Can White still save this game? Try to find the right moves to salvage a draw. Good luck everyone. Answer will be on April 19, 2014.

Oops! Forgot to say that it\'s White to move. Sorry about that.-

2Canada  cc14226285672014-04-17 09:16:00
am thinking that
1.Kc8+ Kc2
2.Rb7 f1=Q
3.? is the correct path
need more time

I see the idea, keep checking the king with the rook on the 7th rank and the black king will be forced up the board. A6 looks a safe square for him though and force white to allow a non check move, then the black queen and rook will come into play.
If, instead, 1.Ka8 then c6 becomes the black king escape square.
1.Kc6+...
2.Rb5...
but all blacks rook moves need to be worked out. I need more time as well.

it becomes obvious that white must keep checking or lose.Therefore the black king will head for the rook trying to escape checks-

5Canada  cc14226285672014-04-18 12:47:14
I get something like this.
1.Kc8+ Kc2
2.Rb7 f1=Q
3.Rc7+ Kd3
4.Rd7+ Ke4
5.Re7+ Kd5
6.Rd7+ Ke6
7.Re7+ and black has to go back to d5 because
7...Kf6 8.Re1+ Kg6 9.Rxf1 Rxf1 is a draw.


black can also go the other way.Like this
1.Kc8+ Kc2
2.Rb7 f1=Q
3.Rc7+ Kb3
4.Rb7+ Kc4
5.Rc7+ Kb5
6.Rb7+ Ka6
7.Rb6+ Ka5
8.Rb1+ Ka4
9.Rxf1 draw

Now It becomes clear why the puzzle has a bishop.It becomes necessary in the end.-

Well done windmill. It\'s not an easy puzzle but you got the solution right! Sorry for the delay in confirming your solution.

As per Windmill\'s second line, if the black king tries going the other way, you get this.
