If you've already used your WC/FH then you're probably struggling to decide on a chip strategy to deal with GWs 18+19

If you have all you chips then the obvious* strategy is:
WC - GW16
FH - GW18
BB - GW19

*(this might not be an obvious strategy if GW1/11 Blanks move to GW18/19)

You'll be able to make a more informed decision on chip strategy if you're aware of what kind of Blank and Double GW schedule is likely the second half of the season.

This isn't going to be a normal end to the season; we're not guaranteed big Double Gameweek in GW37.

After GW19, postponements will be caused by:
EFL Cup Final in GW26
FA Cup QFs in GW29
FA Cup SFs in GW32
FA Cup Final in GW37

Most* postponements will move to the free midweeks in:
GW26
GW32
GW37

*one or two postponements will probably have to move to a UCL midweek

So Gameweek 29 is the only guaranteed Blank GW after GW18.

GW29 clashes with the FA Cup QFs.

The FA Cup QFs have caused either 5 or 6 Blank fixtures in each of the last 5 seasons.

Here are the GW29 fixtures:

The postponements caused by the EFL Cup Final, FA Cup SFs and FA Cup Final probably won't become Blank fixtures as they can move to the free midweeks immediately after each of those cup rounds.

But that doesn't leave an obvious Gameweek to move the GW29 Blanks to.

The GW29 Blanks will be decided in the midweek before the GW24 deadline.

The sensible place to move the GW29 Blanks to would be the midweek after GW26, but that would only be possible if neither side is involved in a GW26 postponement that has already been moved to that midweek.

E.g.
Man Utd reach the EFL Cup Final so CHE vs MUN is rescheduled from the weekend of GW26 to the midweek in GW26.

Then Man Utd and Chelsea reach the FA Cup QFs so CRY vs MUN and LIV vs CHE become Blank fixtures in GW29, but neither Blank can move to the midweek in GW26.

GW26 is likely to be the only sizeable Double GW in the 2nd half of the season.

The number of extra fixtures in DGW26 will mostly be determined by how many Blanks are caused by the FA Cup QFs in GW29 and how many of those Blanks will be able to move to the free midweek in GW26.

A Blank from GW1 or GW11 might possibly be moved to DGW26, but most if not all of the rescheduled fixtures in GW26 will be announced after the FA Cup 5th Rd in GW24.

So you'll have more time to prepare for BGW29 than DGW26.
