Bottom of Range

What is Bottom of Range?

Bottom of Range refers to the weakest hands in a player's range for a given situation. In poker, a range is the set of all possible hands a player could have, and it is typically divided into three parts: top, middle, and bottom. The bottom of range consists of the hands that have the lowest equity against an opponent's likely holdings or that are least likely to win at showdown.

Strategic Importance

Understanding and managing the bottom of your range is crucial for balanced play. Strong players use their bottom-of-range hands for specific purposes:

• Bluffing: Since these hands have little showdown value, they are prime candidates for bluffs. For example, if you raise preflop and the flop comes with draws, your weakest hands (like a gutshot or backdoor flush draw) can be used to continue betting as a semi-bluff.
• Checking or Folding: In many spots, the bottom of range is simply checked or folded to avoid losing chips with weak holdings. This is especially true when facing aggression from an opponent who likely has a stronger range.
• Balancing: To avoid being too predictable, players may occasionally slow-play or take unusual lines with bottom-of-range hands. For instance, checking back a weak top pair on a dry board to induce bluffs on later streets.

Example

Consider a preflop raise from the button and a call from the big blind. The flop comes K♠ 8♥ 2♦. The button's range might include hands like KQ (top), 88 (middle), and 76s (bottom for a flush draw). If the button bets, the 76s is a typical bottom-of-range hand used as a bluff continuation bet.

Distinction from Other Parts

• Top of Range: Strongest hands (e.g., sets, top pair top kicker) that are usually value-bet.
• Middle of Range: Medium-strength hands (e.g., middle pair, weak draws) that often require careful play (check-call or fold).
• Bottom of Range: Weakest hands that have low equity and are often discarded or turned into bluffs.

Common Mistakes

• Overbluffing: Using too many bottom-of-range hands as bluffs can make your range unbalanced and exploitable.
• Calling too much: Weak hands should rarely be called with pure showdown value unless pot odds and implied odds justify a call (e.g., with strong draws).

In Game Theory Optimal (GTO) Play

GTO strategies assign mixed frequencies to bottom-of-range hands. For example, a solver might suggest checking 30% of the time and betting 70% with a specific weak hand to balance value bets. The exact frequencies depend on board texture, stack sizes, and ranges.

For amateur players, a simpler rule is: if a hand has little chance to improve and no showdown value, consider folding or bluffing with it—but not both too often.
