Pocket aces
Six suit combinations belong to AA, but fixing one exact pair blocks two aces from the opponent deck.

How the result is built
A Hand Class Represents Multiple Card Combinations
Pair, suited, and offsuit labels expand to physical two-card combinations. A known ace of spades removes every combination containing that exact card.

| Hand class | Before blocker | After A-spades blocker | Removed |

| AA | 6 | 3 | 3 |
| AKs | 4 | 3 | 1 |

The matrix encodes suitedness
Pairs occupy the diagonal. Cells above it are suited and cells below it are offsuit, producing four or twelve combinations respectively.
Random opponent means a defined range
The benchmark samples every legal opposing combination uniformly after removing your cards. It does not represent a typical open, call, or tournament range.
Equity is not a starting-hand command
Position, stack depth, future action, rake, and opponents determine strategic value. The matrix reports showdown probability under one explicit comparison.
Weight starting-hand classes by combinations
Before blockers, six suit pairings produce paired hole cards; matching suits produce four versions of two different ranks, and unmatched suits produce twelve. Equal-sized cells in a 13-by-13 grid therefore do not represent equally frequent deals. Strategy comparisons should account for the suit combinations still available.
Worked examples
Ace-king suited
Four concrete same-suit combinations make AKs, each with different blocked flush cards.
Frequently asked questions
Why are there only 169 labels?
Suit-isomorphic starting hands collapse 1,326 concrete combinations into classes.
What does random hand mean?
Every legal opposing two-card combination receives equal weight.
Are the equity values exact?
The data identifies whether a value is exact or a fixed-seed simulation.
Can I inspect concrete cards?
Yes. Selecting a class reveals a card-image example and links to the calculator.
