TT vs 66 Odds: Pocket Tens vs Pocket Sixes
Last updated: May 27, 2026
Pocket Tens (TT) wins 81.9% of the time against Pocket Sixes (66) preflop. 66 wins 16.4% with ties at 1.7%. This is one of TT's cleanest domination matchups — 66 is a pure set-mining hand against TT, with nearly all its equity derived from flopping one of the two remaining sixes. TT benefits from an overwhelming edge on all high-card boards: roughly 70% of all flops feature no six and no low connected board threatening TT's overpair position.
The Exact Number: 81.9% vs 16.4%
TT's 65.5-point advantage is the highest TT achieves among its medium-pair matchups (TT vs 99: 81.5%, TT vs 88: 81.7%, TT vs 77: 81.8%, TT vs 66: 81.9%). The 1.7% tie rate is stable — identical to TT vs 77 — because the tie-producing straight combinations for 66 vs TT (boards like 6-7-8-9-T where both hands make the same straight) are similarly rare to those for 77 vs TT.

66's 16.4% equity is the most concentrated in a single source of all TT's pair matchups: ~10.4% from flopping a set, ~2.3% from low connected draw boards, ~0.8% from runner-runner scenarios, and ~2.9% from miscellaneous board-play situations. The set-flopping scenario is overwhelmingly 66's most important equity mechanism.
Does the Suit Matter?
Suit combinations affect TT vs 66 by approximately 0.4 percentage points. The flush draw advantage for 66 when sharing a suit with a ten is structurally real but strategically minimal — 66's flush draw on suited boards rarely combines with meaningful secondary equity (no straight draw boards to pair with), making the 0.4 pp swing primarily theoretical rather than strategically impactful.

Post-Flop: Why TT Dominates on ~70% of All Boards
Against 99, TT faces meaningful post-flop complexity on 7-8-9 and 8-9-T boards. Against 66, TT benefits from the simplification that virtually all boards above six-high are unambiguous overpair situations for TT. 66 cannot threaten TT via straight draws on nine-high, ten-high, or broadway boards — its straight completions all require low connected combinations far removed from TT's range.

66 as a Pure Set-Mine: The Math Behind the Hand
The set-mining calculation for 66 vs TT is clean and direct. 66 flops a set approximately 11.8% of the time. When it does, 66 wins roughly 88.5% of subsequent hands. This means 66's set-flopping equity contribution is approximately 11.8% × 88.5% = ~10.4%. Add 6% for other equity sources and you arrive at 66's total ~16.4% equity.
The key implication: 66 is profitable to set-mine against TT only when implied odds are sufficient. Standard set-mining requires roughly 7:1 implied odds — you need to win at least 7x the preflop investment when you hit your set. Against TT (which is likely to stack off with an overpair on 6-high boards), 66 typically meets this threshold when 100BB deep or deeper. In shallow-stack scenarios or 3-bet pots with reduced SPR, 66's set-mining becomes marginal or unprofitable.
66 equity sources vs TT
- Flop a set of sixes (11.8%) × win from there (88.5%)~10.4%
- Low connected board draws (4-5-6, 3-4-6, 5-6-7)~2.3%
- Runner-runner quads or boats~0.8%
- Board-play ties and miscellaneous runouts~2.9%

Every pocket pair domination matchup in one place. These numbers represent the standard baseline (no suit overlap) computed from full equity simulations.
TT vs 66 (81.9%) is TT's highest equity against a medium pair — equal to KK vs QQ (81.9%) and AA vs QQ (81.9%). The pattern across all pair-vs-pair matchups confirms the set-out mechanism: favourite equity ranges from 79.3% (KK vs JJ, partial connectivity) to 82.4% (AA vs KK and KK vs 66, cleanest dominations), with TT vs 66 sitting at the upper bound for TT's matchups.

