2. Evaluation skills help players decide when to exchange pieces, launch attacks, or play defensively.

Knowing the overall position quality guides strategic and tactical decisions.

3. Unlike calculation, which focuses on move sequences, evaluation is about understanding the overall position quality.

It complements calculation by determining which sequences are worthwhile to pursue.

4. Chess engines perform evaluations by assigning numerical scores to positions, typically in centipawns.

This quantifies who stands better and by how much.

5. Human evaluation often considers strategic concepts like weak pawns, open files, and outposts.

Players use intuition and experience to judge position strength.

6. Material count alone isn’t enough; activity and coordination of pieces can outweigh material deficits.

Position matters as much as material in chess evaluation.
