Think of the engine like a clockwork. Every gear is a piece of code: move generator, evaluation, search. The key is to keep each gear tight – generate moves with bitboards, evaluate with precomputed tables, prune with alpha‑beta and iterative deepening. Use a transposition table to avoid re‑spinning the same state. Keep the cycle short so the engine runs smooth, like gears meshing without wobble. A quiet, precise engine never needs a lot of noise.
