You can use ...d5 against the normal, or delayed Alapin. It is one of the most reliable ways to play as Black. Just remember NOT playing an early ...Bg7 in the delayed form (it is far from being a bad move, but it unnecessarily complicates things).
These early ...g6 systems are also fine for stuff like the Morra gambit.
You can find thousands of master games starting from these positions.
As of about the past 6 months I have started playing a Sicilian Hyperaccelerated Dragon. With this, I seem to be struggling to know what to do against the Alapin which makes 0 sense as I quite literally play the Alapin and understand the theory as white. Now, my win rate as black is actually the best out of any other line on move 2, but that does not change the fact that I feel lost out the opening. Another thing I want to note is my win rate is actually terrible in the DELAYED Alapin, due to the fact I have already played g6. I was wondering what some of your suggestions are, I have been googling relentlessly, but there are far too many lines, and something such as knowing what the best win % lines are would be greatly appreciated. Below I will attach a few different ideas I have been employing, would love all of your thoughts.
