Chessboard puzzles involving queens are valuable teaching examples for integer programming. We present the queens domination and peaceable queens problems in an educational format and describe our classroom experience with teaching these problems. We discuss techniques for improving efficiency, such as symmetry breaking, valid inequalities, bounds, and parameters. Funding: This work was supported by the Australian Government (RTP Scholarship).
