Moves 1.d4 d5 2.c4 Nc6
ECO D07
Named after Mikhail Chigorin
Parent Queen's Gambit

The Chigorin Defense is a chess opening named for 19th century Russian grandmaster Mikhail Chigorin. An uncommonly played defense to the Queen's Gambit, it begins with the moves:



1. d4 d5

2. c4 Nc6


The Chigorin Defense violates several classical principles: Black does not maintain the center pawn at d5, the c-pawn is blocked, and Black must be willing to trade a bishop for a knight. In return Black gets quick development and piece pressure on the center.


Although opening assessments change as improvements are found for each side, the Chigorin is generally considered playable for Black and it is useful as a surprise weapon against the Queen's Gambit. Alexander Morozevich is perhaps the only modern grandmaster who regularly plays the Chigorin Defense, although in the 1980s, Vasily Smyslov did employ the opening against Garry Kasparov. Morozevich has also published a book on the Chigorin Defence,[1] in which he gives both a theoretical and a personal view on the opening.

3.cxd5 Qxd5 4.e3 e5 5.Nc3 Bb4 6.Bd2 Bxc3





  • 3...Bg4 4.cxd5 Bxf3 (see first diagram)

    • 5.gxf3 Qxd5 6.e3 and now Black has two very different, but proven ways of playing 6...e5 7.Nc3 Bb4 and 6...e6 7.Nc3 Qh5.

    • 5.dxc6 Bxc6 6.Nc3 and Black has now two well established options 6...Nf6 and 6...e6.



  • 3...e6 is fine.



3.cxd5 Qxd5



  • 4.e3 e5 5.Nc3 Bb4 6.Bd2 Bxc3 (see second diagram)

    • 7.bxc3 and now black's main moves are 7...Nf6 and 7...Qd6.

    • 7.Bxc3 has received considerable attention in recent years and 7...exd4 8.Ne2 Nf6 9.Nxd4 0-0 seems to be considered Black's most reliable choice, but the sharper 8...Bg4 is also sometimes played.
