If you're not a chess player, there is still plenty to love about The Queen's Gambit. Beth's journey and storyline are riveting, but the terminology can be a little confusing at times. So, to clear things up, here are 10 important chess terms, moves, and openings from the series explained.

Castling is a special move in chess used to protect the King and put the Rook in a better position. It is also the only time a Rook can “jump over” other pieces. Castling is a basic chess term mentioned by Beth in the first episode and used frequently throughout the miniseries.

Grandmaster

A Grandmaster is the highest attainable title in chess. Vasily Borgov is a Soviet Grandmaster, World Chess Champion, and Beth’s toughest competition. Beth and her friends also often discuss the games and strategies of famous Grandmasters and the openings named after them.

The Caro-Kann Defense is an opening used by Harry Beltik when he loses to Beth in the Kentucky State Championship. Benny Watts is also shown talking negatively about the Caro-Kann the first time Beth meets him. He remarks that it is, “all pawns and no hope.” The Caro-Kann uses the moves 1. e4 c6 to combat the King's pawn opening and is somewhat similar to the Sicilian Defense.

Fork

A Fork is a chess tactic used to attack two opponent’s pieces at once. It is often played using a Knight. In the image above, the White's Knight can take either the Rook or the King in its next move. "Fork" is also the name of the fifth episode of the series.

Draw

In chess, an opponent can offer a Draw, and the game will end with neither player winning nor losing. Refusing a draw becomes an important part of Beth’s play. In her first chess tournament, an opponent offers her a draw. Townes shakes his head behind him, and she refuses. In Beth’s final match with Borgov, he too offers a draw. When Beth refuses, she goes on the win the game.
