nah;
the reason the toy game works that way is because there is no chance of having to play OOP for three streets after getting called.
It's true that in a PURE PvsBC situation position is more or less a non factor because the bluff catcher has no incentive to bet in or out of position and will always check to the raiser or check back if checked to (Pvs BC = Polar vs bluff catcher) where one player has just nuts and air and the other is capped and bound in such a way that he beats all of the polar range bluffs and loses to all the value hands.
I def understand why it could seem like it would at a glance, but it does not follow that a pr-flop range should be constructed in a polarized way intentionally when OOP.
The reason a player in position can afford to polarize a 3 bet range pre-flop is because it is generally not good to call three bets out of position and take flops in 3 bet flops with a capped range against an uncapped range OOP.
The reasons its better to use a depolarized range pre-flop OOP than a polarized range is because; the way to beat a polarized range is to NOT play 4 bet or fold against it, just call more often. When IP you can call wide and go to the flop with a positional advantage against a range that, if polarized, will contain a bunch of junk.
think about it, if you knew for a fact you would be called you would DEF 3 bet a value only range right? Of course, because your bluffs have no fold equity and because you will need strong hands to content with villain's positional advantage and because your strong hands get value by raising and getting called pre-flop.
If you knew for a fact you would only be 4 bet or folded to then you would play a super polarized range because your opponent would be making mistakes by playing 4 bet or fold against a range that is all nuts and bluffs. If villain knows you're polarized (nuts and bluffs) he would call more often to avoid raising into the nuts AND keep your bluffing range in going to the flop.
Because good players tend to play more 4 bet or fold OOP vs a 3 bet good players polarize their 3 betting ranges in response.
Because good players call a lot in position facing 3 bets from OOP (if deep enough), good players know to play a linear value injected 3 bet range in response to their opponent's not folding a ton and not 4 betting all that much.
So, as for trying to create a polarized situation when OOP because there is no positional advantage when ranges happen to be in a PvsBC distribution is not gonna work.
Yes, when it happens that ranges are PvsBC it negates the effects of position
however
you would be bleeding off too much EV pre-flop by trying to force the situation by 3 betting a polarized range pre-flop
