Hi all,

Okay, here is my best guess to Michael's puzzle.
Very good puzzle Michael, feel free to give us another one sometime.
How is this Michael?

1. Ka3  Ra4+
2. Kb2  Ra2+
3. Kc1  Ra1+
4. Kd2  Ra2+
5. Ke1  Ra1+
6. Kf2  Ra2+
7. Kg3  Rg2+
8. Kf4  Rxg4+
9. Ke5  Rg5+
10. Kd4  Rg4+
11. Kc5  Rg5+
12. Kb4  Rg4+
13. Ka3  Ra4+
14. Rxa4++

How I came to my conclusion.
From what I can tell, to avoid stalemate, you must take the black rook and put black in check at the same time. 
There is only three squares you can move to one time to put black in check.
Queen to a5
Queen or Rook to h8
Rook to a4, only after pawn on g4 is taken.
So what I looked at is how to move the white king so the black rook would be forced to land on one of these squares in order to keep the white king in check. 
Not an easy task, but I hope my solution above meets Michaels approval.

Chris

hi Alvin,

that would be a draw, there is a way for white to checkmate black.

of course the problem is for white to stay out of check of black's rook.

black's rook can never be taken because then it would be stalemate since
black has no other moves.

for those of you who want to give the chess puzzle a try, it is below.

thanx to Jorge Mendoza, a nice fellow  living in Spain, who gave me this
puzzle.

hi folks !!,

here is a chess puzzle for you.

in algebraic notation.

white: Rh4, Kb4, Qc3, Bb3, Nd3, B e3, Nf3, Pg4, Pb6, Pc7.

Black: Ka8, Pb7, Rf4+.
white to win by checkmating black, in an unspecified number of moves.

right now, black's rook on f4 is checking white's king on b4.

good luck.

mike A.

and my second answer is:
1. Kb5 Rb4+
2. Ka5 Ra4+
3. Kb5 Rb4+
4. Ka5 Ra4+
5. Kb5 Ra5+ Black avoids losing by the 3 moves repeated rule.
6. Qxa5++
Yes or no?
