Having trouble with this one from websoduku.com (rated "evil"):

.2.|.5.|...
..1|6..|.3.
...|9.1|.25
-----------
..8|..5|6..
9..|...|..1
..2|3..|4..
-----------
17.|5.6|...
.6.|..9|2..
...|.7.|.6.

I got as far as:

.2.|.5.|1.6
5.1|6.2|73.
7.6|9.1|825
-----------
..8|..5|6.2
9.7|26.|3.1
6.2|3..|4..
-----------
17.|526|9..
.65|..9|217
2..|17.|56.

from this point I have no idea how to continue, the clues seem to have dried up!

Please help, thanks.

Eliminate some candidates based on hidden pairs in columns 2 and 5, then take a look where 8 can go in block 5 considered with column 6. Then do the same, for 8 again, for block 8 and row 8. There are interactions between the blocks and columns/rows.
