TT vs 77 Odds: Pocket Tens vs Pocket Sevens
Last updated: May 27, 2026
Pocket Tens (TT) wins 81.8% of the time against Pocket Sevens (77) preflop. 77 wins 16.5% with ties at just 1.7% — the lowest tie rate among TT's medium-pair domination matchups. The three-rank gap between TT and 77 reduces 77's straight draw connectivity to boards involving tens, meaning TT smashes broadway boards, nine-high boards, and eight-high boards unambiguously. 77's primary danger to TT is concentrated on seven-high boards and connected low boards like 5-6-7 and 6-7-8 where OESD equity supplements set equity.
The Exact Number: 81.8% vs 16.5%
TT's 65.3-point advantage over 77 continues the progressive pattern: TT vs 99 (81.5%), TT vs 88 (81.7%), TT vs 77 (81.8%). Each step down in the lower pair's rank adds approximately 0.1–0.2 pp to TT's equity because the lower pair's secondary equity sources (straight draws, connected board scenarios) shrink as the rank distance from ten increases. The 1.7% tie rate reflects the reduced frequency of boards where both sevens and tens complete identical straights.

77's 16.5% equity is primarily set-flopping equity (~10.4%) plus OESD and straight draw equity on connected low boards (~2.6%), runner-runner scenarios (~0.8%), and miscellaneous tie/board-play situations (~2.7%).
Does the Suit Matter?
Suit combinations affect TT vs 77 by approximately 0.4 percentage points — consistent with other pair-vs-pair matchups. 77's primary equity driver (set outs) is suit-independent; the small variation comes only from flush draw possibilities when 77 shares a suit with a ten. The 1.7% tie rate is stable across all suit configurations because tie equity comes from shared straight completions, not suit distributions.

Post-Flop: Seven-High Boards and 5-6-7 OESD Scenarios
Post-flop in TT vs 77, the board texture determines nearly everything. A seven on the flop is catastrophic for TT; a ten on the flop is game-over for 77; and low connected boards (5-6-7, 6-7-8) give 77 its secondary equity source. The 5-6-7 flop with a flopped set of sevens is TT vs 77's most equity-shifting scenario — far more dangerous than the equivalent board against 88 or 99.

Why 77 Rarely Threatens TT on Broadway Boards
Against 99, TT must navigate boards featuring nines, eights, and sevens with awareness that 99 has proximity to straight completions. Against 77, TT benefits from an important simplification: broadway boards (J-Q-K-A combinations) are purely TT's domain. A J-Q-K flop doesn't help 77 with straight draws in the same way it might help 99 (where 7-8-9 or 8-9-T boards create dual set+straight threats). 77's straight draws require 4s, 5s, 6s, 8s, 9s — none of which appear on broadway boards.
This means that approximately 60% of all flops — those containing at least one high card (9 or above) with no seven — are near-pure TT territory. 77's meaningful secondary equity is concentrated in a narrow band of low connected boards: 4-5-6, 5-6-7, 6-7-8, 5-6-8. Outside these boards, 77's sole winning path is the set of sevens.
77 equity sources vs TT
- Flop a set of sevens (11.8%) × win from there (88.5%)~10.4%
- Connected low board draws (5-6-7, 6-7-8, 4-5-6)~2.6%
- Runner-runner quads or boats~0.8%
- Board-play ties and miscellaneous runouts~2.7%
- Total 77 equity16.5%

