Raise

Raising is the engine of poker aggression. When you raise, you accomplish several things simultaneously: you increase the pot size, you force opponents to invest more chips to continue, and you represent strength. The decision of when and how much to raise is at the heart of poker strategy. Preflop, raises come in several forms. The open-raise is the most common, establishing your presence in the pot. The 3-bet (re-raise over an open) applies pressure and narrows the field. The 4-bet and 5-bet are escalating levels of aggression that define the strongest confrontations. Each level requires a stronger range because the pot-to-stack ratio increases dramatically. Raise sizing is a critical skill. In MTTs, smaller sizes are preferred because they risk fewer chips while accomplishing the same strategic goals. A 2.2x open-raise achieves nearly the same fold frequency as a 3x raise but costs 27% less when opponents fold. For 3-bets, sizing depends on position: in-position 3-bets are typically 2.5x to 3x the open, while out-of-position 3-bets are 3x to 3.5x because you need to compensate for the positional disadvantage. Postflop, raises serve two primary purposes. Value raises aim to build the pot with strong hands, extracting maximum chips from opponents who will call with worse hands. Bluff raises (including check-raises) attempt to win the pot immediately by representing strength. A balanced player mixes both at appropriate frequencies. The key principle of raising is that it gives you two ways to win: opponents can fold (giving you the pot immediately) or call with worse hands (letting you win at showdown). Calling, by contrast, only wins at showdown. This fundamental asymmetry is why aggressive play is favored in poker.
