Ranges

In poker, you never know exactly what cards your opponent holds. Instead, experienced players think in terms of ranges, the complete set of hands a player might reasonably hold given everything they have done in the hand. Mastering range-based thinking is the single most important conceptual leap from beginner to intermediate play.

Quick Take

• Stop guessing one exact hand; start thinking in distributions.
• Hand notation and combo counting make ranges easier to read and compare.
• Good range thinking improves board reading, balance, and exploitation.
• TrainPoker reinforces this by grading repeated spots against its chart set.

What Is a Hand Range?

A hand range is the collection of all possible hole card combinations a player could have at a given point in the hand. Rather than guessing "my opponent has Ace-King," a GTO-trained player asks "what is the distribution of hands my opponent would play this way?"

When a tight player open-raises from UTG, their range might include hands like QQ+, AK, and AQs. When the BTN faces a limp, their 3bet range might be much wider. Every action a player takes narrows or widens their perceived range.

Hand Notation

Poker hand ranges use a standard shorthand notation. Once you learn it, you can read solver outputs and training materials fluently.

The + suffix on a pair (e.g., QQ+) means that pair and all higher pairs. The + suffix on a non-pair hand (e.g., ATs+) means that hand and all suited versions with a higher kicker, up to AKs.

Counting Combinations

Not all hands appear equally often. Pairs have fewer combos than non-pairs.

• Any suited hand (e.g., AKs): 4 combinations
• Any offsuit hand (e.g., AKo): 12 combinations
• Any pair (e.g., QQ): 6 combinations

This matters when you think about an opponent's range. If someone 4bets and you put them on QQ+/AKs, that is only 6+6+6+4 = 22 combinations. Knowing how many combos are in a range helps you estimate how often they have each hand.

Tight vs Loose Ranges

Ranges are often described along two axes: tightness (how many hands are included) and aggression (whether those hands are played passively or aggressively).

Tight ranges include fewer total hand combinations, typically premium holdings. A Nit (tight-passive player) opening UTG might play only the top 10-12% of hands. Tight ranges are easier to read and exploit.

Loose ranges include a broader spectrum. A LAG (loose-aggressive player) on the BTN might open 40% or more of hands. Loose ranges are harder to play against because they include many different hand types: strong pairs, suited connectors, speculative hands, and bluffs.

Why Ranges Matter for GTO Play

Game Theory Optimal (GTO) strategy is defined entirely in terms of ranges. The solver does not decide "I have AKs, I should 3bet." It asks: "From this position, facing this action, what is the optimal strategy, or distribution of actions, for each hand in my range such that my opponent cannot profitably exploit me?"

When you internalize range thinking, several things improve:

Board texture reading: You evaluate how a given flop interacts with your entire range, not just your specific hand. A K72 rainbow flop helps your UTG opening range much more than your BTN calling range. That difference drives c-bet frequency decisions.

Balancing: A balanced range includes both value hands and bluffs in appropriate proportions. If your 3bet range only includes AA-QQ and AKs, a thinking opponent can always fold when you 3bet because you have no bluffs to threaten them with.

Exploiting opponents: Once you understand what a balanced range looks like, you can spot when your opponent is unbalanced: too many bluffs, too many value hands, or too passive a range. Deviation from balance is exploitable.

Building Ranges in Practice

Start with a simple framework. For each position, ask:

1. What is my value range? Hands I open for value, or the hands that profit from getting called.
2. What are my bluffs? Hands I add to make my range harder to read, such as blockers or suited connectors with good playability.
3. What do I simply fold? Hands with negative expected value even accounting for fold equity.

In TrainPoker, every drill hand presents a situation where you apply this thinking. The GTO chart for your position gives the recommended action for that spot. Over many hands, tracking your accuracy per position, spot type, and individual hand reveals where your range construction deviates from optimal. Those deviations become your weak spots.

Summary

• A range is the set of all hands a player could hold given their actions.
• Standard notation (AKs, QQ+, 87s) lets you describe ranges precisely.
• Tight ranges are narrower; loose ranges are wider.
• GTO strategy is entirely range-based. You cannot play optimally by thinking only about your own cards.
• Understanding ranges unlocks board texture analysis, balance, and opponent exploitation.
