Advani, who is already in the knockouts, cruised to a 4-0 win over Mike Toth from Switzerland, aided by two half-century breaks to top his group with an all-win record after six outings.
"I am happy that I topped the Group and the real tournament begins tomorrow. Given the conditions here, I am going to be a different player, so don't expect any fireworks from me. I will probably play slower than normal and will not take too many chances," said Advani after resuming play post a day's break.
"This (practicing during tournament) is something I usually avoid and so I have prepared as well as I could for this tournament," said India's poster boy of cue sports.
Other notable entries to book their knockout berths were Asian champion Thor Chuan Leong of Malaysia alongwith India's Laxman Rawat among others, who made a mark today.
