The 21-year-old former amateur star produced some breath-taking golf at the Santiburi Samui Country Club as he fired four birdies, including a 30-foot stunner on the third hole, to edge towards a surprise victory in the US$300,000 Asian Tour event with his two-day total of nine-under-par 133.
A modest and soft-spoken Poom, who helped Thailand lift the team gold medal in the Southeast Asian Games last year, said Lady Luck has been on his side as he continued to upstage many stars of the game at the Queen's Cup, which is sponsored by Bangkok Airways and Sports Authority of Thailand.
"Sometimes, I'm missing some shots but I've been lucky. Today, I got up and down six times for pars, some from the fringe," said Poom, who needed only 26 putts for the second straight day. "It was great. I had good drives and if I missed, I missed at the right places. I putted good again."
Qualifying School graduate Poom said he slept well after leading the first round ahead of many more seasoned campaigners. He vowed not to look at the leaderboard going into the weekend. "I managed to sleep nicely. When I came here this afternoon, I was still thinking of just making the cut. I don't want to think about winning.
"I just want to think about avoiding bogeys, just think of pars. Maybe tomorrow I will feel more excited. I don't feel any pressure, not yet anyway. I'm not going to look at them (the other players) too much, just play my game."
Current Order of Merit leader Anirban Lahiri of India fought back with a 68 for a 143 total to lie 10 shots behind the leader. The halfway cut was set at 146 with 68 players, including two amateurs, progressing into the weekend rounds.
It has not been a good week so far for the Australians with Cameron Smith the best of them in 24th position.
