What Preflop Aggression covers

Move from "should I enter the pot?" to "how should I respond when someone already has?" — 3-bets, squeezes, 4-bets and the battle for initiative.

Understand 3-bets, 4-bets, squeezes and the battle for initiative.

Learning objectives

  • Build and read 3-bet ranges as a function of the opener’s range, not just hand strength
  • Distinguish linear from polarized construction and know when each applies
  • Handle 4-bets, 5-bets, squeezes and short-stack rejams from both sides of the aggression
