Here I did a lesson for the BBO IAC club. I talk about the convention "Puppet Stayman" If you like this and are interested in more videos then check out www.bridgevid.com
What you explain makes sense. But explaining the system with that particular BBO board in view is not accurate with your explanations. I'm getting confused all the time.
There is also a convention called Muppet stayman which swaps the 3h and 3nt responses which helps if responder has 5 spades and 4 hearts.
