Spotted over on StreetFighter4.us that they rounded up several videos of Korean champion Poongko. This guy is hands down one of the best SF4 players, and while he normally plays Ryu, there's a few clips of him using other characters as well.
In the video above, which lacks sound, you can see him consistently pull off Fuerte's infinite loop combo. Here's some other clips.
He will be representing Korea in the SFIV National Championship this Saturday in San Francisco, going up against the American champion and two Japanese players, Daigo Umehara and Iyo.
Poongko plays a very aggressive style with exceptional execution skills, and considering the level of talent the other players have — this tournament should be outstanding.
