The Goon Squad agrees.
The base BH serve (especially his underspin one) is started with a motion that brings the hand all the way up to the face, then releases the ball right there... ball does not rise 15 cm or even ONE cm vertical from the hand... but it DOES travel 10-15 cm BACKWARDS after leaving the hand... and OOOHHH... his now free hand travels downward with the ball all the way to impact and nearly hides the ball the entire time... never removes hand from the area between the ball and the receiver... nor even attempts to remove the hand from this space.
Yup. His toss makes that BH serve an illegal serve if the umpire has even a minimum of training and attention to detail.
But what the heck, who plays matches with real umpires or trained ones or motivated/attentive ones? That stuff is for loser amateurs. [/END SARCASM]

I never thought I could learn so much how to do an illegal serve on BH from just one vid. So many of us have been clamoring for more BH serves to level the playing field with hidden FH serves... guess we all gotta drink a large cup of STFU on that one and think again...
