user5784: I am confused about the result of the Grenke Chess Classics 2015.
At the one hand, Magnus Carlsen won 3 games and Arkadij Naiditsch only 2, so due to
 the tiebreaker-rule, Carlsen should have won the tournament.
But then I noticed that 5 tie break games were added.
What is true and who won the tournament ?

user4362: Carlsen won the tie-break (and the tournament). 
Quite dramatically, after trading wins in the rapid and draws in the blitz games, with a win in the armageddon game.
The tie-break rules were only used to sort out the places apart from the first place.
