If TT and A4s get all the chips in before the flop, TT owns 66.96% of the pot in the long run and A4s owns 33.04%. ## TT against A4s: the numbers **Exact preflop results for TT against A4s, in percent** | 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. **Boards behind the percentages: 41,095,296 counted in all** | 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. **TT against A4s read as odds** | 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. ## Who is ahead on which flops Low rainbow flops (nine high or lower) are the best for TT (72.96%); monotone flops are the worst (62.80%). TT stays ahead on all five textures. **TT against A4s by flop texture, in percent** | Flop | Share of flops | TT wins | Ties | A4s wins | TT equity | | --- | --- | --- | --- | --- | --- | | Rainbow, ten or higher | 23.867 | 67.035 | 0.176 | 32.789 | 67.123 | | Rainbow, nine or lower | 7.042 | 72.532 | 0.846 | 26.622 | 72.955 | | Two-tone | 46.545 | 65.115 | 0.306 | 34.579 | 65.268 | | Monotone | 5.212 | 61.603 | 2.403 | 35.994 | 62.804 | | Paired | 17.334 | 69.976 | 0.229 | 29.795 | 70.090 | Read the flop types this way: rainbow has three suits, two-tone has two cards of one suit, monotone has three, and paired repeats a rank. ## Compared with a random hand Compared with a random opponent, this matchup shifts TT from 75.01% by -8.05 points and A4s from 59.03% by -25.99 points. **TT and A4s here compared with each against a random hand, in percent** | Case | Equity here | Against a random hand | Change in points | Times the random-hand equity | | --- | --- | --- | --- | --- | | TT, all flops | 66.960 | 75.012 | -8.052 | 0.89266 | | TT, rainbow, ten or higher | 67.123 | 75.012 | -7.889 | 0.89483 | | TT, rainbow, nine or lower | 72.955 | 75.012 | -2.057 | 0.97258 | | TT, two-tone | 65.268 | 75.012 | -9.744 | 0.87010 | | TT, monotone | 62.804 | 75.012 | -12.208 | 0.83725 | | TT, paired | 70.090 | 75.012 | -4.922 | 0.93438 | | A4s, all flops | 33.040 | 59.034 | -25.994 | 0.55968 | | A4s, rainbow, ten or higher | 32.877 | 59.034 | -26.157 | 0.55692 | | A4s, rainbow, nine or lower | 27.045 | 59.034 | -31.989 | 0.45813 | | A4s, two-tone | 34.732 | 59.034 | -24.302 | 0.58834 | | A4s, monotone | 37.196 | 59.034 | -21.838 | 0.63008 | | A4s, paired | 29.910 | 59.034 | -29.124 | 0.50666 | ## Does a shared suit matter? Split by suits, the deals give TT 67.25% when the hands overlap in a suit and 66.67% when they do not. TT does better with a shared suit, by 0.58 points. **TT against A4s by suit overlap, in percent** | Deals | Specific deals | Share of deals | TT wins | Ties | A4s wins | TT equity | | --- | --- | --- | --- | --- | --- | --- | | Share a suit | 12 | 50.00 | 67.021 | 0.453 | 32.526 | 67.248 | | No shared suit | 12 | 50.00 | 66.489 | 0.364 | 33.147 | 66.671 | ## How often this matchup comes up The class pair covers 24 combinations of specific cards in a fixed seat order, 0.0015% of 1,624,350, and 48 (0.0030%) in either order. ## A worked example To see what the equity is worth, imagine $100 each in a $200 pot.
