Mark Williams claimed back-to-back wins over Judd Trump and Robert Milkins to reach the semi-finals of the Indian Open in Mumbai.
The Welshman, 39, defeated Trump 4-3 before an easier 4-1 success over Milkins to set up a meeting with compatriot Michael White.
White reached his first ranking event semi-final with a 4-2 win over Chris Wakelin.
The other semi-final sees Ricky Walden against Thailand's Thepchaiya Un-Nooh.
Walden had little trouble beating Tian Pengfei 4-0 and Joe Perry 4-2 after knocking out home hope Aditya Mehta earlier in the week.
Un-Nooh, the world number 61, shocked Mark Davis 4-2 after the Englishman had earlier defeated John Higgins 4-0.
"I'm very happy. It was really tough because Mark is a very strong safety player. I just had to fight. This has been good experience for me," he said.
"I'm not thinking about the money, I'm thinking about my ranking because I need to get into the top 48. I am on my own here because the other Thai players have gone, but I am getting a lot of messages from friends."
