Having one, is a player red-handed? (5)
I believe the answer is:
flush
'red-handed?' is the definition.
Both the definition and answer are adjectives.
Perhaps you can see a link between them that I don't see?
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for flush that I've seen before include "winning hand at poker" , "Become red and hot" , "Rush of blood" , "Look ashamed < , maybe even promising hand" , "Pull the chain - rush of emotion - good poker hand - having plenty of money" .)
