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 it can be defined by this definition.
'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' is the link.
Can you help me to learn more?
(Another definition for egg-white that I've seen is " Albumen".)
