Lesson 36 [Intermediate] Sizing and Frequency Trade-off

To maintain balance, you should decrease your betting frequency when you increase your bet size, and increase your frequency when you decrease your bet size.

Basic Strategy

Use small sizes frequently and large sizes occasionally to make it difficult for your opponents to exploit you.

Basic Premises:

• 6-max cash game, 100BB stack
• Bet sizing decisions post-flop
• Balanced range (value + bluff)

Key Principles of Sizing and Frequency Trade-off:

1. Small Size (1/3 pot) = High Frequency (70-80%)

Small sizes give opponents good odds, so they should be used frequently. While they may not induce many folds, the risk is low.

• Situations: When you have a range advantage, on dry boards, including both value and bluffs
• Range Composition: Strong hands + middle hands + draws + air bluffs
• Purpose: Pot control, value extraction, frequent bluffs

2. Medium Size (1/2 pot ~ 2/3 pot) = Medium Frequency (50-60%)

Medium sizes balance value and protection. This is the most versatile size.

• Situations: Standard boards, hands that need both value extraction and protection
• Range Composition: Strong value + strong draws
• Purpose: Balanced approach, pot building

3. Large Size (Full Pot or More) = Low Frequency (20-30%)

Large sizes polarize your range. Use them only with very strong hands or air bluffs.

• Situations: When you have a nut advantage, on the river, with a polarized range
• Range Composition: Nut hands + air (excluding middle hands)
• Purpose: Maximum value extraction, maximum pressure

Why Play This Way:

1. MDF (Minimum Defense Frequency): Opponents must defend at a minimum frequency based on pot odds. Small bets are called frequently, so they should be used often.
2. Risk Management: Large bets incur significant losses when called, so use them only with strong hands.
3. Balance: Mix value and bluffs appropriately at each size to make it difficult for opponents to exploit you.

Situational Responses

1. When You Have a Clear Range Advantage

Use a small size (1/3 pot) with a high frequency (70-80%). Since your opponent's range is weak, you can bet frequently to induce folds or accumulate small value. This is particularly effective on dry boards.

2. When You Have a Nut Advantage

Use a large size (full pot ~ 1.5x pot) with a low frequency (20-30%). Since you monopolize the nuts, you can extract significant value when your opponent has a strong hand. This is effective as a polarized bet on the river.

3. On Wet Boards

Use a medium size (1/2 pot ~ 2/3 pot) with a medium frequency (50-60%). Protection is needed due to many draws, but too large a size carries a high bluff risk. A balanced approach is crucial.

4. When Your Opponent Folds Excessively

Maximize the frequency of small sizes (80-90%). Since your opponent folds excessively, even small sizes are effective, and losses are minimal if called. You can exploit them by increasing your bluffing frequency.

Thought Process

Try to think in this order when deciding your bet size:

1. Range Advantage? Am I structurally favored? Is my opponent favored?
2. Nut Advantage? Do I monopolize the strongest hands?
3. What type of hand do I have? Strong value? Draw? Bluff?
4. Size Selection: Small (1/3 pot) / Medium (1/2~2/3 pot) / Large (Full pot or more)?
5. Frequency Adjustment: How often do I use this size? What about balance?

Example Hand Analysis

Example 1: Small Size, High Frequency on a Dry Board

Game: Cash game 1/2, 200BB stack
Position: BTN (button, in position)
Pre-flop: CO folds, BTN raises $6, SB folds, BB calls $5
Hero Hand: A♠Q♥
Flop: K♣7♦2♠ (Pot $13)
Action: BB checks → BTN ?

Thought Process:

1. “Who is structurally favored on this board?”
   → K-high rainbow dry board. BTN has a range advantage (many overpairs, AK). BB often misses.
2. “What role does my hand play within my range?”
   → A♠Q♥ is an overcard air hand. However, it's part of the BTN's range for continuation betting.
3. “Does my opponent have enough hands to fold / do they call frequently?”
   → On a dry board, BB misses approximately 60-70% of the time. A small size bet with high frequency is effective.

Conclusion: Bet $4 (approx. 1/3 pot)

Comment: On a dry board with a range advantage, use a small size (1/3 pot) with a high frequency (70-80%). This size includes value hands (AK, overpairs), middle hands (77, KQ), draws, and air bluffs (AQ). It gives opponents good odds but induces frequent folds, making it highly profitable.

Example 2: Large Size, Low Frequency on the River (Polarized)

Game: Cash game 1/2, 200BB stack
Position: CO (cutoff, in position)
Pre-flop: CO raises $6, BTN folds, SB folds, BB calls $5
Hero Hand: 8♠8♥
Flop: Q♥8♦3♠ (Pot $13), BB checks, CO bets $8, BB calls
Turn: 5♣ (Pot $29), BB checks, CO bets $20, BB calls
River: 2♦ (Pot $69), BB checks, CO ?

