The annual World Championships was unveiled at the Crucible Theatre on Saturday and the 29-years-old Robertson became the first loser in the competition.


"I made several silly mistakes," said Robertson, "but it's not really a setback. I have got six ranking titles in the past five or six years and the match today was so close all the way."


Trump, 21, came to Sheffield with a huge boost of confidence as he has just won his first ranking tournament title at China Open earlier this month. He managed to lead the first session 5-4 with two centuries, but Robertson pulled one back with 64:54 in the tenth frame.


While leading at 7-6 and 58-1, Trump missed a black ball to give Robertson chance. The Aussie then thrillingly cleared the table with a break of 58, climbing back to 7-7.


However, Trump was calm enough to take the following two frames and finally wrapped it up 10-8.


"I'm on a high at the moment and I don't want it to end. I want to make winning a habit," said the world No. 14 player.


2005 world champion Shaun Murphy is only one frame away from the second round as he leads Marcus Campbell 9-0.

Mark Williams heads Ryan Day 6-3. Ali Carter leads Dave Harold 8-1 while Andrew Pagett trails Jamie Cope 5-4.
