When you look at the results list, it becomes very clear how big the class difference was between the two participating grandmasters on one side and everyone else on the other. They drew against each other and won the rest, which meant that they finished a whole 3.5 points ahead of the rest of the field.
They shared the victory, but if you want to be precise, GM David Gavrilescu came in first after a tiebreaker, and thus GM Vignir Vatnar Stefansson came in second. Congratulations!
