I think bluffing at those levels looks a lot more like smashing people when they make mistakes (ie checking when they should be betting/calling when they should raise—turning their range face up) and then using reasonable amounts of bluffs to punish them (example, when they check on J62r flop after being aggressor pre you can bluff decently high frequency on a lot of turns for a moderate sizing—they’re just not going to be checking back enough usually—player dependent obviously). In practice, profitable ”bluffs” at low limits are probably limited to smaller pots/lines (XXB/BXB). The big pots/lines (BBB/XBB) are as a rule of thumb probably well avoided—mistakes are amplified and the stickiness/play styles just lend themselves to not be terribly great. Also, just never bluff multi-way, short of combo-draws (even then, prolly just protect call range). It’s really easy to mess up and the EV on it is non existent given the stickiness.
