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

'opening' is the definition.
(I know that wicket is a type of opening)

I can't explain the rest of the clue.

(Other definitions for wicket that I've seen before include "Three stumps plus a crosspiece" , "Small door or gate" , "Stumps and bails construction - success for a bowler" , "One of the 21 acrosses" , "Means of access" .)

I've seen this clue in The Independent.