Frequently Asked Questions
What are the exact TT vs 77 preflop odds?
Pocket Tens (TT) win 81.8% of the time against Pocket Sevens (77) preflop. 77 wins 16.5% and ties account for 1.7%. This is a domination matchup — TT holds two cards ranking above 77's pair, leaving 77 with only two outs (the remaining sevens) as its primary winning path. 77 flops a set approximately 11.8% of the time; when it does, 77 becomes roughly an 88.5% favourite to win the hand. The 1.7% tie rate is the lowest among TT's medium-pair domination matchups because sevens and tens share fewer straight combinations, making board-play tie scenarios less frequent.
Why does TT vs 77 have the lowest tie rate in medium-pair dominations?
The tie rate in pair-vs-pair matchups is driven by shared straight completions — boards where both hands end up with identical five-card straights. Tens and nines (TT vs 99) are adjacent, meaning boards like 7-8-9-T-J are common and create identical straight outcomes for both hands. Tens and sevens (TT vs 77) are separated by three ranks, so shared straights require more specific board configurations — a 6-7-8-9-T board ties TT and 77, but this combination is less common than the 7-8-9-T-J tie board. The result is that TT vs 77's 1.7% tie rate is 0.1 pp lower than TT vs 99's 1.8%.
Which boards are most dangerous for TT against 77?
TT's most dangerous post-flop scenarios against 77 are: (1) Seven-high boards (7-x-x) where 77 has flopped a set — TT is an 11.5% underdog. (2) 5-6-7 flop — this is 77's nightmare and TT's biggest worry simultaneously: 77 flops a set on the most connected low board possible, gaining set equity plus OESD equity (4 or 8 completes a straight) plus the board itself contains a made straight for 4-5-6-7-8. On 5-6-7, TT's equity drops from 81.8% to approximately 68.3%. (3) 6-7-8 boards give 77 a set on a connected board where 5-9 also completes straights. Broadway boards (J-Q-K, Q-K-A, K-A-J) are pure TT territory against 77 — 77 has almost no secondary equity on high boards.
How does 77 play differently against TT vs 99?
77's strategy is virtually identical to 99's against TT — both are pure set-mining hands. However, there are two subtle differences. First, 77 faces less risk of being a set when 99 is already in the hand, since the hands don't directly interfere (77 and TT vs 99 and TT are completely different matchups). Second, 77's OESD boards are lower (5-6-7, 6-7-8) versus 99's OESD boards (7-8-9, 8-9-T), meaning 77's danger boards rarely coincide with boards that threaten TT from the straight direction. TT can play 9-high boards cautiously against 99 but play 6-high and 7-high boards more confidently against 77 since those boards don't contain tens in straight combinations as directly.
What is the 5-6-7 flop scenario — TT vs 77's most explosive board?
The 5-6-7 flop is the most equity-shifting board in TT vs 77 — 77 flops a set (requiring one of the two remaining sevens) on a board that is maximally connected. On 5-6-7, the board already contains the makings of multiple straight possibilities: 4-5-6-7-8 (needing a 4 or 8), 3-4-5-6-7 (needing a 3 or 4), 5-6-7-8-9 (needing an 8 or 9). When 77 flops a set on 5-6-7, it has set equity plus OESD-adjacent potential, dropping TT's equity to approximately 68.3%. Compare this to 8-x-x boards vs TT: those reduce TT's equity to 71.4%, but 5-6-7 with a set is even more extreme because the board connectivity is maximal.
Should 77 ever fold preflop against TT in a 3-bet pot?
77 against TT in a 3-bet pot is a marginal but typically a fold or a cold-call situation, not a 4-bet bluff candidate. In a 3-bet pot, pot odds shrink and the set-mining math becomes more challenging: 77 needs roughly 7:1 implied odds to justify set-mining profitably, and in a 3-bet pot the SPR (stack-to-pot ratio) may be too low to realize those implied odds. Against a known TT, 77 should call preflop only when: (1) stacks are deep (100BB+), (2) opponent is likely to stack off with an overpair, and (3) pot odds allow sufficient implied return when the set lands. In many 3-bet pot scenarios, 77 should fold to preserve equity for better spots.
How does TT vs 77 fit into the full pair-vs-pair equity spectrum?
TT vs 77 (81.8%) is 0.3 pp above TT vs 99 (81.5%) and 0.1 pp above TT vs 88 (81.7%), reflecting the progressive increase in TT's equity as the lower pair's rank decreases. The pattern is consistent: as the pair gap grows, the lower pair's secondary equity (straight draws, connected board combinations involving both pairs) shrinks, and TT's clean domination increases. TT vs 66 (81.9%) and TT vs 55 (82.0%) continue this trend. The full reference table below shows all pair-vs-pair matchups in the equity spectrum.
