'losing player had some luck?' is the definition.
I don't know anything about this answer so I cannot tell whether this works.

'juncture at which' is the wordplay.
'juncture' becomes 'point' (I've seen this in another clue).
'at' means one lot of letters go next to another (I've seen this in other clues).
'which' becomes 'break' (I can't explain this - if you can you should give a lot more credence to this answer).
'point' after 'break' is 'BREAK POINT'.

'the' is the link.
