Hull FC have won their last five Challenge Cup semi-finals.
Just going to leave that there.
Just in case.
Warrington 16-14 Hull FC
Warrington and Hull fans won't need reminding of the 2016 final between these teams - that was a similarly tight affair which Hull won with a late Jamie Shaul try.
The Wolves have got about 10 minutes left to hold onto this two-point lead.

Wow. What a moment this could prove to be.
Accidental offside as the ball bounces amongst two Hull bodies into the arms of Josh Griffin after a perfect up and under. He immediately feeds the onrushing Jamie Shaul who slides under the sticks to the sound of Robert Hicks' whistle.
The finest of margins often decide semi-finals.
Warrington can breathe.

Taylor wasn't going to be stopped - he just drove and drove and got himself over the line.
Does that wobble the Wire?
Scott Taylor, goal Marc Sneyd
Hull needed a bit of luck and they got it.
They were handed a repeat set after spilling the ball on the Warrington line and seeing Brad Fash win the resulting grapple on the floor with Wire skipper Chris Hill, who touched the ball when loose.
A couple of battering rams later and Scott Taylor forced his way over the top of Stefan Ratchford through pure brute force.
Marc Sneyd adds the extras and this is GAME ON!

If you are a Hull fan, you're thinking we're in a desperate situation, but just one piece of magic will lift everything and the momentum will change, but they need to get it to their best players.
At the moment Warrington don't need to change anything, their game plan is working, they are eight points in front and they can close the game off.
Warrington 16-8 Hull FC
A repeat set for Hull after Mark Minichello had the ball knocked out of his hands on halfway gave the Black and Whites a glimpse of the Warrington line. Albert Kelly danced and darted to squeeze out some space and then turned kicker.
Looking at the replay, I think it was pretty much perfect for Ratu Naulago but the big winger misjudged it in flight and couldn't gather.
That was a better chance than it looked live.

With about 20 minutes to play in Bolton, it's looking more and more likely that Chris Hill will be leading Warrington out at Wembley on 24 August.
Don't count Hull out yet, though.
There was obstruction in the build-up and we don't even get to look at the grounding. Blow to Hull that. A real blow. Wire survive.
Hull wing Bureta Faraimo has gone over in the corner and Robert Hicks has said "try" as his on-field decision.

It's still raining in Bolton with no signs of it stopping, which could be why the match is being played a little slower at the start of this second half. It takes extra energy and concentration to perform in these conditions.
But the rain isn't bothering either sets of fans with many of them wearing only their team's shirt and shorts. They're proper rugby league supporters.
Nevertheless, the Warrington fans may feel warmer than their counterparts after celebrating the first try of a tense second half.

The whole atmosphere has changed. Since that try Warrington are playing on rocket fuel, pushing Hull back. Lee Radford's side are hands on knees, bent double, feeling the pace.
It's amazing what a score can do to the mind and body.
Hull just need to stay in this match. There is a lot of rugby left to be played here.

That's the one thing Toby King does well, he is very good in the air and he's brilliant at judging those crossfield kicks.
But again nobody in the Hull defence committed to the ball, they've had two tries now where no one has committed to that ball, it's a semi-final you've got to be desperate for that ball.

John James: Is it me or did it look like Warrington missed the conversion just then?
Certainly looked very close on the TV pictures! The touch judges were happy enough, though, and their flags went up.
Toby King, goal Stefan Ratchford
I'm really not a clairvoyant, you could just feel this coming. The pressure of the match was cranking up so much that something had to give.
Talking of pressure, Hull's defence didn't put any whatsoever on Warrington half Blake Austin and he was able to kick for free. Up and under it went and Toby King easily out-jumped the defenders to score.
Stefan Ratchford makes a difficult goal and the gap is now two scores.

This is really tense. I actually feel nervous, which I know is weird.
Something has to happen soon.
Warrington 10-8 Hull FC
Jason Clark just left one on Hull scrum-half Marc Sneyd to basically say "you're not going to have all day to set yourself for kicks this half, pal".
It was well within the rules though, not a late hit by any means. It'll be fascinating to see whether Warrington continue with that policy though.
Warrington 10-8 Hull FC
I'm sure it'll ignite but it's been a much slower start to this half, both sides feeling their way in to it. Exchanging kicks, completing sets, but nothing has really happened.
It's a lot more measured, I have to say.
Warrington 10-8 Hull FC
It's been a brilliant contest so far, the second half's under way. Fingers crossed for more of the same.

We've got an absorbing intense contest, there's no doubt about that. In rugby league there are different ways you can apply pressure.
You can do so by doing the basics really well and that's what Warrington have been doing, or you can apply pressure by moving the ball around and that's what Hull have been doing.
