What I am trying to teach with this theme is that the wave goes down as well as up. After the position changes, the conditions for our forces will have changed again, and it is often time to build up (evolution) a bit more before making further revolutions. It is an understanding ofhow a short regrouping can be vital for any attack being successful; even ifwe have invested a pawn, piece, rook, queen, or army in the attack. 'Don't panic!' is the short version, because this is all about psychology.
