There may be a chance to draw them (4)
I believe the answer is:
lots
'there may be a chance' is the definition.
I can't judge whether this defines the answer.
'draw them' is the wordplay.
'draw' becomes 'lot' (synonyms).
'them' becomes 's' (I can't justify this - if you can you should give a lot more credence to this answer).
'lot'+'s'='LOTS'
'to' acts as a link.
Can you help me to learn more?
(Other definitions for lots that I've seen before include "Loads" , "Great quantities" , "Large numbers at auction" , "Something to draw" , "Units sold at auctions - plenty of them" .)
