Head-to-head, exact
Against the opponent's whole hand class, not one chosen pair of cards: every combination of it you do not block, each enumerated over all 1,712,304 boards. No sampling. Averaging over the class is what makes the figure the same whichever suits you hold — against a single representative it shifts by more than a point.

What this page cannot tell you
Pre-flop equity is not a strategy. It ignores stack depth, bet sizing and how your opponents actually play, and equity against a random hand is not equity against the range of hands someone would actually raise with.
