Chess strategy is the purposeful attempt to gain an advantage over your opponent. Unlike tactics, chess strategy involves long-term goals, usually related to king safety, pawn structure, space, piece activity, etc. Strategy is the overarching plan or set of goals you are hoping to achieve, and changing them is a slow, arduous, but still possible process. Tactics are the specific actions or steps you undertake to accomplish that strategy.

2) pawn play;

3) exchanges;

4) prophylaxis/restriction/provocation
