I know we put villains on ranges and a 2 pair is not outside the realm of possibility,
It's just not their whole range. That means that when they call us with 2-pair, that's not indicative of everything they could have done in that spot.

If they call us with 2-pair, but that 2-pair only represents a small fraction of their range, then we get so much value from fold equity that we don't even care about the tiny %-age of the times they call and we lose to 2-pair.
