Most players when given this
problem will say take two finesses.
This is nearly correct, there is, however, a slight wrinkle.
If you finesse the nine and it loses to the queen (say) then you should next cash a high honour in the dummy in case East has QJ doubleton,
then you take the second finesse.
It is not correct to cash a high honour first, which gains if there is a singleton Q or J offside, but loses if both the queen and jack are onside.
Thanks to Alan Mould for this
problem.
