A5s against 43s: the numbers
| Hand | Wins | Ties | Loses | Equity |
|---|---|---|---|---|
| A5s | 64.162 | 0.617 | 35.221 | 64.470 |
| 43s | 35.221 | 0.617 | 64.162 | 35.530 |
Both hands are suited hands: A5s and 43s. The two hands share no rank, which makes this a pure matchup of card strength, straight chances and flush chances.
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: 0.62% of boards end in a split pot, and each side counts that as half a win.
By strength against a random hand, A5s holds place 30 of 169 and 43s holds place 150.
| Hand | Boards won, about | Boards tied, about | Boards lost, about |
|---|---|---|---|
| A5s | 17,578,000 | 169,000 | 9,649,000 |
| 43s | 9,649,000 | 169,000 | 17,578,000 |
The total is exact: 16 specific deals times 1,712,304 boards. The three counts are approximate, worked out from the percentages to five decimals and rounded to the nearest thousand.
| Hand | Equity as odds (to 1) | Wins one deal in | Loses one deal in | Pot odds needed to call (to 1) |
|---|---|---|---|---|
| A5s | 1.815 | 1.559 | 2.839 | 0.551 |
| 43s | 0.551 | 2.839 | 1.559 | 1.815 |
The last column is the break-even price: the pot odds a call needs to offer, as a ratio of pot to call.
Who is ahead on which flops
Rainbow flops topped by a ten or better are the best for A5s (67.67%); low rainbow flops (nine high or lower) are the worst (52.12%). A5s stays ahead on all five textures, but the swing between them is large, so how the flop looks matters a great deal.
