Surprising results between titled players: lost half points

If someone knows surprising results of chess games I would be interested to read. Here are some of them from Finnish championship tournament that was played last year 10th-18th June. To just keep the article shorter I mostly just added Houdini 3 evaluations of best moves and mistakes that were done.

Is there luck in chess? Or is "luck" actually skills?

Results after 9 rounds:

1. IM Mika Karttunen (2450) 7½/9

2. IM Vilka Sipilä (2390) 7

3. FM Daniel Ebeling (2417) 6½
