It is more you need to loosen up when antes kick in. You need to play more hands as an orbit cost you more.
Go with whatever your multiple of the BB was. With ante maybe add 1 BB.
If you have the stack you can afford to play tight and bully at times.
If you are short stacked you just need to play relative to the BB.
In the money or close more aggressive is not necessary the way to go but there are times you are going to need to gamble.
