Betting sizes serve multiple strategic purposes, from controlling pot growth to manipulating opponent decisions. Smaller bets can induce calls from weaker hands, offer favorable risk-reward ratios, and keep ranges wide, while larger bets create fold equity, polarize hand strength, and maximize value from strong holdings. The choice of sizing also impacts perceived strength, balancing bluffs and value bets to prevent exploitation. Dynamic adjustments based on board texture, player tendencies, and game flow ensure optimal decision-making and long-term profitability.
