This site has helped me significantly with remembering my opening prep, allowing me to get good positions out of the opening much more consistently even in strong tournaments such as the National High School Championships and Illinois Open.
Opening House is a really convenient way to keep your lines fresh in your memory. The site being centered specifically around prep makes it much easier to focus only on the lines you need to work on. I think a lot of other sites try to do too much, to the point where features like drilling opening prep are underdeveloped.
I think it's important for people to study openings so that you're not putting yourself at a disadvantage going into the rest of the game. Only when you know your lines well can you spend more time understanding deeper middlegame ideas. Opening House is an effective and easy way to put that prep into practice.
