Retire? That might be good bet (2,2,3)

Ross

I believe the answer is:

go to bed

'retire?' is the definition.
('go to bed' can be a synonym of 'retire')

'might be good bet' is the wordplay.
'might' indicates anagramming the letters (I've seen this in other clues).
'good'+'bet'='goodbet'
'goodbet' is an anagram of 'GO TO BED'.

'that' is the link.

(Another definition for go to bed that I've seen is " Retire".)

I've seen this clue in The Times.
