First of all, I must admit I didn't saw the match, but this Q-Bot must played (again) the match of his life.
This is a serious case-study. A challenger player level, who raises his level in a incredible way, during GS. Last 16 for him. Now Feli would be even harder, and the spanish is clearly the favourite, but I don't know anymore. There is no limits for the polish! Congrats to him!
