Player: kai2011 Subject: Hi from the Crimea! Foolish puzlle#3
|This is most easy task!|
White to move and seems win
To add some complexity to the task - a chess Board are not limited to 8 horizontal and vertical \"h\"! White still able to put a black Mate!! What is the minimum size of our unusual chess boards will you need? Mx34 or 23Qx487? Remember,please, His Majesty White King had injuries and He can\'t have long walks!

|There no difference who are on the move! Only the size of the board increased if it\'s black turn! At first it seems that black king moving through diagonal (Kd4, Ke5 and so on) should escape. White King should stand higher and a little right than his black opponent in order to checkmate him! This is my a bit of help. And why you have a rook?||-|

|This is silly.All chessboards are limited to 8 horizontal and 8 vertical squares.Otherwise it\'s not a chessboard.||-|

Dear windmill! How many silly things around us: your clothes, car, house, etc And it\'s all thanks to people who were not LIMITED by any borders! In my opinion it\'s much easier - you can\'t solve my task.
Break the diagonal route of black king with the aid of your rook and move white king straight along great black diagonal. When white king and rook meet each other - task is solved! Good luck!

|I\'ve never tried to solve this puzzle because it\'s not chess.It\'s silly!! There is nothing silly about my clothes,car(I don\'t have one)or my house.You may notice that no one else has tried to solve it either.||-|

No! I see that nobody solved it

Bingo! Somehow Charles Lutwidge Dodgson known as Lewis Carrol wrote two children\'s stories... in one of them was a strange chess Board... a few decades later, a man by the name of Albert Einstein, after reading this tales, created something called the Special Theory of Relativity. He did not try to appeal to the spirit of Carrol about the strangeness of his tales. He did what he was meted out by God. You try the windmill...

|wow!! I\'m sure there are many of us here anxiously awaiting Foolish puzzle #4 Thank you||-|

\"...many of us...\" Not too arrogant?

Ok I`m a mug so here goes.
Oh I give up, the black king can just keep pushing on.
|17 cc1422628553||2014-09-07 20:10:41|
When the black king gets next to the rook rhe rook goes to Z8 ?
|18 cc1422628553||2014-09-07 20:17:02|
|I cant see how you can mate the king. He needs to be up against the edge and if he can move off the edge in an infinite board when it his turn then he`ll allways escape. Yes I think a few of us would like to see this.||-|

|Dear extopian! You correctly realized that the rook moves in zigzags! Unfortunately I don\'t have much time now, on Thursday I will post the solution.||-|

White to move and seems win.
To add some complexity to the task - a chess Board are not limited to 8 horizontal and vertical \\\"h\\\"! White still able to put a black Mate!! What is the minimum size of our unusual chess boards will you need? Mx34 or 23Qx487?
This is the task. And now let me post the solution.
Here black have 2 possibilities:
1. Try to keep the white king with the help of 1. ...K b3
2. Try to escape by 1....Kd4.
Let us study both of them.
So 1....Kb3 2. Kb1 Kc3 3. Kc1 Kd3 4.Kd1 Ke3 (these moves do not require comments).
Attention!!! The rook is under attack!!!
5. Kе1 leads to a loss rate after 5. ... Ke4. If rook moves along second line the black king will continue to move away. Rook has to move along line \"f\".
But what is the 5th move for white? Maybe 5. R f6 or 5. R f33?
Here is the time to remember one of the most famous chess etudes by Richard Reti.
White to move and make draw.
The solution of this etude is: 1.Kg7 h5 2.Kf6 h4 3. e5 and it turns out that the white king manages to hold the black pawn or to protect white one.
Using the idea Reti, in the future we will move the white king on route e2,f3, g4, etc. Sooner or later, the black king again attacks the rook and we will be forced to make a horizontal move with the rook, our king should meet the rook first.
The calculation shows that the 5-th move of white should be 5. Rf9!!
Now after 5. Rf9 Ke4 6. Ke2 Ke5
7.Kf3 Ke6 8.Kg4 Ke7 9.Kh5 Ke8. The white rook is attacked again.
This is the position after 9. ... K e8 shifted by one line down.
And now it\'s easy to see that after 10.Ri9!! Kf8 11. Ki6 Kg8 12. Ki7 black king
The final position (shifted one line down and one line left).
I think now you will not be difficult to checkmate the black king. Would you like to deal with variant 1. Kd4 by yourself? Good luck!

This is final position from previous post!
