Dr. Alexey Root individually tested beginners on the king and two rooks checkmate. While she was testing, students practiced that checkmate. Since about half of them successfully tested, she showed the king and queen versus king mate to them at the end of their 20 minutes. Dr. Root individually tested the intermediate students on the king and queen versus king checkmate and the advanced students on the king and rook versus king checkmate.
