The hardest seat, the deepest stacks: aces raise, kings call with a wince, and discipline does the rest.
4-bet almost nothing but aces. Even KK often prefers a call — building a 1000bb pot preflop with one pair is a strategy of despair.
You raised the small blind, the big blind 3-bet with position. Every postflop street will be played at a disadvantage — plan accordingly.
Assumes a standard 3-bet; 4-bet to ~2.2–2.5x the 3-bet. Deep, favor calls over 4-bets — a 4-bet pot at 500bb+ commits you with range disadvantage.
