it appears that i'm still not even close to understanding this couldn't find a thread explaining this, so i ask again, sorry. well: i know that every forehand i hit will be relatively top spinned. but when i see Berdych hit those flat bombs (not just high balls, but when he needs to just put the ball away skidding low), i don't get what i need to do. i think i never succeeded doing that, even by mistake. it's a weapon i feel i need but still just haven't figured out correctly. my coach told me to go forward with the stroke motion, etc. well, all i know is that he could hit those lower faster balls at me that skid fast and low, whenever he chooses to. i'm still far from getting the "trick". but i thought maybe some of you have some basic simple fundamentals i could just learn to use also while i practice by myself, to finally feel that my balls go off flatter and lower... there isn't ONE video on YT that deals with the specific flattening. and i cannot understand what to do differently even when i carefully try watching various slow motion videos. it still somehow looks the same to me. i apologize if it's a repeated question. thanks.
