Jiri Orsag training

Here is a training clip of Czech lifter Jiri Orsag. 220kg for two cleans and one jerk.

I really wonder how to write his name (don't even talk about spelling?). In the video title it says Jiri Orsag but the channel is named Jirka Orsag. Or is that not his channel? Anyhow here is the video (I bet no one ever reads until here ;)).
