The evaluation parameters were manually refined rather than learned autonomously, unlike modern neural network systems.
Beyond raw calculation speed, Deep Blue relied on an evaluation function that scored board positions based on numerous weighted factors. These parameters included piece activity, pawn structure, king safety, mobility, and positional patterns derived from grandmaster knowledge. The 1997 version expanded and refined these heuristics compared to the 1996 system. Engineers and chess experts iteratively adjusted weightings through testing and analysis. The evaluation function allowed the system to prioritize promising variations within its vast search space. It represented encoded human expertise translated into machine-readable form. Performance depended not only on hardware but also on strategic modeling. Knowledge was quantified.

Technologically, the evaluation function illustrated the importance of domain expertise in early AI systems. Human grandmasters contributed conceptual understanding to algorithm design. Parameter tuning became a collaborative process between programmers and chess professionals. This hybrid model foreshadowed later machine learning pipelines combining data and expertise. AI performance was not purely emergent; it was engineered. Encoding strategy into parameters bridged intuition and computation. Expertise became algorithmic capital.
For observers, Deep Blue’s moves sometimes appeared surprisingly human. That resemblance stemmed from carefully encoded positional principles. Kasparov later remarked that certain decisions felt purposeful rather than mechanical. The machine’s strength emerged from human insight scaled computationally. Thousands of numerical weights shaped a single move choice. Strategy was transformed into mathematics. Judgment became formula.
