Indian challenge ends

But India number two shah hit back with a fine 64 in the fourth to which the 43-year-old Seng replied with a 54 before allowing the Indian cueist to have a chance to clear all the colours by muffing the yellow.

Shah cleared from yellow to the pink to restore parity at 2-2 before Seng took control of the proceedings but not before he made good a 15-point 35-50 leeway in the sixth in spectacular style when leading 3-2.

Seng came up with a long blue pot and brought his cue ball off four cushions close to the pink nestled along the top cushion which decided not only the frame but also the match as his Indian rival never recovered after this.

Seng is to meet Marlon Manalo of The Phillipines, a former Asian champion, while the other semi-final will pit Pakistan8217;s former world amateur runner-up Saleh Mohammed against Thai Nappadon Sangnil.

Mohammed thrashed Hung Ching-Ming of Chinese Taipei 5-1 in another quarter-final clash.
