Default lagering?

I have a maibock lager, and I wanted to know how you prevent suckback when you lager? I havent put it in my fridge yet because I wanted to ask first. Is it better to have a blow off tube? Or just a airlock

I don't use an airlock at all. I either use a lid with no hole, or a solid bung plug.

A lid? What kind of lid, I think I might have a no holed bung. But I guess it makes sense if its not fermenting. It won't create to much pressure? Or am I just dumb.

No pressure, it's done fermenting. I mean a bucket lid if you're using a bucket, or a solid bung if you're using a carboy.

I've never noticed suck back while cold fermenting. It shouldn't be a big deal of a little sucks back, just use Starsan in the airlock.

When I move my beer to the fridge to lager (or for cold crashing), I replace the bung/airlock with sanitized foil to prevent suck back. It's the cooling of the liquid that causes the vacuum, so if you just replace the airlock/bung with a solid bung or with some sanitized foil, that would be fine. You can always put the airlock back on after the temperature is stable, if you're worried about not having an airlock during lagering. (Although sanitized foil with a rubber band hold it down to cover the fermenter is absolutely fine).

What would be better, foil or solid bung?

Just curious (being new to lagers), why not just lager it in a keg?
