## A6s against 65s: the numbers

**Exact preflop results for A6s against 65s, in percent**

| Hand | Wins | Ties | Loses | Equity |
| --- | --- | --- | --- | --- |
| A6s | 66.461 | 2.456 | 31.083 | 67.689 |
| 65s | 31.083 | 2.456 | 66.461 | 32.311 |

Both hands are suited hands: A6s and 65s. The two hands share a rank, and the one with the better other card dominates: it wins most kicker battles when that shared rank hits.

That is a clear edge, 67.69% to 32.31%, but 65s still wins often enough that one hand proves nothing. Of every 100 boards, about 2.46 are split pots, and the equity figures already include them.

Place 31 of 169 belongs to A6s and place 128 belongs to 65s in the ranking against a random hand.

**Boards behind the percentages: 20,547,648 counted in all**

| Hand | Boards won, about | Boards tied, about | Boards lost, about |
| --- | --- | --- | --- |
| A6s | 13,656,000 | 505,000 | 6,387,000 |
| 65s | 6,387,000 | 505,000 | 13,656,000 |

Exact total: 12 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.

**A6s against 65s read as odds**

| Hand | Equity as odds (to 1) | Wins one deal in | Loses one deal in | Pot odds needed to call (to 1) |
| --- | --- | --- | --- | --- |
| A6s | 2.095 | 1.505 | 3.217 | 0.477 |
| 65s | 0.477 | 3.217 | 1.505 | 2.095 |

In the last column, a pot-to-call ratio at or above the figure makes a call break even or better at this equity.

## How this was computed

The figures are counted, not estimated: 1,712,304 boards for every suit pattern of the 12 specific deals, with both seven-card hands compared each time. Equity gives half a win for a tie. For the flop rows, a board is counted once under each of the ten flops inside it.
