Pro Tip with Apestyles: Lock in Your Preflop and Postflop Checklists

Preface

In Texas Hold'em, systematic decision-making is key to consistent profitability. Professional players often use "checklists" to reduce emotional errors. This tutorial draws on Apestyles' approach to help you build your own preflop and post-flop checklists, ensuring every action is data-driven.

Preflop Checklist

1. Hand Selection

• Position First: In early positions (UTG, UTG+1), only play about 10-15% of strong hands, such as TT+, AQs+, AKo. In late positions (BTN, CO), you can loosen up to about 30%, including suited connectors and small pairs.
• Opponent Tendencies: Against tight-passive players (nits), you can raise to steal blinds; against calling stations, raise for value.
• Pot Odds: When facing a raise, calculate the required equity using the formula. For example, calling a 3BB bet with a pot of about 4.5BB requires roughly 30% equity.

2. Action Decisions

• Raise Sizing: With no information on opponents, a standard raise is 2.5-3BB (big blind). When defending against blind steals, you can 3-bet to about 8-10BB.
• Call or Fold: Avoid calling preflop raises with weak hands, especially out of position. Folding is a low-risk decision.

Post-Flop Checklist

1. Flop

• Evaluate Board Texture: Dry boards (e.g., K♠7♦2♣) are better for continuation bets (c-bets) because opponents rarely hit; wet boards (e.g., 9♠8♠6♣) require caution as opponents may have straight or flush draws.
• Position and Range Advantage: In position (BTN) as the preflop raiser, you can c-bet frequently (about 50-70%). Out of position (BB), you typically check-call or check-raise.
• Handling Draws: With an open-ended straight draw or flush draw, consider a semi-bluff raise (treating the draw as a proxy for value). Calculate pot odds to decide whether to continue.

2. Turn

• Board Changes: If the turn completes a draw (e.g., a flush card comes) and you hold the draw, bet for value; if not completed, continue semi-bluffing.
• Opponent Range: After opponents call on the flop, their range typically includes top pair, draws, or slow-played strong hands. If the turn is a blank, bet to force them off weak pairs.
• Bet Sizing: Usually bet 50-75% of the pot. Bet larger on wet boards for value, smaller on dry boards.

3. River

• Value Bet: When your hand ranks in the top 50% of your opponent's calling range, bet for value. For example, with top two pair or better, bet about 2/3 pot.
• Bluff Check: Ensure your bluffs have reasonable blockers (e.g., holding the A♦ blocks a flush draw). Bluff frequency should match pot odds; for a 75% pot bet, bluffs should not exceed about 30%.
• Check-Call: When your hand is of medium strength (e.g., third pair), check-call is appropriate to avoid being raised by strong hands.

Practical Application Example

Assume you are on the BTN with A♠K♠, CO folds, you raise to 3BB, and the big blind (BB) calls.

• Flop: K♦7♠2♣. The board is dry, and you have top pair top kicker. According to the checklist, you should c-bet about 2/3 pot.
• BB calls. Turn: 5♠. A blank, and you now have a flush draw. The checklist suggests: bet about 2/3 pot to both get value and protect your hand.
• BB calls again. River: 3♦. No pair or straight possible. You consider a value bet of about 1/2 pot, as your opponent may hold KQ, KT, or other weaker Kx. If your opponent raises, you can fold (they might have K7 or a set).

Summary

The core of the checklist is de-emotionalization. By following fixed steps, you can make correct decisions faster in complex situations. It is recommended that players record their hand histories and continuously refine their checklists. Remember: preflop position and hand selection determine the win probability for the entire hand, while post-flop bet sizing and board reading generate profits.
