Blackmar-Diemer Gambit 5.Nxf3 e6

The Blackmar-Diemer Gambit Euwe Variation 5.Nxf3 e6 remains one of the most logical defenses for Black against the aggressive opening. This chess gambit blog post serves as a basic introduction to 5...e6. Next month I'll cover a different variation.
Below are 10 games played in the past few years that I have not analyzed previously. Each game includes one or both players rated 2200 or above.

For an expanded look at the 50 games (105 diagrams) I did last year, see my new book Chess Chronicles: Blackmar-Diemer Gambit and Other Chess Games

1.d4 d5 [This is the Queen's Pawn Opening, a very common and classical choice. Both players are fighting for control of the center.]

2.e4 [White deviates from the usual Queen's Gambit lines, playing the Blackmar-Diemer Gambit. This move challenges Black's central pawn immediately.]

2...dxe4 [Black accepts the gambit, taking the pawn. This opens up lines for both players.]

3.Nc3 [White develops a knight, targeting the e4 pawn and preparing to regain material while developing pieces. This is Diemer's improvement over Blackmar's 3.f3.]

3...Nf6 [Black develops a knight, defending the pawn on e4. This is a common and solid developmental move.]
4.f3 [If allowed, White aims to recapture the pawn on e4 with the f3 pawn, opening up lines for the king's bishop and rook.]

4...exf3 [Black decides to exchange the pawn and thereby remain a pawn ahead.]

5.Nxf3 [White recaptures with the knight, keeping a strong presence in the center and preparing for kingside castle. 5.Qxf3 is very tricky, but objectively, it is better to take on f3 with the knight.]

5...e6 [Black solidifies their pawn structure and opens lines for the bishop to develop, potentially to d6 or e7.]
[Now, both 6.Bg5 and 6.Bd3 has its own strategic merits and sets the stage for a dynamic middle game. I'll deal with 6.Bd3 first and 6.Bg5 second.]

6.Bd3 [This move develops the bishop to a strong central square, eyeing the h7 pawn. This is more about building up a strong central presence and preparing for a possible kingside attack.

6...b6 
7.0–0 Bb7 8.Be3 (White protects d4 since the Nf3 is under fire) 8...Be7 9.Qe1 Nbd7 10.Qg3 Nh5 11.Qg4 Ndf6 12.Qh4 g6 13.Ng5 Qd7 14.Bb5 c6 15.Bc4 h6 16.Nxf7 Kxf7 17.Ne4 Kg7 18.Ng3 Nxg3 19.Qxg3 Rae8 20.Bd3 g5 21.Bxg5 hxg5 22.Qxg5+ Kf8 23.Rxf6+ Bxf6 24.Qxf6+ Kg8 25.Qg6+ Qg7 26.Qxe8+ 1–0 Christensen - Popov, chess.com 2020

6...Be7 7.0–0 0–0 8.Qe1 and now:

And now for the more popular 6.Bg5 (and my personal favorite.)

6.Bg5 [This move pins Black's knight to the queen, adding pressure on Black's position. It's an aggressive move, aiming to control the knights and create potential threats against Black's king.]

    As far as I know, 5...e6 is very passive for Black. I usually win against the Euwe Defense.

    Yes, in practice that is true. In theory, a well-timed ...c5 or ...Nc6 can put up stiff resistence and sometimes steal the initiative away from White. But most people fail as Black. Tim

    I have played against 7...c5 and 7...Nc6. Most of the time I won.
