i really like the ideas of manipulating villain's ranges based on what you know of their tendencies, and winning the battle of mistakes. especially at the micros where mistakes are rampant.
as for manipulating the potsize, i don't really buy into the PNLH "you want this SPR for these type of hands" etc, in my opinion it's best to think of manipulating your opponents range/the potsize as almost the same. if you 3 barrel TPTK vs a guy who doesnt call 3 barrels with worse than two pair, you've manipulated his range - you've made it stronger than yours (for calling the third barrel) and your river bet will likely be -EV.
however if you decide to check the turn vs this guy on dry boards (wet boards often require hand protection more as one card still to come yields equity for villain's ranges), you have manipulated both the potsize and your opponents range. and can v.bet more rivers as a result, as turn checks are often interpreted as weakness etc etc.
