When engines do not work… (+ Video)

Hello everyone. Some friends told me they enjoyed my post about fortresses, and asked me to do a new work about it. That’s why today I bring a couple of new examples and analysis about this interesting theme. I would like to make emphasis in the fact that engines have many problems to evaluate these positions I am bringing today (as in the ones from the previous post). I think they give too much importance to the material. It seems like fortresses is not where they shine. J

If you didn’t read my previous post, this is like my own definition about fortresses: It’s when a side is in obvious material disadvantage, but can find a position for his pieces where his opponent doesn’t have a way to make any real progress. It happens mostly in endgames, but it could also happen (rarely) in some middlegame.

You can find these and other fortresses explained in this video in my channel.

You are welcome to leave a comment with some other kind of fortresses.
