Learn and test any opening in hours!

See the whole post, with a step by step tutorial on how to do this, here: How to learn and test any opening in hours with LiChess Tools browser extension

## Long story short

In order to do this you need:

• a Chromium-based browser like Chrome, Brave, Kiwi and so on. (the latter also works on mobile devices while allowing browser extensions)
• installing the LiChess Tools extension in it (don't worry, it's completely free, ad free, spam free, open source, MIT licensed)
• go to the lichess.org website to the Analysis board or Study pages
• open the Opening Explorer and click on the little button on the top left side to enable Explorer Practice

Explorer Practice is exactly what it sounds like: it uses the information from the Explorer database to play the moves of the opposing side. This works for the Masters tab, for the Lichess tab (where you can select the type of game and player level range as well) and even for the Player tab, where you can train to play as or against a specific lichess player. You can even play against yourself! How cool is that?
