http://www.dota2.com/watch/76561198198486997 but the line is not stable. I'm not able to watch the game smoothly because I didn't download Dota 2 in my laptop. Then I watch the game at http://www.dota2.com/international/live/ and they're using Youtube to stream as below.
Overall it is a great experience to watch it live although it has been a long time I didn't play Dota 2. Anyways, just wish good luck to Mushi and his team as below.
