How is 7 Cards Stud being played?

Hi everybody I am new to 7 Cards Stud and I want to know about the game more better.

For example I sit to the left of the dealer.

Player A is the dealer
Player B is me
Player C
Player D

As you can see player A dealt to me first and so on...

Player A (XX Qd)
Player B (XX Kh)
Player C (XX 10c)
Player D (xx 8d)

Player D bring in
player A call
player B call
Player D call

I know at this point player A have to dealt the next card to player B & 4th streets are...

Player A (XX Qd 9s)
Player B (XX Kh 5c)
Player C (XX 10c 4s)
Player D (xx 8d 9h)

This is where I got confused if everybody check; player A suppose to dealt the next card to player B or to the player with the best hand show at the moment and so for 5th, 6th and 7th streets?

Also can the dealer rotate around the table or it have to stay it in one position like can player A be the dealer throughout the game entirely?

I hope you guy can answer my question thank you very much

After the first betting round, another upcard is dealt to each player (after a burn card, and starting at the dealer's left as will all subsequent rounds), followed by a second betting round beginning with the player whose upcards make the best poker hand.

I think I get what you are asking. When physically dealing the cards, which players receives the next card on each street? I wasn't sure, so I had to consult wiki.

"After the first betting round, another upcard is dealt to each player (after a burn card, and starting at the dealer's left as will all subsequent rounds)"

Seems reasonable to me. So whichever seat is the dealer, starts dealing the new street to the first player to their left that is still in.

I sent you a link to a site that will send you a series of free vids. re:Stud poker.
Also, if you just google search 'stud poker strategy' you'll find a ton of stuff. Not sure if there's much Stud poker stuff here on CC? (anyone have any links to it?)

Thank you so much. I really appreciated what you've sent to me.
