Description
The Cambridge Springs Defense is a line of the Queen's Gambit Declined in which Black's queen jumps to a5: 1.d4 d5 2.c4 e6 3.Nc3 Nf6 4.Bg5 Nbd7 5.e3 c6 6.Nf3 Qa5. This page reaches it by the Slav move order 1.d4 d5 2.c4 c6 3.Nf3 Nf6 4.Nc3 e6 5.Bg5 Nbd7 6.e3 Qa5. Its ECO code is D52.
Origins
The first recorded use was by Emanuel Lasker in 1892. The name comes from a 1904 tournament in Cambridge Springs, Pennsylvania, where it was played several times. Alexander Alekhine beat José Raúl Capablanca with it in the 1927 World Championship, and Magnus Carlsen used it to beat Boris Gelfand in the 2013 Candidates Tournament.
The idea
The queen move breaks the pin of the f6-knight against the queen on the h4–d8 diagonal and pins White's knight on c3 against the king. Black intends ...Bb4 and perhaps ...Ne4, with pressure along the a5–e1 diagonal. If Black later takes on c4, tactics with discovered attacks on White's bishop on g5 become possible.
Main lines
- 7.Nd2 is the main reply, meeting the pressure on the diagonal. After 7...Bb4 8.Qc2 O-O there is a trap: 9.Bd3 loses a piece to 9...dxc4, threatening ...Qxg5, 10.Bxf6 cxd3 11.Qxd3 Nxf6.
- 7.cxd5 resolves the central tension. The most common continuation is 7...Nxd5 8.Qd2 Bb4 9.Rc1.
- 7.Bxf6 removes the bishop and with it any discovered attacks on it.
White can avoid the Cambridge Springs altogether by taking on d5 earlier, transposing to the Exchange Variation. Another way is 6.a3, which Capablanca played.
The numbers
On Lichess Black wins 47.7% of the 610,000 games and White 46.0%. Between 1400 and 1799 Black is well ahead, 54.4% against 41.5%. From 1800 up White catches up: 46.2% against 47.9% between 1800 and 2199, and 48.2% against 43.4% from 2200 up. In 2,998 master games over the board 51.0% were drawn, White won 32.0% and Black 17.0%.
