You can spot the mexican defense when Black develops the knight to f6 and often follows with ...g6, ...Bg7, and castling, while keeping the center fluid. To use it well, focus on solid development, avoid passive play, and look for chances to undermine White's center with moves like ...c5 or ...e5 at the right moment.
