Do you just add up the antes and chop them up into blinds and work from there? Is that a poor strategy or a good place to start?
You can get away with opening a lot smaller relative to the pot. It's in your interest to keep blind steals as small as possible so don't go around and over complicate things. The majority of players who play these are generally playing for fun and are not high level thinkers. Keep it simple and just try and win as many as possible for as cheap as possible.
