Find patterns with strategy clustering

Choose a postflop node in Study, confirm the acting player, and select Strategy clustering beside the main Strategy and Details tabs. This view requires complete combo-level strategy and range data. It is not available before the flop.

The groups are weighted by the active player's range. A combo that rarely reaches this decision contributes less to the group average than one that arrives often. If Study reports Patterns unavailable, load a decision with the required data rather than interpreting the empty view as a strategic result.

Each pattern summarizes a similar action mix: it may be pure, mostly one action, or a mix of actions. Read the pattern's strategy bar and range share together.

Distinguish combos from weighted combos. The first counts combinations in the group; the second accounts for how often those combinations reach the decision. Two similarly sized lists can represent very different shares of the active range.

The bar-length control also changes the visual comparison:

• Range length scales strategy bars by their share of the active range.
• Full length gives each bar the full width so you can compare its internal action mix.

Changing the scale does not change the strategy or the group membership.

Switch the category view between hands, draws, and the available equity groupings. This shows how familiar hand categories are distributed across strategy patterns.

Inspect a category/pattern cell, its hand matrix, and exact combo details to understand which suits and ranks contribute. Use the matrix's Strategy or Suit display to compare action mix with suit composition.

For example, two top-pair combos may fall into different patterns because they mix actions differently. The clustering identifies that similarity or difference; it does not by itself prove the strategic reason. Check the exact combos and their values before explaining it through blockers or equity.

Open Clustering settings to adjust Clusters and Merge threshold. The cluster count controls how finely the grouping starts; the merge threshold combines groups with sufficiently similar action mixes. The final number of displayed patterns can be smaller than the chosen cluster count.

Start with the defaults, then make the grouping coarser if it is difficult to read or finer if an important difference is hidden. These are analysis settings: they regroup the existing solution rather than re-solving it.

Choose one large pattern and one exception. Describe the action mix, the kinds of hands in it, and the board/range context. Return to Strategy to inspect the exact combinations, or use Blockers to investigate a card-removal hypothesis.

A cluster is a useful summary of this node, not a hand category that must play the same way on another board.
