Not many pike come out at night, but there are occasional captures, especially on full moon and at tail end of season.
Never freeline, it gives too much movement of the bait and can lead to deep hooked fish.
I actually go to 'fixed' leads (sinkers) on my hook trace, around half an ounce, and a 2oz paternostered lead on a weak nylon link, then I can fish a sunken float or surface float.
The other rod tends to be ledgered (paternostered), with a floating or popped up bait.
Pollan (a type of fish) float, or I use balsa or cork to pop the bait up.
