Don't get tied into any one strategy right now, we can't know anything properly until after Wednesday when the FA Cup matches are finished.
Be prepared to change your mind as needed.
And remember...
A lot of the time different strategies are posed as if it will be impossible to play it any other way.
The framing often comes down to "how will you manage x Gameweek(s)" and my usual response is in the same way you'll manage the weeks you're not playing Chips - making transfers
The only aim for Chips is like anything else in FPL - to maximise YOUR points.
If that means changing strategy based on fixture announcements then so be it.
The last 3 seasons have been difficult to navigate because of real world events, it's helped to be flexible.
The official World Cup Fantasy game is an absolute mess.
Randomly, someone I was chatting to about something completely different to Fantasy Football said they also do a bit of work for FIFA so I've emailed them to see if they can put me in touch with anyone to clarify.
It's a long shot but I will share if anything comes of it.