Frequently Asked Questions
What are the exact TT vs 66 preflop odds?
Pocket Tens (TT) win 81.9% of the time against Pocket Sixes (66) preflop. 66 wins 16.4% and ties account for 1.7%. This is one of TT's cleanest domination matchups among lower pairs — the four-rank gap means 66's straight draw connectivity to boards involving tens is minimal. 66 flops a set approximately 11.8% of the time; when it does, 66 becomes roughly an 88.5% favourite. Outside set-flopping scenarios, 66 has almost no meaningful equity versus TT — making this the purest set-mining scenario in TT's matchup catalog.
Why is 66 a pure set-mining hand against TT?
66 is a pure set-mining hand against TT because its secondary equity sources (straight draws, board-play equity) are minimal. To complete a straight involving a six, the board needs cards like 3-4-5-7-8 or 4-5-7-8-9 — these low connected boards are genuinely threatening when 66 flops a set, but the probability of these boards appearing is far lower than the probability of high boards (J-Q-K, Q-K-A, K-A-J) where TT has an uncontested overpair. By contrast, 99 against TT has meaningful secondary equity from boards containing 7-8-9-T combinations. 66 lacks this — its straight draw boards (3-4-5, 4-5-7) are well below the ten's range. This means 66's strategy collapses into a binary: flop a set and win, miss the set and lose.
What percentage of flops does TT dominate completely against 66?
TT has an uncontested overpair advantage on approximately 70% of all flops against 66. Any flop with no six and no six-connecting straight draw board gives TT a clean overpair with 66 having only runner-runner or backdoor equity. Specifically: any board featuring cards 7 through ace with no six gives TT a dominant position. Nine-high boards (9-x-x with no 6), ten-high boards, jack-high, queen-high, king-high, and ace-high boards are all unambiguously favorable for TT. 66's meaningful equity is concentrated in six-high boards (set scenarios) and low connected boards (4-5-6, 3-4-6, 5-6-7, 4-5-7) — roughly 20-25% of all flop textures.
How does the suited advantage compare between TT vs 66 and TT vs 99?
In TT vs 99, when 99 shares a suit with a ten, it gains approximately 0.4 pp in equity due to flush draw potential. The same suit overlap in TT vs 66 produces approximately the same 0.4 pp gain — but the strategic significance is different. Against TT, 99's flush draw can combine with straight draw boards to create meaningful multi-draw scenarios. Against TT, 66's flush draw rarely combines with any other equity source on the same board — 66 doesn't threaten broadway straights and its low flush draws typically arise on boards where it has no set. The result: 66's suit advantage is numerically similar but practically less important than 99's suit advantage.
What should TT do on six-high boards post-flop?
On 6-x-x boards, TT is a substantial overpair and should bet for value — but must be alert to set danger. If 66 has flopped a set (occurring 11.8% of the time a six appears), TT is an 11.5% underdog despite holding an overpair. The correct TT approach on 6-x-x boards: bet strongly as an overpair (you have legitimate value), but fold to a large check-raise from 66. Check-raises on 6-high boards are rare as pure bluffs from competent players — they almost exclusively represent sets. Unlike 9-high or 8-high boards (where opponents might check-raise with straight draws), 6-high boards offer fewer plausible draw combinations, making the check-raise a near-certain set indicator.
What is the set-over-set scenario for TT vs 66?
On T-6-x flops, both TT and 66 have flopped sets simultaneously. TT has top set (three tens) and 66 has middle set (three sixes). TT wins 85.8% from this point — 66's only paths to victory are quads (four sixes) or a running board that creates a higher full house for 66 than TT. Both players will typically commit all chips on T-6-x — a classic cooler — with TT an 85.8% favourite. The T-6-x set-over-set is less common than T-9-x or T-8-x set-over-set scenarios because 6 appears in fewer ranges and call less frequently, but when it occurs it plays identically to any other set-over-set structure.
How does TT vs 66 compare to TT vs 77 and TT vs 88 in equity?
TT vs 66 (81.9%) continues the progressive equity increase: TT vs 99 (81.5%), TT vs 88 (81.7%), TT vs 77 (81.8%), TT vs 66 (81.9%). Each step down in the lower pair's rank adds 0.1–0.2 pp to TT's equity because the lower pair's secondary board coverage shrinks. 66's secondary equity from straight draws is the smallest among this group — sixes connect to fewer boards that also involve tens or high cards — making TT vs 66 the cleanest domination in TT's medium-pair matchup set. The pattern continues with TT vs 55 and TT vs 44, which would show further (smaller) equity increases.
