How to BH loop fast long serves

Hi, coach!

An opponent serve is fast to the corners and unpredictable. He can serve to left or right deep corner. There is no backspin on the serve, but is very fast. I try to not stand close to the table. From the right corner I can loop it. But I can not loop from the left side. When I loop from the left the ball goes to the net or goes off the table. So I just block it, but it is weak stroke, he starts  attacking. And there is no much time to swing well. And it feels that I can not find the right distance and timing to loop it. 

1) How must be the angle of the racket during looping? Open? Closed? 

2) Do I need to swing as much as possible?

3) Do I need to brush as much as possible?

Hi Ardak,

I think the main thing on the Backhand side is to keep the stroke short but move your racket through very fast and vertical with a brushing action.  Since the ball is going so fast it will feel like it was more backspin.  IT will go into the rubber and come out quickly so that is why you have to brush up quickly.
