Mark Allen beat ex Reanne Evans in their bitter snooker match after the latter ignored the offer of a pre-match fist bump.
In the lead up to the clash, Allen put his fist out but this was ignored as the crowd roared.
Then after it finished, the duo didn't so much as look at each other as Evans left the arena following a dramatic event covered live by Daily Star Sport.
The lead-up was dominated by the fallout between the pair.
In an interview after the clash, Allen described facing his ex-partner as "awful".
In the end, Allen won the contest by three frames to two, but Evans put up a brilliant fight and came close to snatching victory.
Allen goes through to round two after the match that was clearly loved by those in attendance.
Before the match, Evans had said: "To be honest up until now it's been quite easy, I've got a good support group around me and they've made me focus on myself mainly and what I've got to do, like the whole two seasons and that's what I've got to do.
"It's just like playing any other player, top player, obviously you don't want to play top players first but it is what it is, it's snooker and we're all in the same sport.
"I'm just happy to have had two years on tour and to have been able to enjoy it.
"I don't know what I'm going to feel when I'm out there but I've sort of levelled myself out trying to expect what I'm going to expect.
"The crowd as well, we haven't had that for so long. I'm just looking forward to it."
