Alumbrado and all,

You asked about whether the inclusion of ...Nf6 and Bg5 was so important in the Exchange French.

Theoretically (I don't know about practice), Black should want to develop his Ng8 to the opposite square of the Ng1.  So, when White plays Nf3, Black should play Ne7 and vice versa.  With Black already committed to Nf6 and his Bishop already aggressively posted on b4, White can gain an advantage by a direct king-side attack including Nf3, Bd3 (usually), and Re1.

Again, this is all theoretical (supported by comments made by Korchnoi, Watson, and others).  Specific lines may disprove this theoretical point, but I don't think so.

Yes, interesting game..White wins a pawn but some moves to put the queen to the right square: (Qg4-Qg7-Qxf6-Qf4-Qd2 vs Qd2).
The idea does'nt work in the Qd2 line: 8.Qd2 Bd7? 9.c4 Qe4+ 10.Ne2 Ba4 11.ooo Na6 12.Nc3 Qc6 13.d5 Laketic-Borges,Belgorod 1990 (Psakhis) or 8.Qd2 Qe4+ 9.Ne2 Bd7 10.ooo Qd5 11.Qf4 Qxa2 12.Qxf6 Rg8 13.Nf4 Smirin-Korzubov,Minsk 1985 (MCO)

Really not too many games played in the Qg4!? line mentioned by alumbrado. Glek treated it (speculatively?!) with Bd7 in 2001, which looks interesting:

[Event "Bad Woerishofen op"]

About Qxd5?! line...
5...Qxd5?! 6.Bxf6(6.Nf3 Ne4! Lasker-Znosko Borovskij, Saint Petersburg 1909 (ECO) or Schlechter-Mashall,Ostende 1907 (Suetin) or Savon-Glek,Odessa 1989 (MCO)) Bxc3+ (Alekhine's idea which worked well in Capablanca-Snosko  Borowsky St Petersburg 1913,but later Qd2 what discovered) 7.bxc3 gxf6 8.Qd2! (or Qg4!? given by alumbrado) Capablanca-Alekhine,NewYork 1924 where 8...Nc6!?  (MCO) has to be tried

I advice:
5...exd5! anf if
A) 6.Qf3! (Pillsbury's attack) Be6!? (Dom)
B) 6.Nf3 look at Capablanca-Labatt,New Orleans 1909
C) 6.Bd3 Nc6 or 6...c5 Capablanca-Corzo,La Havanne 1913
D) 6.Qe2+!? Be6 (Dom) 7.Qb5+ Nc6 8.Bxf6 (8.Qxb7 Nxd4) gxf6=

C01, C12: MacCutcheon Exchange

What - if anything! - do people think of the line 1.e4 e6 2.d4 d5 3.Nc3 Nf6 4.Bg5 Bb4 5.exd5!? ?

Given that White doesn't seem to be getting anywhere in the main lines of the MacCutcheon, I am surprised this doesn't get more outings.

There are two options for Black:

I. 5...exd5
In his Main Line French, Pedersen simply states that 5...exd5 is "a version of the Exchange Variation with which White can be happy" but offers no analysis.  It is not immediately clear to me why White should be much better off here than in the 'normal' Exchange or the Winawer Exchange [do the moves ...Nf6 and Bg5 favour White so much?].  I suppose 6.Qf3 is a try for White.

II. 5...Qxd5
The most popular choice.  Then 6.Bxf6! Bxc3+! [6...gxf6?! 7.Ne2! is good for White eg 7...Nc6 8.Qd2! Bxc3 9.Nxc3! Qxd4 10.Qxd4 Nxd4 11.0-0-0!] 7.bxc3 gxf6 8.Qg4!? and Pedersen feels "Black may have trouble equalising".

Do Black players have anything lined up against this?  Any thoughts welcome!
