At the DreamHack Hearthstone tournament, Radu Dima won 3-0 in the final round and was rewarded with a $10,000 check. However, during the second game Dima received a message on Battle.net revealing the details of his opponent's hand. Dima reported the message after the match, and the officials declared that the information would not have helped him and said that he could keep playing. But this prompted viewers to go back to look at earlier Battle.net messages that some are saying contain coded hints about opponents' cards.
The organizers of the tournament have yet to comment on the situation. Dima declared on Reddit this morning that he won fair and square.
