Interpreting preflop charts in SSHE

[Yossarian147]

Hey, first post. I'm just learning the game and want to be sure I understand the PF charts. Now I know that they're just guidelines, but at the same time they are specific hand recommendations. So based purely on the logic of the charts--

Loose, late position, raiser + 2 callers are in the pot. Do you call with any pocket pair?

Loose, BB, vs a raise. Do you call with 53s?

What are you "supposed" to do vs raise & reraise from the blinds?

Thanks in advance.
