For example, good chess player that may be beaten by a whisker (3-5)
I believe the answer is:
egg-white
'may be beaten by a whisker' is the definition.
I don't know anything about this answer so I can't tell whether this works.
'for example good chess player' is the wordplay.
'for example' becomes 'e.g.' (short for 'exempli gratia', 'for example' in Latin).
'good' becomes 'g' (abbreviation).
'chess player' becomes 'white' (one of the two players in a game of chess).
'eg'+'g'+'white'='EGG-WHITE'
'that' acts as a link.
Can you help me to learn more?
(Another definition for egg-white that I've seen is " Albumen".)
