Nice analysis!
Very interesting.
I love this opening. I've gotten some terrific wins with the Staunton (and plenty of losses!). I wish more people played the Dutch so I could give it a shot more often. This is another one of those openings that was considered a dangerous weapon in the 19th century, but has since been defanged thanks to tons of theory. However, for folks on my subterranean level, it's still a good try, and a lot of fun, too!
As someone who has played the Staunton Gambit both as white and as black, I would say that it is a tricky opening to play against, but it is easy to mess up as white as well.
So, what do you think about the Staunton Gambit?
