# 75s vs 64s: preflop equity

75s is a big favorite over 64s before the flop: 60.10% to 39.90% equity, counted exactly over every board, with the split by flop type and suit.

Before any board card is dealt, 75s holds 60.10% equity against 64s, which leaves 64s with 39.90%.

## 75s against 64s: the numbers

**Exact preflop results for 75s against 64s, in percent**

| Hand | Wins | Ties | Loses | Equity |
| --- | --- | --- | --- | --- |
| 75s | 56.407 | 7.385 | 36.208 | 60.099 |
| 64s | 36.208 | 7.385 | 56.407 | 39.901 |

75s and 64s are both suited hands. Neither hand shares a rank with the other, so this is a contest of high cards, connection and suits.

That is a modest edge, the kind that shows up over many hands and is easy to miss in one. Ties are part of the picture: 7.39% of boards end in a split pot, and each side counts that as half a win.

The hand ranking puts 75s at 124 and 64s at 138 out of 169 starting hands.

**Boards behind the percentages: 27,396,864 counted in all**

| Hand | Boards won, about | Boards tied, about | Boards lost, about |
| --- | --- | --- | --- |
| 75s | 15,454,000 | 2,023,000 | 9,920,000 |
| 64s | 9,920,000 | 2,023,000 | 15,454,000 |

Exact total: 16 deals times 1,712,304 boards. The other three counts come from the five-decimal percentages and are rounded to the nearest thousand, so read them as approximate.

**75s against 64s read as odds**

| Hand | Equity as odds (to 1) | Wins one deal in | Loses one deal in | Pot odds needed to call (to 1) |
| --- | --- | --- | --- | --- |

| 64s | 0.664 | 2.762 | 1.773 | 1.506 |

The last column is the break-even price: the pot odds a call needs to offer, as a ratio of pot to call.
