## Grünfeld Defense: 3 quick facts

- Named after Austrian player [Ernst Grünfeld](https://en.wikipedia.org/wiki/Ernst_Gr%C3%BCnfeld?ref=blog.duolingo.com), this opening appeared by [transposition](https://blog.duolingo.com/popular-chess-openings/#transposition) in the famous [Game of the Century](https://en.wikipedia.org/wiki/Game_of_the_Century_(chess)?ref=blog.duolingo.com), played by [Donald Byrne](https://en.wikipedia.org/wiki/Donald_Byrne?ref=blog.duolingo.com) and [Bobby Fischer](https://en.wikipedia.org/wiki/Bobby_Fischer?ref=blog.duolingo.com). It gained international recognition in the 1900s, and has since been played by top [grandmasters](https://blog.duolingo.com/how-to-become-a-chess-grandmaster/).
- The Grünfeld Defense is an extremely [sharp](https://blog.duolingo.com/popular-chess-openings/#sharp), [attacking](https://blog.duolingo.com/popular-chess-openings/#attacking), [hypermodern](https://blog.duolingo.com/popular-chess-openings/#hypermodern) opening for Black against [1. d4](https://blog.duolingo.com/popular-chess-openings/#d4). Black allows White to gain a space advantage and build [a strong pawn center](https://blog.duolingo.com/chess-opening-moves-tips/#tip-2-control-the-center), then tries to break it down.
- Because the Grünfeld is highly [theoretical](https://blog.duolingo.com/popular-chess-openings/#theory) and often leads to [imbalanced](https://blog.duolingo.com/popular-chess-openings/#imbalanced) positions, it’s generally recommended for advanced players. If not properly prepared, things can go downhill fast for Black!
