    Not sure if the hA is right. On a bad day you might not have an entry.

    Double dummy analysis perhaps for the lead although I am not sure what sort of bias you get for the hA lead.

    There is another bias on this hand, given the singleton King will allow the King to be captured by perfect vision when a finesse would otherwise be taken. Also exactly specifying EW hands is problematic.

    However... a spade lead seems to be an overwhelming favourite by about 0.5 tricks over the next best (HQ) (or 13% better at IMPS), which in turn was ~0.3 tricks better than the HA or Hx.

    I switched the EW hands so the strong hand was declarer (but kept the HK with declarer). Now the HA and spade lead are lineball (spade is ~3% better at IMPS) and about 0.6 tricks better than the other heart leads.
    I checked for the singleton K impact by switching a small spade to diamonds. This just made the spade lead even better!
