Beating the Triangle, Tarrasch & Rare Systems

A Dynamic and Aggressive Repertoire for White
by IM Dejan Marjanovic

The Queen’s Gambit Declined remains one of the most solid and respected opening systems in chess. However, IM Dejan Marjanovic presents an ambitious and aggressive repertoire for White that challenges Black’s most popular and offbeat responses after 1.d4 d5 2.c4 e6 3.Nc3.

This course offers a complete system for White against a variety of setups, including:

• ✅ Triangle System (3…c6)
• ✅ Tarrasch Defense (3…c5)
• ✅ Bogo-Indian Style Moves (3…Bb4)
• ✅ Sidelines like (3…h6, 3…a6, 3…dxc4, and 3…f5)

Key Weapons in the Repertoire

🔹 Against the Triangle System (3…c6) – The Marshall Gambit
1.d4 d5 2.c4 e6 3.Nc3 c6 4.e4!?

The Marshall Gambit is the most principled and challenging response to the Triangle. IM Marjanovic dedicates two chapters to this sharp variation, offering new ideas and creative solutions that make Black’s position extremely difficult to handle from a practical perspective.

🔹 Beating the Trendy 3…h6

• ✔️ 4.cxd5 exd5 5.Bf4 – A solid and straightforward system (Chapter 3)
• ✔️ 4.Bf4 – A more direct approach to seize the initiative early (Chapter 4)

Both variations put Black under serious practical pressure and take them out of their comfort zone.

🔹 Cracking the Tarrasch Defense (3…c5)

• ✔️ 4…exd5 – The Classical Tarrasch (Chapter 5)
• ✔️ 4…cxd4 – The Gambit Tarrasch (Chapter 6)

IM Marjanovic presents new directions and high-impact novelties, demonstrating how White can pose fresh challenges in this historically solid defense.

🔹 Tackling 3…a6

• ✔️ 5.Nf3 – A natural and flexible move
• ✔️ 5.Qb3 – Directly targeting Black’s structure

Both choices are deeply analyzed, offering White powerful ways to seize the advantage.

🔹 Challenging 3…Bb4 Directly (Insert Diagram)

White’s best reaction is 4.a3!, transposing into favorable Nimzo-Indian structures. After 4…Bxc3 5.bxc3 Nf6 6.cxd5 exd5 7.e3, White gets a stable advantage, and IM Marjanovic explains why this structure is so unpleasant for Black to handle.

🔹 Handling 3…dxc4 and 3…f5

• ✔️ 3…dxc4 – White can easily regain the pawn while keeping the initiative.
• ✔️ 3…f5 – Black aims for a Stonewall-style setup, but Marjanovic demonstrates why this doesn’t work well for Black.
