I think your opponent needs to change his literature or stay off the pot
To me your Bb4 seems decent (though indeed c6 may have been even better) and to me it looks like white should be thinking about equalising. Also the Qd7 idea looks good as you can follow up with f5 after an exchange of bishops.

If you play the French, then 3...e6 is a good choice. 4.e4 will transpose to a Classical French, but many Veresov advocates will understandably seek something different. However, White's alternatives to 4.e4 are at least equal for Black, as he can continue with ...c5! at some point.

Okay I've only ever had to play this line twice so I have no experience in it.. somehow I managed to stumble through book lines OTB.

My opponent after the game though commented that one of the mainlines should always lose for black.
1. d4 d5 2. Nc3 Nf6 3. Bg5 Bf5 4. Bxf6 exf6 (I understand gxf6 is the better line here with the intent to castle queenside - extra pawn in center open g file for rook) 5. e3 Bb4? This is the move my opponent claims is a horrible mistake (though the books i've found list this as a mainline). He states black can only play 6. c6 or 6. Nc6 here. While I admit I didn't get much from this move in the game... I did go on to win the game so it can't be all that terrible. Another move I thought about though was playing 6. Qd7...I liked this move alot because if he goes for the idea of trading light square bishops with 7. Bd3 then I can just develop because if he trades the Queen takes a better square. It also leaves him in the dark as to whether I plan to castle kingside or Queen side. and lastly my N is clearly not heading to d7 so the knight has not lost its square. Is there a reason Qd7 is not played? I have found no games with it. I assume the c6, Nc6, and Bb4 are all better plans for black?


And for the record my opponent went on to play 7. Nge2 which is also not book as far as i'm aware.

Anyone here know the Veresov real well? It feels like a very transpositional opening.
