Is there any reason why my old floorboards are nailed, other than that it's
quicker?

As I will want to take my floorboards up in a year or so
I think I should screw the ones I'm repairing and replacing,
but what kind of screw?

As I plan on pulling them up again in a year
maybe a shorter narrower screw
so next year's can be secure?

There are hundreds of different screws on offer...

thanks

If you use a C2 or similar machine to drive the screws in without pre
drilling then you will never lift the boards without splitting and
damaging. So as suggested use a combination bit and pre drill so then
can come out later. On the subject of cut nails and T and G, I have
lifted boards in well over 1000 properties - mainly in London - and
have come across cut nails in oldT and T about 3 or 4 times.
they were normal cut nails - maybe a tad thinner but not significantly
but did get put thru the board thickness not the tongue. Who knows
they may even have been predrilled but I doubt it.
It was normally only on high class houses. Most were ex 6" by 1" pine
with nails directly thru about 3/4 " from the edge
