There is a cell that is easy to fill in row 9.
After that, look for a pair in column 2 and make some candidate eliminations.
Based on the candidates remaining in column 2, you can make some candidate eliminations to column 3.
Now fill in a cell in column 3.

Please reply if you need a more specific hint.

Hi Nicola.

1. Look at the bottom row - only one possibility.
2. Look for a hidden pair in column 2.
3. Look to eliminate candidates in box 1.

Edit: looks like I was beaten to the punch.

Scrose You were right about row 9 must have been blind. But in col 2 how do I make a pair. I have the following possibilities
962
9643
42
873
43
5
32
87632

Without giving the game away - you're looking for what I call a "hidden pair" . Click here for an explanation of hidden pairs.

Edit: Bummer - looks like my server is down momentarily, so that link may not load.

Got the hidden pair in col 2 but still stuck. Also you were right couldnt load the examples from the web but got the written explanation of hidden pairs.

Now that you've found the hidden pair, have you made some candidate eliminations in column 2? If and once you have, look at where the remaining candidate 6's are in column 2. What does this tell you about where the candidate 6's cannot be in column 3?
