There was a Survey in Chessbase Magazine 178 featuring our Pet Line, and among the analysed games was one highlighting a problematic move-order for us:
1.e4 e6 2.d4 d5 3.Bd3 dxe4 4.Bxe4 Nf6 5.Bf3 c5 6.Ne2 Be7! This unassuming little sixth move is quite an annoying finesse against our line, and not even the variation's greatest specialist Vladimir Onischuk has been able to find a convincing answer. Black's idea is to defer the capture on d4 until a better moment, while at the same time limiting White's attacking options as you will see.
I had been aware of this problem line since 2017, the year of the article, but quickly forgot about it since the Tarrasch was and is my main weapon against the French. However, motivated by our course, I was planning to surprise an upcoming opponent with the 3.Bd3 variation, until checking my files refreshed my memory.
Since 2017 the line continues to score well for Black at all levels, so we the ChessMood family must rise to the occasion and find a way to reverse that trend :-)
Here is the game from the Survey with the authors notes in both English and German:
