Important things to know
Common questions about 3-betting
A 3-bet is the third raise in a betting sequence. The blinds are the first "bet," an open raise is the 2nd bet (2-bet), and a re-raise is the 3-bet. For example: blinds posted ($1/$2), player raises to $6 (2-bet), another player re-raises to $18 (3-bet).
When out of position (OOP), you need to size larger (3.5x+) to deny the in-position player good odds to call and realize their equity post-flop. In position (IP), you can size smaller (2.5x) since you'll have the advantage of acting last on every street.
Against loose players who call too much, size up 15-25% to punish their wide calling range. Against tight players, you can size down slightly since your 3-bet represents more strength. Against aggressive 4-bettors, consider using a polarized range with larger sizes for value and smaller sizes as bluffs.
A polarized range 3-bets premium hands (AA, KK, AK) and bluffs (suited connectors, suited aces). A linear range 3-bets a continuous range of strong hands. Use polarized ranges against players who don't call 3-bets enough; use linear ranges against calling stations.
3-bet for value with premium hands (AA-QQ, AK) that play well against calling ranges. 3-bet as a bluff with hands that have blockers to premium hands (A5s, A4s block AA/AK) and good playability if called. Your bluff 3-bets should fold out worse hands and have backup equity when called.
