Interesting fold by a pretty solid player on Stars
 

I was recently fairly deep in a $10 NLHE event on stars when this very interesting scenario unfolded. A notable player on stars, ~US&CO~, was UTG and made a standard 3xbb raise. He had been playing fairly tight at the time and had a middle of the pack stack like myself at the moment. We had played each other previously he had seen I was TAG. After his raise UTG I made a mini-reraise by hitting the raise button on accident instead of the fold button with rags. It folds around back to ~US&CO~ and he thinks for a moment and shockingly folds. I see this kind of mini-reraise by people with premium hands like QQ,KK,AA and perhaps he put me on that. My questions are
1)does this kind of move have a name if its considered a bluff?
2)Is this an effective weapon and if it is I would assume it should only be used against very observant weak/tight players?
3)Has anyone ever used this move on purpose, unlike my scenario?

PS:Any other thoughts would be welcome as well

No

It was a bad fold by him and don't expect it to be the norm.

My guess is, yours wasn't the only misclick in the hand.

He can basically call with any two here given the odds. You misclicked he misclicked.
