you can't get a stroke on a second attempt, so the answer is let.
Interesting, I never knew that!
I've seen it plenty of times before to hold the swing, let the opponent clatter into the racquet/ball/player & have a stroke awarded. You can really 'manufacture' an easy stroke from that situation, whether its ethically right or wrong is a whole other arguement.
I would have called a stroke on that, however, I stand corrected for not knowing the rules properly!
