King and a Rook against King 

 This is the most important of the three mates seen, since the same can occur with the pieces mentioned previously. Checkmate occurs when the opposing King is on the last line of play (whether row or column), our King is in front of it and with one square separating them (opposition); and our Tower gives check. 

 The steps to achieve this are as follows: 

1.  Cut off the King. 
2.  Maintain with our King the Knight jump of the opposing King, this without impeding the mobility of the Rook and keeping it blocking its path. 
3.  When the opposing King takes the Knight jump, he must take some time with the Rook. 
4.  When both Kings are face to face, Check is offered to the opposing King. 
5.  It is important to keep in mind that the Tower is a piece that acts at a distance from the King, for this reason it is important as long as it can be kept at a distance. 

 Let's look at some examples
