Chip, software, joint effort (8,4)

Ross

I believe the answer is:

approach shot

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

'chip software' is the definition.
The answer and definition can be both acts as well as being singular nouns.
Perhaps you can see a link between them that I don't see?

'joint effort' is the wordplay.
'joint' becomes 'approach' (I can't explain this - if you can you should believe this answer much more).
'effort' becomes 'shot' (both can mean an attempt).
'approach'+'shot'='APPROACH SHOT'

Can you help me to learn more?

(Another definition for approach shot that I've seen is " Made by golfers towards the green".)
