JJ vs a 3-bet bluffing range: Equity & Strategy

Pocket Jacks (JJ) has 71.8% equity all-in preflop against a 3-bet bluffing range — 52 combos, 3.9% of all starting hands. It wins 71.5% of runouts outright, loses 27.9% and chops 0.6%. These are exact figures from full board enumeration against every unblocked combo in the range, not a simulation.

The range this is computed against

The bluff half of a polarised 3-bet is built from hands that are too weak to flat profitably but that block the opener's best continues or flop well when called: the suited wheel aces (which block AA and AK), suited broadways like KJs and QTs, and the suited connectors. About 4% of hands.

3-bet (bluff) — 52 combos, 3.9% of all starting hands: A5s, A4s, A3s, A2s, KJs, KTs, QJs, QTs, JTs, T9s, 87s, 76s, 65s

After card removal, 46 of those 52 combos are still available (6 are blocked by the cards JJ holds). JJ is ahead of 46 and behind 0.

What hands are in a 3-bet bluffing range?

13 hand classes and 52 combos — 3.9% of the 1,326 possible starting hands. By combo count it is 0% pocket pairs (0 pairs, 0 combos), 100% suited hands (13 classes, 52 combos) and 0% offsuit hands (0 classes, 0 combos) — it contains no offsuit hands at all. That shape is why JJ runs at 71.8% against it rather than against a random hand.

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

Wider, almost always. JJ has 71.9% equity against a loose-passive calling range (50.5% of hands) but 42.0% 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.
