yes, he is a good coach, he knows that he needs to cheer his student !
his name is Hidetoshi OYA (大矢 秀俊), there is plenty of videos of him on YouTube, and you can see his stats on ITTF site for example.
yeh the swipe push is quite new for me, i'm trying to follow the advices given in the WRM video by the Chinese coach Meng. it seems I have a good feeling for it ! i was surprised i made some really good shots and so was OYA. But maybe its just beginner's luck. I need to practice more and see if i'm able to do it under pressure during a match.
If you see the WRM video, MENG explains that the good thing about this receive is that it can work against whatever incoming spin, and you can aim any side of the table, but it helps if the serve is low, the receive is more tricky to do against a higher ball (better to do a chiquita, FH flick, stop or a normal push)
