An excellent result for RMK, I thought that Greul would be a tough match up for him but he was unable to serve the match out in the second set. Now RMK will stand a decent chance if he plays against Dima, especially given that Dima comes back from injury.
Salvor Hardin: "Violence is the last refuge of the incompetent"
So it is said that if you know your enemies and know yourself, you will not be imperiled in a hundred battles; if you do not know your enemies but do know yourself, you will win one and lose one; if you do not know your enemies nor yourself, you will be imperiled in every single battle.
This is not the first time Korolev fights back from match points down, I recall saving a *5-4 40-15 in 4th set against Seppi (RG 1st round) and he did the same thing there, rolled into a 9 games winning streak, from 3-5 down to 7-5 5-0 if my memory doesn´t fail me, looks like the kid has heart
