Before any board card is dealt, 44 holds 50.77% equity against AJs, which leaves AJs with 49.23%. ## AJs against 44: the numbers **Exact preflop results for AJs against 44, in percent** | Hand | Wins | Ties | Loses | Equity | | --- | --- | --- | --- | --- | | AJs | 48.976 | 0.506 | 50.518 | 49.229 | | 44 | 50.518 | 0.506 | 48.976 | 50.771 | We compare a suited hand with a pocket pair. A pair against two higher cards is the classic race: the pair is usually a small favorite or close to even, and each overcard that pairs is a way to take the lead. That is a slim edge: neither hand is far ahead. A split pot comes up on 0.51% of boards, so the wins and the equity differ by half of that. The hand ranking puts AJs at 11 and 44 at 48 out of 169 starting hands. **Boards behind the percentages: 41,095,296 counted in all** | Hand | Boards won, about | Boards tied, about | Boards lost, about | | --- | --- | --- | --- | | AJs | 20,127,000 | 208,000 | 20,761,000 | | 44 | 20,761,000 | 208,000 | 20,127,000 | Exact total: 24 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. **AJs against 44 read as odds** | Hand | Equity as odds (to 1) | Wins one deal in | Loses one deal in | Pot odds needed to call (to 1) | | --- | --- | --- | --- | --- | | AJs | 0.970 | 2.042 | 1.979 | 1.031 | | 44 | 1.031 | 1.979 | 2.042 | 0.970 | 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 Low rainbow flops (nine high or lower) are the best for 44 (76.83%); rainbow flops topped by a ten or better are the worst (45.28%). On rainbow flops topped by a ten or better and two-tone flops the numbers flip and AJs is the one ahead. **AJs against 44 by flop texture, in percent** | Flop | Share of flops | AJs wins | Ties | 44 wins | AJs equity | | --- | --- | --- | --- | --- | --- | | Rainbow, ten or higher | 24.595 | 54.619 | 0.195 | 45.186 | 54.716 | | Rainbow, nine or lower | 6.314 | 22.709 | 0.926 | 76.365 | 23.172 | | Two-tone | 46.545 | 50.310 | 0.318 | 49.372 | 50.469 | | Monotone | 5.212 | 47.981 | 2.816 | 49.203 | 49.389 | | Paired | 17.334 | 47.257 | 0.600 | 52.143 | 47.557 | 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 Each hand has a baseline against a random hand: 65.39% for AJs, 57.02% for 44. Here the change is -16.16 and -6.25 points. **AJs and 44 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 | | --- | --- | --- | --- | --- | | AJs, all flops | 49.229 | 65.393 | -16.164 | 0.75282 | | AJs, rainbow, ten or higher | 54.716 | 65.393 | -10.677 | 0.83673 | | AJs, rainbow, nine or lower | 23.172 | 65.393 | -42.221 | 0.35435 | | AJs, two-tone | 50.469 | 65.393 | -14.924 | 0.77178 | | AJs, monotone | 49.389 | 65.393 | -16.004 | 0.75526 | | AJs, paired | 47.557 | 65.393 | -17.836 | 0.72725 | | 44, all flops | 50.771 | 57.023 | -6.252 | 0.89036 | | 44, rainbow, ten or higher | 45.284 | 57.023 | -11.739 | 0.79414 | | 44, rainbow, nine or lower | 76.828 | 57.023 | +19.805 | 1.34732 | | 44, two-tone | 49.531 | 57.023 | -7.492 | 0.86861 | | 44, monotone | 50.611 | 57.023 | -6.412 | 0.88755 | | 44, paired | 52.443 | 57.023 | -4.580 | 0.91968 | ## Does a shared suit matter? Suit overlap shows up in the numbers. With a suit in common 44 has 50.95% equity, and with none in common it has 50.59%. 44 does better with a shared suit, by 0.36 points. **AJs against 44 by suit overlap, in percent** | Deals | Specific deals | Share of deals | AJs wins | Ties | 44 wins | AJs equity | | --- | --- | --- | --- | --- | --- | --- | | Share a suit | 12 | 50.00 | 48.779 | 0.543 | 50.678 | 49.050 | | No shared suit | 12 | 50.00 | 49.174 | 0.468 | 50.358 | 49.408 | ## 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 Say each player puts $100 in before the flop, making a $200 pot.
