Translation of "Resumia" in English

Aquele final se resumia ao confronto entre um bispo bom, isto é, que dispunha de boas casas sobre as quais atuar, e um bispo mau, quer dizer, que tinha sua área de ação restringida por seus próprios peões.

That endgame boiled down to the confrontation between a good bishop, that is one who had good squares to move on, and a bad bishop, that is one who had his movement options restricted by its own pawns.
