Her exposure to the game has been more literary than competitive, picked up in the margins of a publishing life rather than through serious study, so while she grasps basic principles like development and king safety, her middlegames wander and her endings often slip. With the white pieces she gravitates toward the quiet, system-based [Colle System](/resources/openings/colle-system), a setup that suits a player who would rather follow a familiar shape than memorize sharp theory. As Black she answers 1. e4 with the symmetrical [Petrov Defense](/resources/openings/petrov-defense), trusting structure over fireworks.
