This is the nineteenth match in our group stage, but there’s been a change to the schedule: from Group 3, it would’ve been Vicky Neale against Sunil Singh. Unfortunately, some grade A eejits have made a situation where Sunil can’t concentrate on the competition any more, so he’s had to pull out.

Vicky had already written her pitch, and there’s no way we’d keep it from you, so we present it below. I’ve also added a bit of fun maths from my own collection to make up the slack. There’s no voting today, and it’ll count as a win for Vicky.
