Hi. I’ve been involved in chess engine testing since 1995. In simplistic terms human crafted engines use a hand made evaluation.

First determine the set of legal moves. Then a set of legal responses to each and so on. This grows into a problem so we trim lines that our evaluation say are losing.

Each line in the search tree returns a score. Highest score wins.

Piece values. Mobility. King safety. Pawn structure. Open or closed positions are are added to investigate each line.

Ai engines like alpha zero are completely different.
