Chess Wiki
This is a list of questions to ask beginning chess players, to see how well they understand the basics of chess, such as piece identification, piece movement, piece initial placement, protection, endgame strategies, et cetera. Answers will seem quite obvious to experienced players, but remember, everyone was new to the game once! Feel free to add questions and renumber them.

Q: What is en passant?
