How the clue works
The definition is when playing well, meaning performing at your peak. "Man goes" gives you MANGOES, "wild" tells you to anagram it, and "securing ace" means you tuck ONE (ace, in cards) inside those letters before you do — shuffle the whole lot together and out comes your answer.