Thought Process:

1. “Who is structurally favored on this board?”
   → CO has a nut advantage (sets, two pair). BB has a one-pair range (Q, pairs 88 or lower).
2. “What role does my hand play within my range?”
   → 8♠8♥ is a middle set, a very strong nut hand. BB is likely to call with Qx.
3. “Does my opponent have enough hands to fold / do they call frequently?”
   → BB called on the flop and turn, so they likely have Qx or a small pair. Extract maximum value with a large size.

Conclusion: Bet $70 (approx. full pot)

Comment: On the river, nut hands extract value with a large size (full pot or more). This size is a polarized range, including only nut hands (sets, two pair) and air bluffs. Although the frequency is low (20-30%), you can get maximum value when called. Since BB is likely to call with Qx, a large size is highly profitable.

Example 3: Medium Size, Medium Frequency on a Wet Board

Game: Cash game 1/2, 200BB stack
Position: BTN (button, in position)
Pre-flop: CO folds, BTN raises $6, SB folds, BB calls $5
Hero Hand: A♥K♥
Flop: K♠9♥7♥ (Pot $13)
Action: BB checks → BTN ?

Thought Process:

1. “Who is structurally favored on this board?”
   → Wet board (flush draws, straight draws possible). Both players can hold a variety of hands.
2. “What role does my hand play within my range?”
   → A♥K♥ is top pair + nut flush draw. A very strong hand needing both value and protection.
3. “Does my opponent have enough hands to fold / do they call frequently?”
   → Protection against draws is needed on a wet board. Balance value extraction and protection with a medium size.

Conclusion: Bet $8 (approx. 2/3 pot)

Comment: On wet boards, strong made hands use a medium size (1/2 pot ~ 2/3 pot). A small size gives draws good odds, while a large size carries a high bluff risk. A medium size balances value extraction and protection, with a frequency of approximately 50-60% for a balanced approach.

Example 4: Adjusting Balance by Changing Size

Game: Cash game 1/2, 200BB stack
Position: CO (cutoff, in position)
Pre-flop: CO raises $6, BTN folds, SB folds, BB calls $5
Hero Hand: 6♦5♦
Flop: A♠K♣3♦ (Pot $13)
Action: BB checks → CO ?

Thought Process:

1. “Who is structurally favored on this board?”
   → A-K high dry board. CO has a range advantage (many AK, overpairs).
2. “What role does my hand play within my range?”
   → 6♦5♦ is complete air. However, it's part of the bluffing portion of CO's continuation bet range.
3. “Does my opponent have enough hands to fold / do they call frequently?”
   → BB is likely to fold if they don't have an A or K. Bluff with a small size and high frequency.

Conclusion: Bet $4 (approx. 1/3 pot)

Comment: On dry boards with a range advantage, use a small size with high frequency. At this time, you must mix not only value hands (AK, AA, KK) but also bluffs (air like 65s) at the same size. If you only bet value with a small size, your opponent can easily exploit you, so you must include enough bluffs to maintain balance.

Answers and Explanations

Question Answer Explanation Question 1 C) Small size (1/3 pot), high frequency (75%) On a dry board with a range advantage, use a small size (1/3 pot) with a high frequency (70-80%). Since your opponent often misses, a small size can induce many folds, and losses are minimal if called. Include value hands, middle hands, draws, and air bluffs to maintain balance. Question 2 C) Full pot or more On the river, nut hands extract maximum value with a large size (full pot or more). If your opponent is presumed to have one pair, they are likely to call, making a large size highly profitable. This size is used with a polarized range (nuts + air), and although the frequency is low (20-30%), it yields maximum profit when called. Question 3 C) Nut hands + air bluffs (polarized) Large size bets are composed of a polarized range. Include only very strong nut hands (value) and complete air bluffs, excluding middle hands. This makes it difficult for your opponent to call with middle hands, allowing you to extract maximum value with strong hands or win large pots with bluffs. Question 4 B) 1/2 pot ~ 2/3 pot On wet boards, strong made hands use a medium size (1/2 pot ~ 2/3 pot). A small size gives draws good odds, leading to insufficient protection, while a large size carries a high bluff risk. A medium size balances value extraction and protection, with a frequency of approximately 50-60% for a balanced approach. Question 5 C) Mix value hands and bluffs appropriately To maintain balance at all bet sizes, you must mix value and bluffs appropriately. If you only bet value hands with a small size, your opponent can easily exploit you (by folding to small bets). Therefore, you must mix not only value like AK but also air bluffs like 65s at the same size to prevent your opponent from distinguishing between them.
