[October 05, 2016] Updated Opening Line by Borki Predojević:
Catalan Defense, Closed Variation; Bogo-Indian/Catalan Hybrid

[Line 230 : 1. d4 Nf6 2. c4 e6 3. Nf3 d5 4. g3 without 4… dxc4, 4… Be7]

Line 230 deals with introductory lines of the Catalan Defense, whereas the variation with 4… dxc4 can be found in Lines 239-242 and 4… Be7 in Lines 235-238.

Another Black’s frequent choice is 4… Bb4+, where besides the most common reply 5. Bd2, White has at his disposal an interesting gambit line starting with 5. Nc3.

Variation arising after 4… Bb4+ 5. Bd2 Be7 is also very popular, and is covered in our Lines 231-234.

Sideline 4… Bb4+ 5. Bd2 Bd6 is also a solid alternative, which we recommend to club level players.

In the main focus of this opening line is 4… Bb4+ 5. Bd2 Bxd2+, where White has two responses: 6. Qxd2 and 6. Nbxd2. After trading the dark-squared Bishops, White has somewhat better development, but Black has good chances to maintain the balance.

[Diagram: White to Move] Though Black’s position is without obvious weaknesses, his King is poorly protected, which allows White to obtain a strong attack. How should he continue?
