Tarek, thanks for a nice Samurai for a lazy post Christmas and pre New Year's Eve evening.
Solving this puzzle went too smooth and fast.

Only Intersections, N/H-Singles and some Naked Pairs, Triplets and Quads in adjecant cells ??
Could I have done an error that was "correct"?

Solving the puzzle with JSudoku confirmed my suspicion. JSudoku says that the puzzle needs an X-Wing, which I did not need. Going through the log revealed that I had seen an incorrect Naked Triplet {245} in g5:r6c789 -> g5:r6c5 <> 4 + g5:r6c2 <> 5. :drunk: :whistle: :cheesey:

To solve this puzzle correctly I needed Intersections, N/H-Singles, one Naked Quadruplet and one X-Wing.
