China's Liu Song failed to enter the last 16 round after losing to Mark Boyle of Scotland at the IBSF World Snooker Championship.

Liu was beaten 5-4 by Boyle in a marathon match that lasted four hours.

Liu and Boyle exchanged leads and tied 4-all after eight frames.

Liu, however, failed to grasp a last chance and lost the decisive frame with a 40 deficit.

Twenty-two year old Liu Song triumphed in the Event Six at Pontin's last week.
