In fact you have menace cards in all four suits, but if opp's guards are all well placed (i.e. over the menaces as pointed out by Cyberyeti and The_Badger) the U of Clyde Love's BLUE is wrong for any squeeze.
If you allow the heart menace to be duplicated, i.e.
♥Kxxx with South, there is a 100% line, as U is true for squeezes including the duplicated menace.
Cash
♠AQ and
♥AK.
1. If one of the majors splits, you are home.
2. Otherwise if one opponent guards both majors, cash
♣KAQ (discarding a heart) and
♦AK squeezing him in the majors.
3. If no major splits and each opponent guards one of them, cash
♥Q,
♦AK and
♠KJ (discarding dummy's red cards) squeezing the opponent holding
♣Jxxx (if any).
To execute the appropriate squeeze declarer has to give up the heart menace under the control, keeping the heart menace over the control. Therefore it is essential to find out who controls the hearts.
