TT against 66: the numbers
| Hand | Wins | Ties | Loses | Equity |
|---|---|---|---|---|
| TT | 80.697 | 0.462 | 18.841 | 80.928 |
| 66 | 18.841 | 0.462 | 80.697 | 19.072 |
The matchup is pocket pairs on both sides, TT against 66. A pair against a smaller pair is the classic crush: the smaller pair needs one of its two remaining cards to make a set.
A gap this wide means 66 is in trouble before the flop and has few good runouts. About 0.46% of boards chop the pot, which is why equity sits slightly above the win figure for both hands.
In the ranking of all 169 starting hands, TT is number 5 and 66 is number 17.
| Hand | Boards won, about | Boards tied, about | Boards lost, about |
|---|---|---|---|
| TT | 49,744,000 | 285,000 | 11,614,000 |
| 66 | 11,614,000 | 285,000 | 49,744,000 |
Exact total: 36 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.
| Hand | Equity as odds (to 1) | Wins one deal in | Loses one deal in | Pot odds needed to call (to 1) |
|---|---|---|---|---|
| TT | 4.243 | 1.239 | 5.308 | 0.236 |
| 66 | 0.236 | 5.308 | 1.239 | 4.243 |
The last column is the smallest pot odds, written as a pot-to-call ratio, at which a call breaks even with this equity.
Who is ahead on which flops
Split by what the flop looks like, TT peaks at 86.28% on paired flops and bottoms out at 66.40% on low rainbow flops (nine high or lower). TT stays ahead on all five textures, but the swing between them is large, so how the flop looks matters a great deal.
| Flop | Share of flops | TT wins | Ties | 66 wins | TT equity |
|---|---|---|---|---|---|
| Rainbow, ten or higher | 24.595 | 83.898 | 0.253 | 15.849 | 84.025 |

| Paired | 17.576 | 85.922 | 0.724 | 13.354 | 86.284 |
