Chess Strategy
Two guides worth reading: one on the tactics your opponents are already using against you, and one on opening systems that give you a plan from move one.
Chess improvement is mostly pattern recognition. Learn the tactical patterns that decide games, then learn the opening plans that let you reach positions you understand. The guides below cover both.

Chess Opening Strategy
Three systems worth knowing: the London System for White, the Caro-Kann Defense against 1.e4, and the Sicilian traps that punish careless play. Plans, not just moves.
