Depth plus position equals more calls: every suited connector and gapper wants a flop against the small blind's wide, out-of-position range.
Calling ranges widen before 3-betting ranges do — set-mining and suited-connector calls gain value faster than thin 3-bets.
Blind versus blind, and you have position for once. The small blind's raise is wide; your defense should make wide expensive.
Assumes a ~4bb open; 3-bet to ~3x the open in position, ~4x from the blinds — larger as stacks deepen.
