Clever plans to start games collapse (10)

I believe the answer is:

stratagems

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

'clever plans' is the definition.
'stratagems' can be an answer for 'plans' (stratagem is a kind of plan). I am unsure of the 'clever' bit.

'start games collapse' is the wordplay.
'collapse' indicates anagramming the letters.
'start'+'games'='startgames'
'startgames' anagrammed gives 'STRATAGEMS'.

'to' is the link.

Can you help me to learn more?

(Other definitions for stratagems that I've seen before include "Manoeuvres" , "Plans" .)

I've seen this clue in the Sydney Morning Herald.
