Cambridge Springs defense. The name derives from a 1904 tournament in
Cambridge Springs, Pennsylvania in which the defense was used several times.
Practitioners of the opening have included Efim Bogoljubov, Vasily Smyslov,
and Garry Kasparov.} 7. cxd5 Nxd5 8. Rc1 {a very rare move by Kramnik} ({
the main line goes} 8. Qd2 Bb4 9. Rc1 h6 10. Bh4 c5 11. a3 Bxc3 12. bxc3 b6 (

Kramnik sacrifices a pawn, the idea is well known though this position is new}

would be good for black because the Bh4 is hanging.}) 21... Qd7 (21... Ne4) 22.

wasn't good because of} Nd5 ({but not the tempting} 23... Qd5 $2 {

protection, which is always very dangerous} Rxf5 {Shirov knows very well he
has to give some material back to reduce white's attack} (29... Rc1 30. Qg5+

difficult to play.}) 33. Ra1 Rg8 (33... Rc7 34. h3 $14) 34. Qh5+ Kf8 35. Qxh4 {
white has now enough material for the bishop and is still attacking} (35. Rd1)
