Sklansky's Large Ante (play looser) v. Small Ante (play tighter) rule

[Scorpius]

I'm reading Sklansky's "The Theory of Poker" where he discusses the ante structure. He includes "forced bets" in the his use of the term "ante". He says to play looser when the ante is large "in comparison to future bets", but he doesn't really explain what future bets he is talking about. Do any of you understand what he is talking about? If so, I would appreciate some enlightenment. It is confusing to me because in limit poker the small bet and big bet are constant and their ratio to prior bets seems to be about the same. Does anyone know what he is talking about? Thanks.
