Difficult conversation about puzzles such as this one (10)

I believe the answer is:

crosswords

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

'difficult conversation about puzzles such' is the definition.
I can't judge whether this defines the answer.

'this one' is the wordplay.
'this' becomes 'crossword' (the crossword currently being solved is an example).
'one' becomes 's' (I can't explain this - if you can you should believe this answer much more).
'crossword'+'s'='CROSSWORDS'

'as' acts as a link.

Can you help me to learn more?

(Another definition for crosswords that I've seen is " which call for solutions".)

I've seen this clue in The Irish Times.
