What 's my next move (and why) ... ?

Code: Select all
 6 - - | 1 8 7 | - 3 9
 8 - 9 | 6 3 2 | 1 - 5
 - - - | 5 9 4 | - 8 6
-------+-------+-------
 - - 7 | - 6 1 | 8 5 -
 5 - 6 | - 2 8 | - - 4
 - 8 - | 7 4 5 | 6 - -
-------+-------+-------
 - 6 - | 8 - 9 | - - -
 1 - 3 | 2 - 6 | 9 - 8
 - 9 8 | 4 - 3 | - 6 -


TIA,
JN

I don't know if you have already been able to make some eliminations but:

Have a look at column 3, you should find a naked pair which allows some eliminations there. Ditto column 8.

Then have a good look at row 5 (or box 6) to see if you can enter a candidate.
