Ronnie O'Sullivan made a record 12th competitive 147 break to complete a 9-3 win over Ding Junhui in the Welsh Open final.
The Chigwell cueman led 7-1 after a one-sided opening session and, after Ding hit back with consecutive centuries, he pulled away again.
O'Sullivan rounded the match off in the ultimate style with a maximum, playing to the crowd as he switched to his left hand to sink the final black.
A kick on the final blue threatened to derail the maximum but the five-time world champion potted a good pink and finished the job.
Asked when the 147 entered his thoughts, O'Sullivan told BBC Wales: "I think it was on about 48 when I went into reds, they split nicely and I looked at the scoreboard and saw it was all blacks.
"I thought 'no, just get the match won', but on about 60 or 70 I thought 'I've got to go for it'."
Regarding the swift change of hands before the final ball, he added: "I've made 11 (maximums) right-handed... that counts as a left-handed 147 because if I missed that, it wouldn't have counted!"
