Generous hand bringing colour to Her Majesty's cheeks? (5,5)
I believe the answer is:
royal flush
'colour to her majesty's cheeks?' is the definition.
I can't tell whether this defines the answer.
'generous hand' is the wordplay.
'generous' becomes 'royal' (I am not sure about this - if you are sure you should believe this answer much more).
'hand' becomes 'flush' (poker).
'royal'+'flush'='ROYAL FLUSH'
'bringing' is the link.
Can you help me to learn more?
(Other definitions for royal flush that I've seen before include "winning hand?" , "Top hand" , "Good hand" , "embarrassment at the palace?" , "Great hand" .)
