Heads for loss, if doubling one's stake in the pools (5)
I believe the answer is:
lidos
'the pools' is the definition.
The answer and definition can be both man-made objects as well as being plural nouns.
Maybe there's an association between them I don't understand?
'heads for loss if doubling one's stake' is the wordplay.
'heads for' says to take the initial letters.
The first letters of 'loss if doubling ones stake' is 'LIDOS'.
'in' acts as a link.
Can you help me to learn more?
(Other definitions for lidos that I've seen before include "Open-air swimming pools" , "leisure facilities" , "Solid (anag) -- pools" , "bathing beaches" , "which swimmers may use" .)
