Front cover design by: https://www.fiverr.com/pro_ebookcovers Table of Contents Introduction This Blackmar-Diemer Gambit book shows how I win after 1.d4 d5 2.e4 dxe4 3.Nc3 Nf6 4.f3 exf3 one of my favorite chess openings for entertainment value. I illustrate strategy from my games vs random Advanced players as Guests on chess.com.

The book has 42 games with 174 diagrams. I scored +41 -1 =0 in these 10-minute blitz speed games. I play White in all but three games. In one game I snatched defeat from the jaws of victory. This gambit works well vs intermediate chess players. Opening theory and endgame knowledge help your play, but tactics win most games.

I use strategy for my comments to explain whats going on. I follow any of these steps. 1. Describe the current position. 2. 3. 3.

Plan how to get there. I pick a key position every few moves to make a comment. My plan is for you to browse through the book, look at the diagrams and read the comments with ease. For those who prefer to read quickly, you can skim through the book from diagram to diagram. Note the change from the previous diagram and read any notes that interest you. From time to time, I add a line of analysis.

You may wish to work out some of those lines in your head, or just note that there was an alternative way to play and keep reading. I played chess for 50 years. As a correspondence master and blitz master, my usual opponents were rated 1800 to 2400. My opponents here are often lower to intermediate. I assume that you can read algebraic chess notation. The diagrams have White at the bottom of the board.

Thank you for reading my books. I hope you enjoy this one!

Chapter 1 1.d4 d5 2.e4 dxe4 3.Nc3 Nf6

Game 1 [4.f3 Bf5 5.fxe4 Bxe4]

1.d4 d5 2.e4 dxe4 3.Nc3 Armand Blackmar played 3.f3 in the late 1800s. Blackmar was chess club treasurer in New Orleans when unofficial World Champion Paul Morphy was president of the chess club (after their Confederacy lost the American Civil War). 3...Nf6 Emil J. Diemer improved on 3.f3 by inserting first 3.Nc3 so that 4.f3 e5 5.dxe5 would attack the Black knight on f6. 4.f3 This is the Blackmar-Diemer Gambit (BDG).

All the games in this book reach this BDG starting position or transpose later to BDG positions from a wide variety of move orders. 4Bf5 Most of this book covers the Accepted lines after 4exf3. This chapter covers BDG Declined lines (mostly 4Bf5). This 4Bf5 is called the Vienna Defence. Black hopes to keep an extra pawn, but White has ample compensation. 5.fxe4 This 5.fxe4 was Diemers favorite and mine too.

Now and then I try 5.g4 Bg6 6.g5 or 6.h4, but rarely 5.Bc4 or 5.Bg5. 5Bxe4 Black gives up a bishop for a knight but keeps the pawn. 6.Nxe4 Nxe4 Next, White usually attacks the unguarded knight in the center of the board with 7.Bd3, although 7.Nf3 is playable. 7.Bd3 Qxd4 My opponent grabs a second gambit pawn and protects the knight. But who is protecting the queen? Black falls for this trap which can occur in many Blackmar-Diemer lines. 8.Bb5+ This bishop checks while the White queen attacks the Black queen.

There is no defense to save her majesty. 8c6 Or 8...Nc6 and 9.Qxd4 wins since the c6 knight is pinned. 9.Qxd4 cxb5 10.Qxe4 Black takes the bishop while White takes the knight. 10Nc6 11.Nf3 000 12.00 e6 Black has lost the queen but plays on. White's strategy is to complete development and go after his opponent's king. 15.Rxd1 f5 16.Qxe6+ Kb8 17.Bb6 White closes in for mate by cutting off both a7 and c7, but I missed a forced mate with 17.Qe8+ Kc7 18.Rd7 mate. 17...Nb4 18.Rd8# 10 Black is checkmated

Game 2 [4.f3 Bf5 5.fxe4 Bxe4]

1.d4 d5 2.e4 dxe4 3.Nc3 Nf6 4.f3 Bf5 5.fxe4 Bxe4 6.Nxe4 Nxe4 7.Bd3 Qd5 Black's queen defended the e4 knight, but stops short of taking on d4. 17...Nb4 18.Rd8# 10 Black is checkmated

Game 2 [4.f3 Bf5 5.fxe4 Bxe4]

1.d4 d5 2.e4 dxe4 3.Nc3 Nf6 4.f3 Bf5 5.fxe4 Bxe4 6.Nxe4 Nxe4 7.Bd3 Qd5 Black's queen defended the e4 knight, but stops short of taking on d4.

Now White has time to develop and castle. 8.Nf3 e6 9.00 Nf6 10.Qe2 10Be7 Or 10...Nc6 11.c3 Qh5 12.b4 with chances for both sides. 11.c4 Qd7 12.Bg5 Nc6 13.d5 Whites king has safely castled. Blacks king has not. Now it is time to open the position and attack any weaknesses. 14.Bxf6 Better is 14.cxd5 with chances for both sides. 14gxf6 15.cxd5 Qxd5 16.Bc4 Qc5+ 17.Kh1
