Let's say you open in late position and there's a grinder in the blinds 3-betting the crap out of you. Let's say he goes completely bananas and 3-bets like 40% in this spot because he sees you as "weak" or whatever the reason is. Let's say we're playing a balanced range so we fold some to this, we call some and we 4-bet some according to a range we memorized at home.
So if we're playing a balanced range that means we can't be exploited right? But what if he 3-bets just way too high and we don't adjust our balanced range? We're still not exploited?
