The Life Cycle of a Poker Player (and my thoughts on live vs online)

Well, for six months, Viffer had a policy of never bluffing Kenny. That is, if he bet big on the river against Kenny, he was never bluffing. For him, that was optimal... if Kenny knows when you're bluffing, your optimal bluffing percentage is 0. Something like that just makes no sense in the context of online poker.

Please explain this, as it makes no sense to me.
