At 1000bb even the game's most routine spot turns solemn: call wide, proceed only with the nuts or a plan.
3-betting is nearly reserved for the top of the deck. Position and nut potential dictate everything else; offsuit broadways are mostly gone.
The most common confrontation in live poker: button steal, big blind close. Defend wide — but depth decides which half of wide.
Assumes a ~4bb open; 3-bet to ~3x the open in position, ~4x from the blinds — larger as stacks deepen.
