LiChess: Learn from your mistakes

Now with that said, this looks quite good and really broaches chess in a modern way in terms of learning. I sure have stacks of books that I wish were just software, mostly on studying chess tactics

The future grand masters who are 10 years old atm will be far in front of the current crop of grand masters due to improvements like this.

It's interesting that even the best chess engines are still worse at analyzing openings than humans.

Is that actually the case, or perhaps humans try a lot of sub-optimal opening lines?

lichess.org and the corresponding open source project[1] are really quite something. If you're at all interested in chess or code, I recommend following it -- their great execution will inspire you.

Sub optimal from the perspective of the AI, some positions that seem easy for an AI looking 10 moves ahead might be tricky for your opponent.

The engine dislikes the King Gambit, which has a pretty lengthy history, dating back to the 1600s [1]. However, it's not played much anymore at very top levels, and much has been written about its weaknesses [2]. So in some sense, humans have been "trying" the King's Gambit for centuries and have only recently come to the conclusion that it's not optimal.

Many players enjoy using the opening simply because it leads to dangerous and exciting games, so it makes sense that Stockfish and other engines would prefer conservative opening lines.

> I tested the new feature on my favorite opening: 1.e4 e5 2.f4!, a.k.a. the mighty King Gambit. Stockfish hates it, and asked me to review it like it was a mistake! Yet it's considered playable. Actually Carlsen played it against Arionian in 2015.

Not acceptable, Mr Stockfish!

Actually, the King's Gambit has been (essentially) solved: https://en.chessbase.com/post/rajlich-busting-the-king-s-gam...

There is only one move that doesn't lose by force after 2. ... exf4, and that is the strange-looking 3. Be2. Does that mean this opening is a "mistake"? Well, maybe not, obviously a human wouldn't know the perfect lines, but personally I wouldn't play it :)

Either way, I'll certainly be using this feature a lot. Kudos to the folks at Lichess.
