@XaeL I don't understand 'poor at best' ?  This video is made especially for TF players so I guess B2B T-spin openings are good

most of these openings are poor at best.

ouh O_o well that's a grammatical error.. but to change it I need to re-upload the whole video and that's a lot of time xP . Just sorry for that one~ I'm too lazy to change it 

you'll need to edit "many players have not yet use effective openings" to "many players have not yet used effective openings"

"many players have not yet used effective openings"

That is so true, even for the set ups shown in this video.
