my friend you don't even hit a 1hbh... but I give it to you... 'contact' might work for some people... however the 1hbh is so dependent on a good hand action (hence the thumb push), and there is no 2nd hand to help.
the footwork patterns - maybe they have to be taught to some, but to me if you have played any other sports, the patterns are fairly universal... when you are in an emergency, or have to hit an object 1 direction while your body is going another..
i can hit a 1hbh, albeit not as consistently as my 2hbh, but i can rip it (when it goes in, it's a bigger shot than my 2hbh)
i also taught myself to hit a 1hbh lefty... for the sake of being able to teach a beginner who wanted to hit a 1hbh.
and yes, it requires good "hand action" (same with the fh as well).
lol, if you played other sports... then you didn't just "automatically" learn footwork patterns... you learned them from the other sports. in general, i agree athletes will often have a large vocabulary of movement that cross over to other sports. but it's not just "automatic"... so if you play tennis as your first sport... guess what, you have to learn those footwork patterns for the first time (either formally (bailey method), or just through alot of trial and error).
similarly i "naturally" learned how to hit opposite field for my corporate softball team (even when the former baseball players - ie. "the big sluggers" on the team couldn't do it well)... ie no one taught me..... but really it was because i hit so many inside-out fh's beforehand.
side note... i can seee the thumb roll being critical in guiding the racquet face to contact,... similar to how the index finger is critical in guiding for the fh.
