It's at the KCOM.

Friday 27 November at the KCOM Stadium, Hull.

No problem with it being at Hull, could be anywhere really as long as it has a decent pitch. I liked the France idea, that could have been good, given a bit more publicity, but not sure about the Friday?

Friday night is a decent time for TV viewers and probably means that there is less conflict with Football.
France would be a good idea, if Catalan are involved and there could have even be some supporters allowed in .

Anyway, it matters not.
The KCOM is a cracking ground and just means 30,000 empty seats instead of 70,000.

Looks like the semis will be Saints, Wigan, Wire and then either Leeds or Catalan.
Should be a couple of cracking semis and a decent final.

Will the semis take place at the same ground as a double header or at the home ground of the top 2 clubs.?

Having it in the Canary islands could have been an option, France would have meant isolating for any travelling fans and players. At least in Canary Islands that's not the case and they have a 32,000 capacity ground (on Gran Canaria) that's big enough for a full sized 100m pitch plus in goal area.
Would have been a fantastic injection to those in the areas that rely on tourism and are on the bones of their .

We can only hope Boris and the rest of his criminals are toppled by a military uprising to stop his genocide and everything gets put back to normal!
