I need to know which one is the correct forehand grip. As you can see, in the first image the area beneath the thumb is not pressed completely(only a little bit against the handle most of the time(not even during the tightening of the grip before contact) and the bottom leftmost palm area is also a bit free unlike in the second grip where both of them are touching the racket. If you need to know more I'm happy to help! (I've verified the grip is correct from the other angle, makes a sharp v and is on the same line as the racket head. So which is the forehand grip? Here's a small video too with better views 'imgur.com/a/gFcI0g7'
