p.34 In war, topography dictates the operations.

p.42 Unless you analyse the position you will achieve nothing.

p.45 a dynamic or interior analysis... In this analysis your primary object is to see whether your pieces have a future, whether from where they stand they can occupy stronger squares or seize, or control, important files or diagonals. Although apparently strongly placed, a piece may yet have no future where it is, since there is no way for it to occupy, if need be, other perhaps more important points, or to co-operate effectively with your other pieces... If all is not well in your camp, if one or more of your pieces have no "future," or if between your pieces there is no proper liaison, your course is obvious: put your house in order while there is yet time.

p.45 Do not leave any piece where it has no range of action or is out of touch with your other pieces.

p.82 Do not leave your pieces in bad positions... If you have a piece badly placed, or whose range of action is restricted, make it your first business to provide him with a better position.

p.83 We can gain nothing in Chess except by means of threats. Now threats may be of various kinds: direct or indirect, real or merely apparent, etc. They may also be immediate or remote, and it is here that the greatest difference in threats lies. Against an immediate direct threat, it is not in general difficult to find a parry to it, given that the forces on each side are equal. Against a remote threat, you will only succeed in finding a good defence if you foresee it coming many moves ahead, as many moves in fact as your opponent planned it.

p.90 Chess is indeed a struggle between two minds, not a matter of chance, certainly not a mere haphazard moving of pieces
