The World Championship last-16 tie between John Higgins and Xiao Guodong has been full of drama. The match was tied at 8-8 after yesterday's two sessions. Xiao moved ahead 9-8 with a break of 76, but Higgins responded by taking the next two frames. The 20th frame lasted over 62 minutes, with Xiao eventually winning a hard-fought frame. Higgins then took the next two frames but missed a crucial black in the 23rd frame, allowing Xiao to stay in the tournament. The tie will resume later on Saturday. Higgins, a veteran with multiple achievements, hopes to reach the quarter-finals.
