Grünfeld: 4.Bf4 Bg7
Grünfeld Defense: 4.Bf4 Bg7
Definition
The line 1. d4 Nf6 2. c4 g6 3. Nc3 d5 4. Bf4 Bg7 is a sideline of the Grünfeld Defense (ECO code D70). Instead of the mainstream 4. cxd5, 4. Nf3, or 4. g3, White immediately develops the queen’s bishop to f4, guarding the d6–c7–b8 diagonal and exerting indirect pressure on the c7–square. Black keeps to Grünfeld principles by fianchettoing the king’s bishop on g7.
Typical Ideas & Plans
- White aims to:
- Maintain the pawn on c4 for as long as possible, making …dxc4 less appealing to Black.
- Support a later e2–e4 thrust (often via e3 and Nf3) without having to recapture on d5 first.
- Keep options open for castling kingside or queenside, depending on Black’s setup.
- Black aims to:
- Challenge the center with the usual Grünfeld breaks …c5 and …dxc4.
- Exploit the fact that the bishop on f4 can become a tactical target after …c5 followed by …Qa5+.
- Rapidly castle and mobilize minor pieces, counting on dynamic counterplay rather than a static pawn center.
Strategic Significance
Although never a main line, 4. Bf4 has serious pedigree. It sidesteps reams of Grünfeld theory while forcing Black to think independently from an early stage. Because White withholds the normal cxd5, Black cannot immediately rely on the usual Grünfeld central counterplay, and must decide when—or whether—to capture on c4 or strike with …c5. For players who relish unbalanced middlegames with original pawn structures, this variation is appealing on either side of the board.
Main Continuations
- 4…Bg7 5.e3 0-0 6.Nf3 c5 7.dxc5 – A straightforward approach in which White concedes the center but gains a healthy queenside majority.
- 4…Bg7 5.Qb3 – Puts direct pressure on d5 and b7, sometimes provoking 5…dxc4 6.Qxc4.
- 4…Bg7 5.e3 0-0 6.h3 – A “waiting” system popularized by Baadur Jobava; the move h3 restricts …Ng4 ideas against the bishop.

Interesting Facts & Anecdotes
- The move 4. Bf4 first appeared in master practice in the 1950s; Pavel Keres tried it against fellow Estonian Paul Keres in training games, though the line remained obscure for decades.
- World Champion Vladimir Kramnik used 4. Bf4 as a surprise weapon in rapid play, counting on its practical sting rather than theoretical soundness.
- The modern revival is largely due to creative players like Baadur Jobava and Richard Rapport, whose unpredictable style meshes well with this offbeat bishop development.
- Because the early bishop sortie avoids blocking the f-pawn, White occasionally launches an aggressive f2–f3–g4 pawn storm if Black delays castling.
Summary
4. Bf4 Bg7 in the Grünfeld is a resourceful sideline that steers the game away from memorized theory. It offers White flexible development and surprise value, while granting Black the usual Grünfeld dynamic chances. A sound practical choice for players who enjoy fresh, unbalanced positions.
