    OK they are getting slightly more difficult now so lets start with the K in the centre where it is best placed.



    (black to move) Black wants to stay in the centre and white must force him to the edge to deliver mate. Pressure needs to be bought by both the King and Rook.

    1. ... Kd5
    Black tries to keep his King in centre as long as possible
    2. Ra4
    Restricting the Kings space
    2. ... Kc5
    On this and all subsequent moves black stays as close to the centre as he can
    3. Ke2 .. Kb5;
    Attacking the Rook[/i]
    4. Rd4 .. Kc5;
    5. Kd3 .. Kb5;
    6. Rc4 .. Kb6;
    7. Kb4 .. Kb7;
    8. Kb5 .. Ka7;
    9. Rc6 .. Kb7;
    10. Kc5 .. Ka7
    If 10. ... Kb8; 11. Kb6 .. Ka8; 12. Rc8++
    11. Rb6 .. Ka8;
    12. Kc6 .. Ka7;
    13. Kc7 .. Ka8;
    14. Ra6++

    Aploogies in advance for any typos. I haven't checked this out on a board.

    K & 2Bs vs K next

    Too bad you didn't make the best moves for either side.

    I wasn't trying to make the best moves, just showing the principles.

    Edit: and I was doing it all in my head without a chess board or piece in sight.

    ... but feel free to post better information that will help all those who ask this question.

    I understand that. But when you say that the black king should stay as long as possible in the middle, and then play 3. ... Kbc5-b5 instead of the longer-lasting 3. ... Kc5-d5 then it is a sad breach of your own principle.

    True but most beginners are likely to attack the rook

    I think it is always import to use all the pieces on the board.

    Not only the Rook can be use to restrict the King but also the King can block fields.

    Personally I would solve this like the following move order:
    1. ... Kd5
    2. Kd2 Ke4
    3. Re1+ Kd4
    4. Re3 Kc4
    5. Rd3 Kc5
    6. Kc3 Kb5
    7. Kd4 Kc6
    8. Kc4 Kb6
    9. Rd6+ Kc7
    10. Kc5 Kb7
    11. Rd7+ Kc8
    12. Kc6 Kb8
    13. Rd8+ Ka7
    14. Re8 Ka6
    15. Ra8#

    1 more move than me but that does not matter. We are talking principles here that novices can grasp not how to mate in the quickest most elegant way so it is useful for a novice to work through all the examples to see all the ways it can be done. Then they should be able to do it themselves from any position on the board.

    Thanks, DF.

    I would like to see the K + 2B vs K because I don't know how to do that yet.

    I teach five year olds how to mate with this material. They can all do it in their sleep. I would never dream of trying to get one of them to use the constricting box method.

    All you need to know to mate with a lone rook is how to properly leverage opposition with your King. Since this is also a key concept for pawn promotion in late end games it serves to solidify that knowledge. The moves required are rather trivial to figure out OTB. It is not the optimal 'least moves' mate, but it is one that anyone can do.
