66 vs 22 Odds: Pocket Sixes vs Pocket Twos
Last updated: May 27, 2026
Pocket Sixes (66) wins 81.9% of the time against Pocket Twos (22) preflop. 22 wins 16.4% with ties at 1.7%. This is 66's highest equity against any lower pocket pair — the four-rank gap between sixes and twos, combined with 22's status as the most board-disconnected hand in poker, pushes 66's win rate to its ceiling among low-pair domination matchups. Deuce boards are the rarest flop type, and deuces appear in only one possible straight (the wheel), leaving 22 with almost zero secondary equity beyond flopping a set.
The Exact Number: 81.9% vs 16.4%
66's 65.5-point margin over 22 is the largest 66 achieves against any lower pair. The 1.7% tie rate is constant across all 66 vs lower-pair matchups because low pair splits depend on board-pairing and full-board scenarios that are rank-independent at this level. This matchup is the clearest expression of low-pair domination: 22 has almost nowhere to turn for secondary equity.

1.7%
22's 16.4% equity is the lowest any pair achieves against 66. Its distribution: approximately 10.4% from set-flop scenarios, ~1.5% from the wheel gutshot on A-3-4 boards, ~0.8% from runner-runner boats and quads, and ~3.7% from miscellaneous board-play and tie scenarios. The near-absence of straight-draw equity makes 22's profile uniquely set-concentrated.
Does the Suit Matter?
Suit combinations affect 66 vs 22 by approximately 0.4 percentage points. 22's primary equity driver (set outs) is completely suit-independent — the variation comes only from flush draw possibilities when 22 shares a suit with a six. The 1.7% tie rate is constant across all suit configurations.

Post-Flop: The 6-2-x Cooler and Deuce Board Analysis
Post-flop in 66 vs 22, the scenario analysis is simple: either 22 flops a set (and becomes a heavy favourite) or it does not (and 66 holds overwhelming equity). Deuce boards are the rarest flop type, so even when 22 does flop its set on a 2-x-x board, the board type itself is unusual. The 6-2-x set-over-set is the definitive cooler for this matchup.

22's Maximum Board Disconnection — and Why It Matters
Every pocket pair can make exactly as many sets as every other pocket pair (11.8% flop rate, 2 outs). The difference between low pairs in equity matchups comes from secondary equity sources — straight draws, flush draw connectivity, and board texture interaction. 22 is at the extreme low end of all these measures.
Deuces appear in only one straight: A-2-3-4-5 (the wheel). Compare: fives appear in A-2-3-4-5 and 3-4-5-6-7; sixes appear in A-2-3-4-5 (no), 2-3-4-5-6, 3-4-5-6-7, 4-5-6-7-8 — three straights. Threes appear in A-2-3-4-5 and 2-3-4-5-6 — two straights. 22 is uniquely limited. This single-straight limitation means that on most boards, 22 has no path to a straight draw that can supplement its set equity. Six-high boards (6-x-x) appear regularly throughout a poker session because sixes feature in multiple straights and common mid-low board textures. Deuce boards are genuinely rare events — and when they appear without a set for 22, 22 is simply an underpair with nowhere to improve.

Frequently Asked Questions
What are the exact 66 vs 22 preflop odds?
Pocket Sixes (66) win 81.9% of the time against Pocket Twos (22) preflop. 22 wins 16.4% and ties account for 1.7%. This is 66's highest equity against any lower pocket pair — the four-rank gap between sixes and twos, combined with 22's maximum board disconnection, pushes 66's win rate to its ceiling in low-pair domination matchups. 22 flops a set approximately 11.8% of the time; when it does, 22 becomes roughly an 88% favourite from that point.
Why does 66 win more against 22 than against 33, 44, or 55?
66 wins 81.5% vs 55, 81.7% vs 44, 81.8% vs 33, and 81.9% vs 22 — a consistent upward trend as the opponent pair decreases. The reason: lower pairs connect to fewer board textures. 55 shares some board connectivity with 66 via 4-5-6 and 5-6-7 combinations; 44 slightly less so; 33 connects mainly to A-2-3 wheel boards; 22 has almost no secondary equity sources beyond its set outs. Deuces appear in the fewest straight combinations of any rank (only A-2-3-4-5), making 22 the most board-disconnected hand in poker. This maximizes 66's equity by eliminating nearly all of 22's secondary winning paths.
Are deuce boards rare, and why does that matter for 22?
Yes — deuce-high boards (2-x-x flops where a deuce is the highest card) are the rarest flop type in poker. When 22 does not flop a set, it holds a pair of twos on a board that will almost always feature higher-ranked cards. This means 22 is an underpair on virtually every non-set flop — there are almost no boards where twos are an overpair or near-overpair to the community cards. Against 66, this is irrelevant to direct equity (the board doesn't change the preflop calculation), but it explains why 22's secondary equity is lower than other low pairs: deuce boards that would provide set-type opportunities with flush/straight continuations are extremely rare.
What is the 6-2-x set-over-set scenario?
On a 6-2-x flop, both 66 and 22 have flopped sets simultaneously — 66 has top set (three sixes) and 22 has bottom set (three twos). 66 wins approximately 85% from this point. 22 can only win by making four twos (quads) or running out a full house of twos-over-sixes that beats 66's full house of sixes-over-twos. Both players typically commit all chips on this board — it is a set-over-set cooler where 66 is dominant. Set-over-set requires both players to flop their respective sets simultaneously, which occurs approximately 0.3% of the time given both are holding pocket pairs.
Does 22 ever benefit from wheel boards against 66?
22 has the most limited wheel connectivity of any pocket pair. The only straight containing a two is A-2-3-4-5 (the wheel). On A-3-4 flop, 22 picks up a gutshot — specifically needing a 5 to complete A-2-3-4-5 with a 2 in hand. This is a real (if minor) equity source. However, 22 cannot use a wheel board to gain straight equity the way 55 can (55 makes the top card of the wheel). Even on the most wheel-relevant flop (A-3-4), 22 gains only modest equity (~2–3% above its baseline) from the gutshot draw. 66 remains a comfortable overpair throughout.
What are the implied odds for 22 set-mining vs 66?
22 set-mining vs 66 follows the standard small pocket pair implied odds calculation. 22 must call a raise and extract enough chips when it flops a set (~11.8%) to compensate for the 88.2% miss rate. The required ratio is approximately 7:1. Against 66, which holds an overpair on low boards and is highly likely to continue betting through the hand, 22's implied odds are strong — 66's stack is at risk any time 22 flops its set. The risk: 22 flops its set on 2-x-x boards, and if 66 correctly reads the 2-high board as dangerous and checks back (or bets small), 22's realized payoff diminishes. In practice, 66 usually continues strongly on 2-high boards as an overpair.
How does 66 vs 22 compare to the full pair-vs-pair equity spectrum?
66 vs 22 (81.9%) is among the higher-equity low-pair domination matchups, matching KK vs QQ (81.9%) in percentage. The full spectrum runs from AA vs KK (82.4%) at the top to adjacent low pairs like 44 vs 33 and 33 vs 22 (both 81.5%) at the lower end of the cluster. 66 vs 22 reaching 81.9% despite being a low-pair matchup — not a premium pair matchup — reflects that 22's maximum disconnection from board textures produces equity similar to premium pair matchups where the lower pair is limited by shared card interactions.
