Today, we are delighted to introduce a new lichess blogger, MoralIntentions. You probably already know him for his helpful forum posts, his thousands of lichess games, and of course the amazing chess alphabet!

You can learn more from certain games than from others. That's why I've looked for a typical lichess game that many players can learn from. I will discuss the game between Geol020 and german11, that can be found at http://lichess.org/BYlUzns8.
