Why precise preflop frequencies matter for cash-game GTO
When you play cash games, small percentage edges compound hand after hand. GTO (game theory optimal) preflop ranges are not just lists of hands — they are distributions of hands played at specific frequencies. If you treat your open-raising, 3-betting, and calling ranges as rigid sets instead of weighted mixtures, opponents can exploit predictable patterns. By working with frequencies you can:
- Balance value and bluffs so opponents can’t automatically fold to pressure.
- Ensure the correct ratio of strong hands to speculative hands in each position.
- Translate solver outputs to practical table play, avoiding unrealistic all-or-nothing choices.
In practice you’ll convert solver percentages into concrete instructions: what percent of pocket aces you should 3-bet, which suited connectors you should mix between call and fold, and how often to open-raise from each position. Learning to think in frequencies lets you apply GTO concepts without memorizing long charts.
How to calculate and encode preflop hand frequencies
You’ll build a usable GTO preflop range in a few clear steps. Focus on counting combos, interpreting solver outputs, and simplifying ranges into actionable frequencies you can remember during a session.
1. Count combos for each hand
Every two-card hand has a specific number of combinations: 6 for offsuit hands, 4 for suited hands, and 3 for pocket pairs. When a solver says “open 15% from cut-off,” convert that into combos — for example, 15% of 1326 total two-card combos equals how many combos you should include. Counting combos helps you mix partial weights correctly (e.g., include 30% of JTs combos instead of “include or exclude”).
2. Convert solver percentages to hand weights
Solvers output frequencies for actions (open, call, 3-bet). To apply them:
- Start with the recommended percentage for the entire range (e.g., 20% open from MP).
- Select top hands first (pockets, strong broadways) and assign full-weight (100%) to them until you reach most of the target percentage.
- For marginal hands, assign partial weights to reach the exact target — e.g., weight 50% for A5s if you need to hit the exact combo count.
This approach preserves the solver’s balance while giving you a practical checklist: full-included hands, mixed hands with a specified weight, and excluded hands.
3. Prioritize positions and simplify
Build ranges by position: BTN > CO > MP > EP. Use broader ranges on late positions and more selective ranges early. Simplify by grouping similar hands (suited connectors, offsuit broadways, small pairs) and assigning a single frequency to the group when possible. This reduces memorization without destroying balance.
With these basic mechanics set, you’ll be ready to translate sample frequencies into specific open-raise and response charts — in the next section we’ll walk through concrete position-by-position examples and show how to practice them at the table.
Sample position-by-position open-raise frequencies (practical checklist)
Below is a compact, practical set of target open-raise frequencies you can use as a starting point. These numbers are typical solver recommendations for deep-stack cash games — convert them into combos (percent × 1326) when you build exact weighted ranges.
- Button (BTN) — ~40%: aggressive and wide. Expect roughly 530 combos. Full-includes: all pocket pairs, most suited broadways (AKs–A9s, KQs–KJs), offsuit broadways down to ATo/KQo, many suited connectors and one-gappers. Mix weaker suited hands (e.g., 76s, 65s) at partial weights.
- Cut-off (CO) — ~26%: around 345 combos. Full-includes: most pairs, strong broadways, AK/AQ combos. Mix suited connectors and lower suited aces (A5s–A2s) to hit the target.
- Middle Position (MP) — ~18%: ~238 combos. Narrower: top pairs, top suited broadways, selected suited connectors (T9s–87s) and small pairs; mix lower speculative hands down to partial weights.
- Early Position (EP) — ~12%: ~159 combos. Tight and value-heavy: premium pairs, AK, AQs, KQs; very few speculative suited connectors.
How to turn these into a quick at-the-table checklist:
- Make three groups per position: 100% (always open), 50% (mix), 0% (never). Assign the 100% group first, then use 50% weights on marginal hands until you hit the target combo count.
- Examples (CO 26%): 100% group = AA–22, AKs/AKo, AQs–ATs, KQs, AKo/AQo; 50% group = A5s–A2s, JTs–T9s, KJo; 0% group = weak offsuit connectors, low offsuit aces.
- When a hand is mixed, randomly choose which combos to include across suits to approximate the solver distribution — or follow a simple rule (e.g., include two suits this orbit, switch next orbit).
Practical drills and table habits to internalize frequencies
Frequencies become usable through repetition. Use short, focused drills that force you to think in combos and weights until the patterns are automatic.
- Combo-counting drill (10–15 minutes/day): Pick a position and target percentage. List full-includes until you reach ~80% of the target, then add mixed hands with explicit weights until the combo count matches. Verify with 1326×percentage.
- Hotseat practice (live chip/game simulation): Sit on the button and deal out hands to several imaginary opponents. For each dealt hand decide “open / mix / fold” according to your BTN checklist. Rotate positions to practice tighter ranges in EP/MP.
- Flashcard / cheat-sheet method: Create a one-page reference per position: top-100% group, top-50% group, and a short mnemonic (e.g., “BTN: all pairs + broadways + many suited connectors”). Review before every session.
- Post-session review: Review hands where you deviated from your target frequency. Did you over-fold suited connectors or over-open weak offsuit broadways? Adjust the group lists accordingly.
These exercises make mixing feel natural and reduce reliance on rigid lists. Over time you’ll internalize the frequencies enough to make near-solvers choices quickly and without constant chart-checking.
Bringing frequencies to the felt
Turn the planning and drills into small habits: use a one-page cheat-sheet at the table, force yourself to call out “100% / 50% / 0%” when you act, and apply the simple suit-rotation rule for mixed combos. Start with one position (BTN or CO) and add another only after the first feels automatic. If you want to study solver outputs in more depth, tools such as PioSolver can help you inspect exact frequencies and combo distributions.
Be patient with variance and incremental changes. Track hands where your in-session choices deviated from your target frequencies, adjust the group lists, and keep the drills short but consistent. Over time the cognitive load falls away and mixing becomes an intuitive part of solid cash-game play.
Frequently Asked Questions
How do I convert a solver percentage into exact combos?
Multiply the target percentage by 1326 to get the total two-card combos for a full-deck range (e.g., 20% × 1326 ≈ 265 combos). Build the range by including 100% hands first (counting 3/4/6 combos per hand), then add partially weighted hands until the combo target is reached. Round thoughtfully and use partial weights (e.g., 50%) to match the solver mix when needed.
When a hand is mixed, how do I decide which suits to include at the table?
Use a simple, repeatable rule: rotate suits across orbits (include two suits this orbit, the other two next), or pick suits randomly while keeping track across hands. The goal is to approximate the solver’s distribution — consistent, simple patterns are better than trying to perfectly mimic solver suit selection in real time.
How often should I practice the drills to internalize frequencies?
Short daily sessions (10–15 minutes of combo-counting or flashcards) combined with weekly hotseat practice produce steady improvement. Review and adjust after real sessions; expect meaningful gains in a few weeks and more durable, automatic decision-making after a few months of consistent practice.
