# 4d2d — four-two of diamonds

**Fold from every position when the pot is unopened.** 4d2d ranks 159 of the 169 distinct starting hands
(top 90.0%). Against one random hand it wins
33.83% of showdowns and takes 36.72% of the pot.

## What this hand is

Four-two of diamonds. Before any board card is dealt its odds are identical to
4c2c, 4h2h, 4s2s — suits are interchangeable pre-flop, so all
4 combinations in class 42s share the numbers below.
That stops being true the moment the board has suits, which is what the paid
record covers.

## Equity against random opponents

| Opponents | Win % | Tie % | Pot equity % |
| --------- | ----- | ----- | ------------ |
| 1 | 33.83 | 5.79 | 36.72 |
| 2 | 23.29 | 3.15 | 24.64 |
| 3 | 17.85 | 2.50 | 18.91 |
| 4 | 14.72 | 2.15 | 15.64 |
| 5 | 12.77 | 1.88 | 13.58 |

| 7 | 10.42 | 1.63 | 11.12 |

Monte Carlo, 400,000 trials per row, seed 1 —
same seed, same digits. "Pot equity" counts outright wins plus a share of split
pots, which is the number to compare against pot odds.

## 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. "Combos" is how many were averaged.

| Against | Hero pot equity % | Hero win % | Split % | Combos |
| ------- | ----------------- | ---------- | ------- | ------ |
| AA | 17.40 | 17.15 | 0.49 | 6 |
| KK | 18.82 | 18.57 | 0.49 | 6 |
| QQ | 18.81 | 18.57 | 0.48 | 6 |
| JJ | 18.82 | 18.57 | 0.49 | 6 |
| TT | 18.85 | 18.57 | 0.55 | 6 |
| 77 | 18.63 | 17.95 | 1.36 | 6 |
| 22 | 37.77 | 35.09 | 5.37 | 3 |
| AKs | 35.79 | 35.49 | 0.60 | 4 |
| AKo | 38.25 | 37.97 | 0.56 | 12 |
| AQs | 35.71 | 35.41 | 0.59 | 4 |
| JTs | 34.67 | 34.06 | 1.21 | 4 |
| 76s | 35.92 | 32.49 | 6.86 | 4 |

Averaging matters here. Against a single representative the answer shifts with
the suits — J♣T♣ takes 17.77% against Q♣Q♦ but 18.89% against Q♠Q♦, because the
shared club both blocks a flush and removes cards. Averaged over the class the
figure is the same whichever suits you hold, which is what makes it quotable.

## 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. The verdict above is a conventional opening chart,
not solver output. Equity against a random hand is also not equity against a
range: an opponent who raises has better than random cards, and this page does
not model that.
