weakness" f2-f3 has counterpart with excellent f4 square for knight) Bxc3 11.bxc3 Nc6 12.Bxf6 gxf6 13.Kd2+=

D) 7..Be6 8.a3 Ba5 = maybe safest line for Black with ...

E) 7..Bxc3+ 8.bxc3 Nbd7 =

Long castling is the point for White in other lines:
6....oo 7.Bxf6 Qxf6 8.Qxf6 gxf6 9.Ne2 c6 10.ooo (Suetin) and 6...Nc6 7.Ne2 Be6 8.ooo

1. e4 e6 2. d4 d5 3. Nc3 Bb4 4. exd5 exd5 5. Qf3 Qe7+

6. Nge2  (you have this as move 7; it should be move 6 )

6...   Nc6  ( this is the best reply )

This is what both Williams and Watson recommend now.  Black gets a very nice game here.

7.Ne2 seems the way, your 7...Be6 doesn't seem to do it.

But 7...Qe4!? is one possibility played by a couple of strong players. Both sides will end up with doubled f-pawns and the game goes on.

In the Winawer you have a line which goes like 1.e4 e6 2.d4 d5 3.Nc3 Bb4 4.exd5 exd5 5.Qf3 (Larsen) and now Qe7+!. This seems to be good for black, disrupting white's development. Both Dvoretsky in 1995 (Secrets of opening preparation) and recently John Watson (Dangerous weapons: the French) wrote about it, although Watson played the devil's lawyer  Cool (don't know if this is a regular expression in English, it is in Dutch) and avocated the system for white. Simon Williams and, again John Watson, defended the black side in Attacking chess: the French and Play the French, 4th edition.

Now, in the variation 1.e4 e6 2.d4 d5 3.Nc3 Nf6 4.Bg5 Bb4 5.exd5, nearly everyone playes Qxd5, which is a good move of course. But why not 5...exd5? Because after 6.Qf3! white threatens Bxf6, crippling the black structure. Recently Aagaard and Ntirlis also embraced 5...Qxd5 in their, very good, book about the French. And indeed, doesn't black has to play 6...Be7, losing a tempo, and can't white simply continue with 7.Bd3/Nge2/0-0-0 and/or (7).h3 ?

Well, maybe there is another disruptive move here after 6.Qf3, 6...Qe7+!?. A short analysis without the engine convinced me it seems playable:

A. 7.Be3?! Ne4
B. 7.Be2 Bxc3+! 8.Qxc3 Ne4! (the point) 9.Bxe7 Nxc3 10.bxc3 Kxe7 or 10.Bb4 Nxe2 11.Nxe2= (not very fun, I admit). Or 8.bxc3 Nbd7 (8...Be6) and h6/g5. Maybe 7...Nc6 8.0-0-0 Be6 with a complex position?

C. 7.Ne2 just seems to block the B on f1. 7...Be6 8.Bxf6 gxf6 9.a3 Ba5 of Bd6, complex it seems.

Of course there are many other tempting possibilities in this variation, this is just a start. Don't know if it is a novelty.
