I have written multiple articles over chess strategy and the middle game, but for some reason I have avoided writing on the endgame theme. I was scanning through the “Lazy Person’s Guide to Endgame” by GM Ian Rogers published in January 2010 Chess Life Magazine and decided to write my own thing.The first endgame analyzed by GM Rogers is the famous Queen vs. Rook ending. He claims that it is an easy win for the side with the queen. I decided to go ahead and test this Q vs. R endgame against the Chessmaster Grandmaster Edition, setting the Queen for myself and a Rook for the engine. After about 20 tries I found this task to be impossible.
In fact, according to ChessBase most GMs are not able to win against perfect defense of the computer. I used Nalimov’s Endgame Tables and concluded that it is possible to win in 30 moves if white to move or 31 move if Black to win, and if Black doesn’t win the queen.
Most guides show the way to checkmate in well known Queen vs. Rook “Key” position (shown below), but missing most important part – getting to this position. They assume it to be an easy task, when in reality it turns out to be extremely complicated against the perfect defense.
The most difficult thing for a human mind to overcome in this sort of endgame is so-called “third rank defense”. In this defense weaker side places its rook on the third rank and not allowing opponent’s king to penetrate:
According to the Nalimov’s Tables there is a win in 19 in this position.
1. Qf4 Kd7 2. Qa4+ Kc7 3.Qa7+ Rb7 4.Qc5+ Kb8 5.Kd6 Rg7 6.Qd5 Rg6+ 7.Kd7 Rb6 8.Qe4 Rb3 9.Qe5+ Ka7 10.Qc5+ Kb8 11.Kc6 Rb7 12.Qa5 Rb1 13.Qe5+ Ka7 14.Qd4+ Ka8 15.Qh8+ Ka7 16.Qh7+ winning the rook and the game

How to practice this endgame?
You can play this endgame by setting up your favorite chess engine to play for weaker side and try to checkmate it in 50 moves. It is also a great exercise which improves overall visualization of a chess board and especially the coordination of Rook and King and Queen and King.
