South American guerrilla leader’s second game (5)
I believe the answer is:
chess
'game' is the definition.
(board game)
'south american guerrilla leader's second' is the wordplay.
I cannot really understand how this works, but
'south' could be 's' (abbreviation) and 's' is found in the answer.
'guerrilla' could be 'che' (guerrilla fighter Che Guevara) and 'che' is found in the answer.
'second' could be 's' (common abbreviation) and 's' is found in the answer.
No letters remain.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for chess that I've seen before include "Board game for two players" , "Game with kings and queens" , "show" , "A game of skill" , "Pure-skill board game" .)
