For Sudoku enthusiasts

I happened to read the article: http://www.elu24.ee/170678/sudokude-lahendamine-teeb-paksuks/. I immediately thought that Ain and Tiit are living proof:D:D Half an hour later I happened to read the following news:http://www.maaleht.ee/news/tarbija/tervis/article.php?id=27474765 How can such contradictory news arise from one specific thing :D? Both news are from 2009!

One article referred to the world's hardest sudoku - will our top solvers solve it? :) http://www.maaleht.ee/news/uudised/meelelahutus/maailma-koige-raskem-sudoku-parem-ara-hakka-proovimagi.d?id=25458341

When it came to the puzzle, I tried to solve it. Is it the hardest in the world, but obviously you have to try it several times before you find the solution. Personally, I don't find it attractive when a sudoku is so difficult that you have to try it several times. Unfortunately, sometimes you have to do it in competitions - is it just me that I can't do it any other way, or is it just a bit too far?
