" GM Seirawan posits to be the four primary principles which must be considered when objectively evaluating a chess position – Force, Time, Space and Pawn Structure. "
No one consciously uses these concepts when evaluating a position any more that they use Steinitz's 9 or 10 elements for evaluating a position. Why saddle players with these outdated and impractical concepts?
.
I consciously think about these principles while playing. However, I find Dan Heisman’s seven elements more useful and think about them more often: mobility, flexibility, center control, piece coordination, vulnerability, time, and speed.
These are not outdated concepts, and they never will be. They are not the ONLY concepts, just considered to be the PRIMARY concepts.
