Roger Federer hit three magical winners - forehand, backhand and drop shot - during his first round match win against Philipp Kohlschreiber in Dubai. In press conference, the Swiss analyzed his upcoming second round match against Fernando Verdasco: " "I always thought it was hard to play left-handed servers because their strength goes into your weakness, your strength goes to -- I don't know. It just doesn't work properly against the lefties", said Federer. "For a one-handed backhand player, I have a great record against left-handed players. Obviously Rafa (Nadal) has caused me most problems throughout."
