Gambix
It sees your move coming.
What it is
Gambix is a game AI that plays adversarially using minimax search with alpha-beta pruning, built from scratch. Centre-biased move ordering helps the pruning cut more branches, and a live counter shows how many positions were searched on each move. It is a from-scratch, dependency-light build - 13 tests include the guarantee that alpha-beta returns the identical move to plain minimax while visiting far fewer nodes - that you can download and run locally.
