Flop C-Bet Frequency Chart: UTG vs BB Single Raised Pot K72 Rainbow

Position Scenario Explanation

Assume: 6-max cash game, effective stacks 100BB. UTG opens to 3BB, BB calls. Flop is K♠ 7♦ 2♥ (rainbow board, no flush draws). UTG, as the preflop aggressor, has a range advantage and nut advantage (KK, AK, KQ, etc.), so a high-frequency continuation bet strategy should be adopted.

Recommended Range (UTG's Flop Betting Range)

UTG's flop continuation bet frequency is approximately 70%-80%, including the following hand types:

• Value bets: Top pair or better (AK, KQ, KJs, KK, 77, 22); slow-play AA? Usually AA still bets.
• Semi-bluffs: Backdoor straight flush draws (e.g., A♠ T♠, Q♠ J♠); bottom pair + two overcards (e.g., A8, A9, but watch kicker); middle/low pairs with backdoor draws (e.g., 88 with one ♠).
• Pure bluffs: Hands with no showdown value, e.g., A5o, A4o (no backdoor), and unpaired hands without draws (e.g., QTo, but at a lower frequency).

Hands that are less frequently bet (about 20-30% frequency):

• Middle pairs (TT-88, 55-44) — these are easily outdrawn by opponent's Kx or sets, lack draws, so prefer to check for pot control.
• Some trash hands (e.g., T9o, 86o) — no draws and no showdown value, but bet at a low frequency to maintain balance.

Range Construction Logic

1. Range advantage: UTG's preflop range contains more high cards (AK, AQ, KQ) and strong pairs, while BB's range is wider and weaker. The K72 flop strongly connects with UTG's strong range.
2. Nut advantage: UTG has KK, 77, 22 for sets, and AK (top pair top kicker) — actually AK is top pair, but two-pair combos like K7s are rare. BB will not have KK (preflop 3-bet), but may have 77, 22, and K7s (rare), so UTG still has an edge in nut hands.
3. Bet frequency: GTO recommends high-frequency small bets (about 1/3-1/2 pot) on dry boards with a range advantage. Here, approximately 75% betting frequency is used, with a value-to-bluff ratio of about 2:1.

Adjustment Factors

• Opponent tendencies: If BB folds too often to continuation bets, increase frequency; if BB check-raises frequently, reduce betting with marginal hands.
• Stack depth: Deep stacks increase the value of backdoor draws, so increase semi-bluffs; shallow stacks focus more on immediate showdown value.
• Board texture: On wetter flops (e.g., KQ9 two-tone), UTG's betting frequency should decrease to about 60% because it is more susceptible to check-raises.
• History: If previous continuation bets have been called often, reduce frequency; if opponent folds too much, increase.

GTO Reference (Approximate Numbers)

Note: These numbers are based on typical GTO solver outputs; adjust according to opponent in real games.

Practical Application

1. Bet sizing: On a dry K72 rainbow board, a 1/3 pot bet is standard. It allows weak hands to call while reducing the cost of bluffs. For sets or top pair top kicker, mix in 2/3 pot bets to extract more value.
2. Range separation: Maintain a balanced value-to-bluff ratio. For example, for every 3 value combos bet, include 1-2 bluff combos. Plan ahead preflop which hands to use for continuation bets.
3. Against check-raises: When BB check-raises, UTG should re-raise with strong hands (KK, AK, 77, etc.), while medium-strength hands and bluffs generally call or fold to avoid over-committing.
4. Turn planning: If the flop bet is called and the turn is a blank (e.g., 3♦), UTG should continue betting with most top pairs and draws, and check with middle pairs and air to avoid bloating the pot.

Remember: Frequencies are not rigid numbers but tools to adjust based on opponents. In low-stakes games, many players either over-defend or over-fold, and deviating from GTO can often yield higher profits.
