Preflop

What Is Preflop?

Preflop is where every poker hand begins. After the blinds and any antes are posted, the dealer distributes two hole cards (face-down) to each player in Hold’em, or four in Omaha. Players then evaluate their starting hands and decide whether to fold, call, or raise — all before a single community card hits the board.

Despite being the street with the least information available, preflop decisions are the foundation of winning poker. Every mistake made preflop cascades through the rest of the hand. Playing too many weak hands leads to difficult post-flop situations with marginal holdings. Playing too few hands surrenders your fair share of pots. The goal is to construct a preflop strategy that balances hand strength, position, table dynamics, and opponent tendencies.

Preflop strategy has been studied extensively through game-theory-optimal (GTO) solvers and decades of empirical data. The result is well-established opening ranges for each position at the table. While memorizing exact ranges takes time, understanding the principles behind them — tighter from early position, wider from late position, aggressive over passive — will immediately improve your results.

How It Works

The preflop betting round follows a specific sequence:

1. The small blind and big blind post their forced bets.
2. The dealer distributes two hole cards to each player (starting left of the button, clockwise).
3. Action begins with the player to the left of the big blind (Under the Gun, or UTG).
4. Each player, in turn, may fold, call the big blind, or raise.
5. Action continues clockwise. If someone raises, subsequent players must fold, call the raise, or re-raise.
6. The big blind acts last. If no one has raised, the big blind may check (taking a free flop) or raise.
7. Once all action is complete, the hand moves to the flop.

Key preflop actions:

• Open raise: The first voluntary raise, typically 2.5 to 3 times the big blind in cash games, or 2 to 2.5 times in tournaments.
• 3-bet: A re-raise over an initial raise, used with premium hands for value and with select bluffing hands.
• Cold call: Calling a raise when you have no money already in the pot. This action should be used selectively and is generally more viable in position.
• Squeeze: A large 3-bet made after a raise and one or more callers, leveraging fold equity against multiple opponents.

Example

You are playing $1/$2 No-Limit Hold’em at a nine-handed table. You sit in the cutoff (one seat right of the button) and are dealt Ace-Jack offsuit. UTG folds, UTG+1 limps for $2, the next three players fold, and the action reaches you.

You evaluate the situation: Ace-Jack offsuit is a solid hand in the cutoff, especially with only limped action ahead of you. Calling the limp would be passive and miss an opportunity to take control. Instead, you raise to $12 (isolating the limper with a raise that prices out speculative hands).

The button folds, the small blind folds, the big blind folds, and the limper calls. You go to the flop heads-up with position and the initiative — an ideal preflop outcome. The pot is $27.

Your preflop raise accomplished several things: it narrowed the field from potentially six opponents to one, it gave you the betting lead (you can continuation bet the flop credibly), and it ensured you will act last on every subsequent street.

Common Mistakes

• Limping into pots. Open-limping (just calling the big blind instead of raising) is one of the most common and costly errors in poker. It signals weakness, invites multiple callers (making your hand harder to play), and forfeits the initiative. Raise or fold as your default preflop actions.
• Playing too many hands from early position. UTG and UTG+1 require tight, disciplined opening ranges. With six or seven players still to act behind you, the likelihood that someone holds a premium hand is high. Stick to strong hands from early position and save your wider ranges for the cutoff and button.
• Ignoring stack depth. Your preflop strategy should adjust based on effective stack sizes. With 100+ big blinds, suited connectors and small pairs gain value for their implied odds. With 20 big blinds, the strategy shifts toward a push-or-fold approach where speculative hands lose their appeal. Stack-depth charts are available in our poker tools section.

FAQ

What are the best starting hands in Texas Hold’em?

The top starting hands, in approximate order, are: pocket Aces (AA), pocket Kings (KK), pocket Queens (QQ), Ace-King suited (AKs), pocket Jacks (JJ), and Ace-Queen suited (AQs). These hands are profitable from every position and should virtually always be raised preflop. However, poker is situational — even premium hands require adjusting raise sizes and strategies based on table dynamics.

Should you ever just call preflop instead of raising?

Cold-calling (calling a raise) has a place in poker, particularly from the big blind where you already have money invested, or from the button where your positional advantage compensates for the passive action. However, as the first player entering the pot, you should almost always raise rather than limp. Raising builds the pot, takes initiative, and can win the blinds outright. Our strategy guides provide detailed preflop range charts.

How do preflop ranges change in tournaments versus cash games?

Early in tournaments with deep stacks, preflop play resembles cash game strategy. As blinds increase and stacks get shorter, ranges shift dramatically. With 15-25 big blinds, players adopt a “reshove” strategy with wider ranges. Below 10-12 big blinds, preflop becomes a push-or-fold decision with no post-flop play. Cash games maintain consistent stack depths, allowing for more nuanced preflop decisions throughout the session.
