Typical Dolgo performance - very nice attempts of fabulicous play at times, but failing on whatever a big point. Jack Reader should explain to him the meaning of the words 'patience' and 'safety play'. It's apparently lost on him.
That said, it also makes up for the attraction. Better luck next time Dolgo. 4rth round, not bad at all, and losing to Rafa is never a shame.
As for Rafa... difficult to judge on where he stands right now, still. He didn't have to do all that much, just wait for the opponent to implode. Still I maintain my opinion that he's the major favourite for the title here. Well done, Rafa. Keep it going.
