There was a little bit of concentration lacking for Wu Yize in that second frame. He was so good in the first frame and it could have been 2-0. It was small fractions but they make the difference.
Wu 1-1 Wilson
A less-than-fluent frame from both Wu Yize and Kyren Wilson after multiple visits to the table but it's the Englishman who squares up the match.
Wilson's break of 27 takes him down to the colours and he pots all but the pink and the black to to seal the frame.
Steve Davis
Six-time world champion on BBC Two
What a performance. That was a superb break from Wu Yize. In the early rounds he made it look very easy and who is to say he won't breeze through to the final as well.
Wu 1-0 Wilson
Wu takes opening frame against Wilson
Wu Yize bags the first frame with a confident start.
Kyren Wilson makes a break of 20 before missing a fairly straightforward red, prompting gasps from the Ally Pally crowd.
Wu is able to take advantage as he peels off a slick break of 75 before missing the brown. He's done enough, though, as Wilson concedes.
"Wuuuuu!" cry the fans.

Seven-time world champion on BBC One
Kyren Wilson was magnificent to win his quarter-final match to reach the semis. He showed some real character and resilience against Neil Robertson.

Judd should be furious with himself. He threw that away from 3-0. I'm not sure he'll ever win as many triple crown events as he should.

The hairs on the back of my neck were standing on end when John Higgins won that. We should just savour these moments in our sport.

That is why we love snooker. Final-frame decider, then John Higgins doing what he does. Class Of 92 never fails to entertain.

The Class of '92 players are, to some degree, on borrowed time. So every time they put in a performance like John Higgins did we should celebrate it. Because it won't be forever.

That was an unbelievable performance by John Higgins in the first semi-final. He gives hope to all of us 50 something balding men across the country when our backs are against the wall!

Higgins wins decider against Trump to reach Masters final
Phew. What a thrilling semi-final that was. Never ever write off John Higgins.
If the second semi between Wu Yize and Kyren Wilson is even half as good as that it will be worth watching.
We will have live coverage of that match here, and on BBC Two, at 19:00 GMT.

1991 world champion on BBC Two
Legend is bandied around in sport far too often but John Higgins is one. He tries his leg off. 5-3 down in two matches against the world's best and he's in the final. The cue ball play in that final frame, under pressure, was superb.
He'll now be looking to be the oldest triple crown winner. He'll be ready to play tomorrow.
John Higgins on BBC Two: "He [Judd Trump] is so tough to play against. I missed a couple of reds to put myself safe and then he did what he always does which is clear up. Even at 5-3 I didn't give up. It was the same against Zhao Xintong. Who knows, maybe my name is the the trophy? You just don't know.
"I think I'm a better player now than I've ever been. You play these great champions like Judd and I've lost the last few against him. At the start of the match he should maybe have been 4-0 in front and I maybe made it too easy for him. The fourth frame was massive because 4-0 it's done, but 3-1 I had hope."
John Higgins is "asked how on earth did you just do that" and responds: "I don't know!"
John Virgo
1979 UK Championship winner on BBC Two
John Higgins with an amazing performance. To reach the final by beating the reigning world champion and then put the world number one to sword is incredible.
Judd Trump will be very disappointed and he is still to win a tournament this season but John Higgins you can see what it means to him. He was always on the back foot but he fought, fought and fought.
Trump 5-6 Higgins
An incredible fightback from John Higgins!
He pots a couple of the colours before Judd Trump concedes the contest.
The Wizard of Wishaw has done it again.
Trump 5-5 Higgins
Judd Trump bungles a safety to leave John Higgins with a red and black. The Scot duly takes them. He's on the brink of a place in the final now.
