The "Nash" push-fold ranges are only a "solution" to a game where the only options are push or fold. As soon as you start limping some hands, that alters the EV of the rest of the strategy. e.g. Part of the reason why it's profitable to jam T5s is that villain believes you also jam QQ+. In effect, he has to "respect" your jams, because you play the strongest stuff the same way as the weak hands. T5s benefits greatly from the fold equity generated by the threat of you having a monster. If you arbitrarily take QQ+ out of your jamming range (and villain knows this), he can call your shoves a little bit more often, because he's not going to run into a monster. This will mean that the bottom of the original shoving range will no longer be profitable. Indeed, your shoving range will be a fair bit weaker if you've taken out all the big hands.
In the real world, this is often the case in low stake MTTs. If someone jams 15bb and you have JJ, it's a snap-call, because you can be pretty sure that villain doesn't have QQ+, because he would have minraised to injuce. Many players look at a push chart and jam everything on it apart from monsters, but this means they are jamming a weak range and minraising a strong one, meaning both ranges are unbalanced. A stronger strategy would be to have a raise-fold strategy with some weak hands that are used to balance the raise-calls with monsters. The remainder of the hands can be shoved, as they will still have the roughly the same average strength as the original push-fold strat.
The same applies to limping. If you want to limp aces to induce, you also need to limp
-fold some weak hands. Villain isn't going shove over your limp if you
always have aces, but if you're balanced, your "threat" of aces means some weak hands get to see a cheap flop. i.e. You limp some weak hands that do better by potentially seeing a cheap flop than they do by jamming.
To use an abstract example, imagine a one-card game, where your playable range is A to 2, with A being value and 2 being a bluff. You could just shove all hands, but it might be more profitable instead to limp-call A, K, Q and balance by limp-folding with 3 and 2, leaving J-4 as shoves. A real NLH strategy is much more complicated than this, because different hands have different amounts of post-flop playability, but hopefully you get the gist of the idea of balancing the ranges for each action.
