It's kind of a fun addition for duolingo users.

They speak Chess in the Check Republic.

King - Moves one square in any direction. Queen - Moves any number of squares diagonally, horizontally, or vertically. Rook - Moves any number of squares horizontally or vertically. Bishop - Moves any number of squares diagonally. Knight - Moves in an ‘L-shape,’ two squares in a straight direction, and then one square perpendicular to that. Pawn - Moves one square forward, but on its first move, it can move two squares forward. It captures diagonally one square forward.

The chess pieces are what you move on a chessboard when playing a game of chess. There are six different types of chess pieces. Each side starts with 16 pieces:

eight pawns two bishops two knights two rooks one queen and one king

Chess is a two-player abstract strategy board game where players take turns moving pieces on a checkered board, attempting to checkmate the opponent's king. The goal is to capture the opponent's king by placing it in a position where it is under attack (check) and cannot escape capture.
