TT vs a 4-betting range: Equity & Strategy

Pocket Tens (TT) has 42.2% equity all-in preflop against a 4-betting range — 42 combos, 3.2% of all starting hands. It wins 42.0% of runouts outright, loses 57.6% and chops 0.4%. These are exact figures from full board enumeration against every unblocked combo in the range, not a simulation.

The range this is computed against

Four-betting is the tightest voluntary action in preflop poker. The standard construction is QQ+ and AK for value plus a token pair of blocker bluffs — A5s and A4s, which remove combos of AA and AK from the opponent's continuing range and still flop wheel and nut-flush draws when called. About 3% of hands.

4-bet — 42 combos, 3.2% of all starting hands: AA, KK, QQ, AKs, A5s, A4s, AKo

After card removal, 42 of those 42 combos are still available (0 are blocked by the cards TT holds). TT is ahead of 24 and behind 18.

Easiest parts of the range for TT

Put TT up against a 4-betting range — 42 combos, 3.2% of all hands — and the exact answer is 42.2% equity: 42.0% outright wins, 57.6% losses and 0.4% chops. None of the range's combos share a card with TT, so all 42 of them are live in this calculation. You are ahead of only 24 of the 42 combos still live (57%) — the rest of the range is level with or in front of you, which is why the figure sits below even money.

Where does the range come from? Four-betting is the tightest voluntary action in preflop poker. The standard construction is QQ+ and AK for value plus a token pair of blocker bluffs — A5s and A4s, which remove combos of AA and AK from the opponent's continuing range and still flop wheel and nut-flush draws when called. About 3% of hands. Broken down hand by hand, TT does worst against QQ (18.4%), KK (18.9%) and AA (19.3%) and best against A4s (67.0%), A5s (67.0%) and AKo (56.9%). Across the whole range TT's equity swings from 18.4% at the bottom to 67.0% at the top — the single 42.2% headline is the combo-weighted average of all of it.

A 4-bet is the tightest action in preflop poker, and 42.2% reflects that: TT is behind, and against a range this narrow the only sane options are 5-bet-jam with the right blockers or fold. There is no flat-and-outplay-them line against 3.2% of hands with the stacks a 4-bet creates.

What hands are in a 4-betting range?

7 hand classes and 42 combos — 3.2% of the 1,326 possible starting hands. By combo count it is 43% pocket pairs (3 pairs, 18 combos), 29% suited hands (3 classes, 12 combos) and 29% offsuit hands (1 classes, 12 combos). That shape is why TT runs at 42.2% against it rather than against a random hand.

Does TT do better against a wider or a tighter range?

Wider, almost always. TT has 68.6% equity against a loose-passive calling range (50.5% of hands) but 42.2% against a 4-betting range (3.2%). Equity against a range is mostly a question of how many weak hands the range still contains — which is why the same holding can be a monster against a button open and a fold against a 4-bet.
