TT against A4s: the numbers
| Hand | Wins | Ties | Loses | Equity |
|---|---|---|---|---|
| TT | 66.755 | 0.409 | 32.836 | 66.960 |
| A4s | 32.836 | 0.409 | 66.755 | 33.040 |
TT is a pocket pair and A4s is a suited hand. The pair is ahead of one card and behind the other, so the board decides how that plays out.
A lead of 33.92 points is large but not decisive: A4s still takes about 328 of every 1,000 deals. 0.41% of boards are ties, so the equity of each hand is its win rate plus half of that.
By strength against a random hand, TT holds place 5 of 169 and A4s holds place 35.
| Hand | Boards won, about | Boards tied, about | Boards lost, about |
|---|---|---|---|
| TT | 27,433,000 | 168,000 | 13,494,000 |
| A4s | 13,494,000 | 168,000 | 27,433,000 |
The total is exact: 24 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) |
|---|---|---|---|---|
| TT | 2.027 | 1.498 | 3.045 | 0.493 |
| A4s | 0.493 | 3.045 | 1.498 | 2.027 |
In the last column, a pot-to-call ratio at or above the figure makes a call break even or better at this equity.
