"I don't think I have beaten him before. It will have to be a good performance from me. He's a higher ranked player but I will have the crowd support to count on to get a few extra points here and there," said the 29-year-old ahead of his opening game in the tournament carrying pound sterling 300,000 in prize money.
The Indian, ranked 50th, has a new coach in Mukesh Parmar of Leicester. He had lost to King 4-5 in the first round of China Open last year and the win paved the way for his rival to reach the quarters.
"If I can get through the first match then it's a game on. In this level of snooker every match is difficult, it's all about confidence. I need to get that first win in the bag and then anything is possible. Last year I had an equally difficult first match against Peter Ebdon. I got through that and we all know what happened.

After his injury, change of base from Sheffield to London and hiring of a new coach, Mehta reached the third round of the Welsh Open in February, and feels that was a good show.
"But I still have a long way to go, especially with the new coach. I am not expecting any miracles," he added.
About his winless record in four meetings with the 40-year-old King, Mehta said the gap was closing between the two and tomorrow could be that day.
