ok, let's put it this way:

Before any opponent has their cards their range is 100%

If an opponent raises, theoretically his range is smaller than 100%, let's say, 30%

If he re-raises, his range should be even smaller than that, so let's say 10%

So if he only raises once, his range is 30%, but against a re-raise it's a lot tighter, so I wasn't saying "he only raises 30% of hands", but if someone 4bet/shoves you, their range must be very tight, yes?

And if he only 4bets JJ+, AQo+ then i'm a 42/57 underdog yeah.
