## CAN NOT FIND THE NEXT PLAY

Post the puzzle or solving technique that's causing you trouble and someone will help

### CAN NOT FIND THE NEXT PLAY

I am consistently able to solve the 5-star puzzles that appear on Sunday in my newspaper. However, this one is the exception. All I'm looking for is the next play and how it is located. Any help would be appreciated.

Code: Select all
`                                             6   8   3     6        5            4   9   2         9          4      5   7   1     4        1            3                  4         8          3           5  5           2            9  1                 8           3     9  6`

It is very difficult to tell exactly what the original puzzle you are trying to post might be. You should use '.' to represent empty cells instead of spaces. Otherwise the spaces between cells run together with the spaces in empty cells and it is difficult to tell what is what.

The closest I can come is perhaps:
Code: Select all
`. . . | . . . | 6 8 3. 6 . | 5 . . | 4 9 2. . 9 | . . 4 | 5 7 1------+-------+------. 4 . | 1 . . | 3 . .. . . | . 4 . | . . .. . 8 | . . 3 | . 5 .------+-------+------5 . . | 2 . . | 9 . .1 . . | . . 8 | . 3 .. 9 6 | . . . | . . .`

You have it correct, except there is a 4 in the extreme right column in the sixth block from the bottom. In addition to that 4, the only plays I have made are in the top right box (3,4,9,5,7). All other numbers were given with the puzzle.

Basically, what I am hoping you can help with is the next play and the reasoning behind it.

Thanks,

There is a naked pair in row 8, and then singles to the end.

R8C2 and R8C7 can both only contain 2 or 7, that means that together they must contain 2 and 7 (though we don't know which goes in which cell). That allows us to eliminate 2 and 7 from all cells which see both of those. That immediately results in placing a 4 in R8C3.

Thanks, very much. I understand naked pairs, but just didn't work R8C2 down to the 2 and 7. I do appreciate your help.
