Tactics

Tactics can have the following meanings:

1. The reading of move sequences, their variations and related decision making, and the related skills.
2. The techniques used in (often local) fights and the skills you need to bring them to a good end.

If the first meaning is used tightly as 'reasonably complete tactical reading', 'tactics' is the complement of strategy. The second meaning is usually known under the name 'techniques'.

Tactical skills

• Reading ability
• Tesuji
• Knowledge of life and death
• Good instincts
• Shape

A local move with a large benefit is called a strong move.

Strategy

The planning and decision-making based on incomplete information about the details of variations and related decision-making, and the skills for thinking globally are called strategy.
