How do you improve your memory in chess?
Do you ever practice drills with other people, for example tell them what line you want to go over?
I've tried to learn gambits, even just for fun. The problem being no one has ever accepted or gone down the line of play I want them to on any of the casual games I go onto.
I watch youtubers and they will say "Ok Stafford gambit time" and it goes near enough exactly how they want it to, and they will have these games multiple times a day according to their videos, and against really good players.
You improve your memory by going over lines in a study, and of course, trying to understand the point of each move.
I've never studied an opening from a book or course, but I do leverage Youtube (for someone to explain the ideas) and the lichess opening explorer, which allows you to review games played by players of all rating ranges (not just masters) so you can see what lines lead to common traps or mistakes.
As for drilling them, I guess you just build up this experience over time via blitz games.
Don't expect people to play main line theory though until probably closer to 1400-1500 and up.
I didnt start really preparing openings properly until I was around 1800-2000.
You can also put up a post in the Openings sub forum to seek players of a certain rating range who are willing to play certain openings, and that you can return the favour by playing their openings as well. eg. "1000 Rated Player seeking Opponent (+/- 150 points) to drill X opening"
As for your "Stafford Gambit time" - the thing with Eric Rosen is he is basically the 'Top G' for that specific opening. He has studied most variations. So even if it looks like he knows exactly what to do against his opponents move - its not because he's memorised only one line and his opponent goes down it perfectly, it's because he knows maybe 10 deviations from the main line and whichever side-move his opponent plays, he's also prepared for that too - so he can play it instantly.
Eric is a great guy and he actually gave me a private 1:1 lesson on the Stafford. I've played it ever since (in blitz - it's a bit too dubious for longer play).
