Hi,
I think that you need only to know how to use the:
"Row on 3x3 Block interaction" technique to be able to solve it.

Please take a look and see how to apply it.

8 - - 9 - 5 - 4 -
- 2 5 - - 3 - - -
3 9 - - 6 - - - -
- - - - - 1 7 - 8
- - - 3 - 6 - - -
6 - 7 5 - - - - -
- - - - 1 - - 2 4
- - - 4 - - 8 9 -
- 4 - 8 - 9 - - 3

2 in r4c4 7 in r7c6 - Sole Candidate
6 in r7c4 2 in r8c6 - Sole Candidate
5 in r7c7 5 in r9c5 - Sole Candidate
9 in r7c1 3 in r8c5 - Sole Candidate
3 in r1c7 6 in r4c8 7 in r5c5 - Unique Horizontal
2 in r1c5 3 in r6c8 - Unique Vertical
6 not in r1c9, it is in r2c7 or r2c9 (Row on 3x3 Block interaction)
5 not in r5c1, it is in r4c1 or r4c2 (Row on 3x3 Block interaction)
5 not in r5c2, it is in r4c1 or r4c2 (Row on 3x3 Block interaction)
8 not in r6c2, it is in r5c2 or r5c3 (Row on 3x3 Block interaction)
2 not in r5c7, it is in r6c7 or r6c9 (Row on 3x3 Block interaction)
2 not in r5c9, it is in r6c7 or r6c9 (Row on 3x3 Block interaction)
1 in r6c2 - Sole Candidate
8 in r5c2 - Sole Candidate
3 in r7c2 - Sole Candidate

... for the rest,
there is not need to tell you how to continue.
(only for a "Maß Bier", a bottle of red wine, or a barell of whisky)


Final SuDoku Table

8 6 1 9 2 5 3 4 7
7 2 5 1 4 3 9 8 6
3 9 4 7 6 8 1 5 2
4 5 3 2 9 1 7 6 8
2 8 9 3 7 6 4 1 5
6 1 7 5 8 4 2 3 9
9 3 8 6 1 7 5 2 4
5 7 6 4 3 2 8 9 1
1 4 2 8 5 9 6 7 3

P.S. hope this is the one you referred, so that I did not work for nothing.

see u,
