Look for naked pairs, naked triples, naked quads, etc.

In this case you have a naked triple 1,6,9 in row 6 (columns 1,4,8). True, one of these is only a 1,9 and another is only a 1,6. But collectively, these three are still a 1,6,9. That means that each of the three must be a 1, a 6, or a 9. So there can be no other 1's, 6's, or 9's in row 6.

So you can eliminate 1, 6, and 9 as candidates in columns 3,5,6,7,9 of row 6. This gives you an immediate answer in column 9, and greatly reduces the possibilities in the others. Proceed from there.
