I really don't think pushing small edges for maximum profit is what makes the money at SSNL. Sure, it may increase your overall profit, but it drastically increases your variance. The way to make money is to control pot size based on your opponent and force them to make incorrect plays, according to the fundamental theorem of poker.

Also, bluffing *can* be done at SSNL. It just has to be the right game and players, otherwise you'll get called down (in which case, refer to other posts about value bets).
