With top 32 players crashing out all over the place, there are only three all-seeded matches in round three this year.
And by a quirk of the scheduling, they all take place this afternoon.
Which means, naturally, that three more players will real aspirations of going deep at Ally Pally are going to be sorely disappointed.
Schindler v Searle

Ryan Searle is the slight favourite for me. In his mind he'll know he's still got a big job ahead though with him being the lower seed.
We'll know by the end of the game if either are serious contenders.
Right, let's get going on today's action.
While seeds have fallen around them, Martin Schindler and Ryan Searle have both been quietly impressive - averaging over 95, and dropping one set between them.
Who will triumph here, and face Stephen Bunting's conqueror James Hurrell in the last 16?

Stephen Bunting calls himself the peoples' champion, he has a brilliant walk-on, he gets the crowd pumped up. But he was well beaten.
That's what happens after Christmas at Ally Pally, the shocks come thick and fast. We might just have a couple more today.

Luke Littler was just relentless, there was no nerves, there was no stumble. He was just awesome.
Afterwards he saunters in [to the media conference] like he has just done nothing, and dropped the killer line, "that's the best I have ever felt on the stage, and it's only going to get better".
He will next play Rob Cross or Damon Heta, both top players of course. But to be honest I don't think there is anyone on his side of the draw that I think is going to stop him.

World number one Luke Littler produced a dominant performance to book a spot in the last 16 at the PDC World Championship, but fourth seed Stephen Bunting became the highest-ranked player to exit this year's tournament.
Littler averaged more than 107 and lost just three legs in a 4-0 win over Austria's Mensur Suljovic, demonstrating why he is the man to beat at Alexandra Palace.
The 18-year-old from Warrington is bidding to retain his PDC world crown - a feat that has not been achieved since Scotland's Gary Anderson won back-to-back titles in 2015 and 2016.
Littler was seeded to meet Bunting in the semi-finals, but the world number four was defeated in a deciding set by world number 63 and fellow Englishman James Hurrell.
