Hey guys,
ok, I already agreed to myself I won't do this, but here we go...
Let's assume we want to have a balanced standard strategy (if not, you do whatever you want, I don't care). You can go two ways: capping and calling with a balanced range, or calling our entire range. Both can and will be fine, once we can execute them perfectly - but that's not as easy as it sounds. So let's examine, why do we cap?
We cap, because the top of our range wants to get value (not to make 6 outers fold, like sim5... mentioned). Against like a BU vs CO 3betting range you want to cap 77+, AT+ for value. As you can see, this range is heavily imbalanced, cause we hit an A a lot, broadways some, anything else very rarely. We'd definitely want to add some hands in there, that will make our range weaker on A hi boards, and stronger on most other boards. Now you could start to figure out, what hands should we add, but it would be too many, we'd cap way too often if we want to keep our range balanced. Therefore we'd probably need a strategy where we cap premiums just a certain percentage of the time randomly (that a human mind cannot execute).
The second problem is that your calling range gets weak, and very very capped on most boards, meaning you cannot turn enough hands to value and bluffraises, and will need to call down with shitty hands (at least shittier than if you don't cap). Also you'll less often hit the most frequent A hi boards, that we have to look out for.
So in short summary: capping preflop a balanced range HAS more value, than calling, however working it out perfectly is nearly impossible, and requires you to have an RNG nearby every time you play. Also, it makes your future streets really hard to play, cause your hands a re weighted in your range, meaning the frequencies =/= combos, making the calculations close to impossible. And it won't be as profitable, cause you loose a lot of the original intention of capping (getting value with the top of our range). Not to mention that people till these days play awful against pure strategies, but that's obviously doesn't relate closely to our point.
Just as an example:
Spoiler
I never 3bet the BB HUHU, cause I find that finding a balanced 3betting/calling range there is as pointless as finding a capping range. I played a friendly HUHU match against dats, who had a quite okayish, but not really balanced 3betting range. This hand is a great example, why you shouldn't be doing that. (My plan was to raise any turn except an 8 or a 3.)
Pre Flop: (pot: 60) Hero has 3♦ 8♦
Hero raises to 80, BB calls 40
Flop: (160, 2 players) K♠ Q♦ A♠
BB checks, Hero bets 40, BB raises to 80, Hero calls 40
Turn: (320, 2 players) 8♥
BB bets 80, Hero calls 80
River: (480, 2 players) A♣
BB checks, Hero checks
BB shows 4♦ T♠ (One Pair, Aces) (Pre 61%, Flop 74%, Turn 16%)
Hero shows 3♦ 8♦ (Two Pair, Aces and Eights) (Pre 39%, Flop 26%, Turn 84%)
Hero wins 480
