He beat Tor 7-2. I don't see anyone else being able to beat the boss like that!
Tor is a amazing battle player which is probably more valuable skill to have but he had a long break and didn't really play for a long time so he is quite rusty when it comes to duelling, it was pretty clear that Kpu would take that match.
I'm really sad to see Kpu withdraw though, was looking forward to see him fighting in the end, he had quite quite easy road ahead all the way to the finals. I think unfortunately the final match will be much more one sided now in favor of whoever advances there from the lower half of the brackets
