of this variation} 6. ... Qa5 {The Cambridge-Springs system was introduced
in practice by the American grandmaster H. Pillsbury. It is characterized 
by the black queen's development to a5, from where it exerts pressure 
along the a5-e1 diagonal, which may be supported by the black bishop lunge
Bf8-b4 together with the Nf6-e4 maneuver, and also operates on the fifth 
rank acting against the white g5-bishop. 
These tactical opportunities for Black force White to the continuation} 7.

In such  impregnable  positions White experience difficulties with finding
a precise plan. After White fixes his spatial advantage by preventing the 
opponent s liberating moves, he has to patiently look for tactical nuances
for starting the combat. As a rule, these nuances arise in process of 
multiple regrouping of the sides, which respond to some threats, the real 
ones as well as imaginary ones, which occur all over the board. This game 
perfectly illustrates such strategy. } 14. b4 Rfc8 15. Qb3 Qd8 16. Rfd1
