The cricket team were dismissed at full speed (3-3)
I believe the answer is:
all-out
'at full speed' is the definition.
(thesaurus)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for all-out that I've seen before include "Using maximum energy - no one at home?" , "Using every resource" , "Complete" , "Nobody home, at top speed" , "Using full strength or energy - nobody home?" .)
