[January 09, 2019] Updated Opening Line by Trajko Nedev:
Gruenfeld Defense, Three Knights Variation (incl. Hungarian Attack & Burille Variation)

[Line 146 : 1. d4 Nf6 2. c4 g6 3. Nc3 d5 4. Nf3]

After the exclusively played 4… Bg7 White has a choice of many setups, among which 5. Qb3 is covered in our Lines 148 & 149, while 5. Bg5 belongs to Line 147.

Hungarian Attack (5. Bf4) is the main option in this opening line. The game often follows 5… O-O 6. Rc1, where 6… c5 is a reasonable alternative to a more common 6… dxc4. Against the latter option, move 7. e3 leads to quiet positions, while 7. e4 can easily get a forced character.

Burille Variation (5. e3) is a modest and solid option, thus we recommend it for club level players and also for beginners. Players of White have tried many continuations after 5… O-O, namely 6. cxd5, 6. Be2 and 6. Bd2. White’s setup, though unambitious, is a hard nut to crack.

From a number of possible sidelines, White sometimes opts for the tricky 5. Qa4+ or the aggressive 5. h4.

[Diagram: Black to Move] It seems that White has a good counterplay on the queenside, while his Knight and dark-squared Bishop are doing a good job defending the King. Still, Black has the means to get a big edge – can you see how?
