Poor Keir's adrift, regularly gambled (6,2)

I believe the answer is:

risked it

I'm a little stuck... Click here to teach me more about this clue!

'gambled' is the definition.
I don't know anything about this answer so I can't tell whether it can be defined by this definition.

'poor keir's adrift regularly' is the wordplay.
'poor' indicates an anagram.
'regularly' means one should take alternating letters (regularly take one letter, leave next etc.).
The alternating letters of 'adrift' are 'dit'.
'keirs' is an anagram of 'riske'.
'riske'+'dit'='RISKED IT'

Can you help me to learn more?
