Teaching experience
I've coached chess for 7+ years, both online and in person, working with motivated beginners through 2000+ USCF / FIDE tournament players.
I don't use a rigid, one-size-fits-all curriculum. Usually, we begin with your own games and identify the recurring decisions holding you back—whether that is candidate-move discipline, playing too fast, missing opponent counterplay, opening transitions, or endgame conversion.
My goal is not only to help you find stronger moves during our lessons, but to build an independent thinking process you can trust over the board under tournament pressure.

Other experiences
Beyond coaching, I've collaborated with LearningChess.net and the FIDE Chess in Education Commission, translating and adapting official chess education materials into Spanish.
I also create educational videos on my YouTube channel (@EmmaChessVideos), focused on practical tournament decisions and thought process.

Teaching methodology
A large part of my coaching is built around better questions. Instead of immediately telling you what you should have played, we explore what you noticed, which candidate moves you considered, and what resources from your opponent went unseen.
Depending on your current needs, our work covers:
- Deep analysis of critical moments from your tournament or rapid games
- Calculation, visualization, and forcing-move checks
- Practical opening plans and typical pawn structures
- Middlegame strategy, endgames, and practical clock management
Between lessons, we keep the training connected without overwhelming your schedule: key positions from our sessions, opening notes, or selected exercises are organized in a shared Study with one clear priority to apply in your next games.
