Caro-Kann Defense: Panov Attack

The Panov Attack (1.e4 c6 2.d4 d5 3.exd5 cxd5 4.c4), or Panov–Botvinnik Attack, is the alternative to the quiet main line 4.Bd3 after the exchange on d5 in the Caro-Kann Defense. It is named after Vasily Panov and world champion Mikhail Botvinnik.

The idea

The Panov usually leads to positions with an isolated queen's pawn on d4. In return for that long-term weakness White gets rapid development, a grip on the e5-square and attacking chances on the kingside. The Panov can also be reached from other openings, such as the Symmetrical English (1.c4 c5 2.e3 Nf6 3.d4 cxd4 4.exd4 d5) and the Scandinavian (1.e4 d5 2.exd5 Nf6 3.c4 c6 4.d4 cxd5).

Main lines

• 4...Nf6 5.Nc3 e6 6.Nf3, the major line, when Black chooses between:
  • 6...Bb4, the main line in this database, often transposing to the Nimzo-Indian Defense;
  • 6...Be7, once the most common move;
  • 6...Nc6?!, considered inferior because of 7.c5!, after which White plans b4–b5 or Bb5 to take control of e5.
• 4...Nf6 5.Nc3 Nc6, the Modern Defense, for example 6.Nf3 Bg4 (Mieses Line) or 6.Bg5.
• 4...Nf6 5.Nc3 g6, the Fianchetto Defense.
• 4...Nf6 5.c5, the Gunderam Attack.

Strengths and weaknesses

Strengths

• Active piece play and kingside attacking chances for White.
• Black has to know some precise lines: 6...Nc6?! runs into 7.c5!.

Weaknesses

• The isolated d-pawn is a long-term structural weakness.

Who should play it

The Panov suits White players who like isolated-queen's-pawn positions and active piece play, and who want a sharp answer to the Caro-Kann.
