#82I'm a big fan of lichess. Great UX and analysis features. The only issue I have with it is that disconnection auto-forfeits the game. Would love 30 seconds grace to reconnect (like they give you on chess.com).

For tactics I've never seen anything better than chess tempo [0], which is free, or for a small yearly subscription you can absolutely go nuts breaking down tactical themes and combinations of themes, and the tracking is very good. I did several thousand tactics puzzles there and it helped quite a bit.
For books, Beginners Mind by Jeremy Silman is pretty good, as is his endgame book. Logical Chess by Cherenev is also a great introduction to how skilled people think about games but takes a different approach than Silman.

I learned a lot from the tutorials by Joshua Waitzkin in Chessmaster: Grandmaster Edition. I heard that lichess has some puzzles as-well, but never tried them.

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.
Sorry, but this makes my head hurt. >>> 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? > Sub optimal from the perspective of the AI There's no perspective involved: optimal play is perfect play, assuming the opponent also plays perfectly. If a move is sub-optimal for White that means White has a better move,…
Of course there's perspective involved.
Restricting yourself to perfect opponents is very silly firstly, because there are no perfect opponents because chess is unsolved. So right out of the gate our definition assumes the counterfactual for all chess games every played and is both inaccurate (does not describe actual chess) and impractical (cannot be implemented)
Secondly, if there were such an opponent (which is not at all clear there ever will be), there is no way within the rules of chess to detect whether or not we face it in a given game. Imperfect opponents are allowed to play chess, and assuming they are all perfect while a defensible strategy is merely one of several.
Thirdly, it leads to very counterintuitive results. Consider the case in which chess is solved and well-balanced (e.g. a perfect opponent P can force a draw). We modify P to create opponent NP. NP behaves as follows: if NP's opponent is consistent with P, NP will implement P (e.g. force a draw), if NP's opponent deviates from P, NP will lose (forefeit or make bad moves). Therefore everyone can beat NP except "optimal" algorithm P, which can only force a draw. So now we have an "optimal" algorithm with a 0 tournament rating.
In reality the whole "perfect opponent" thing is mostly a notational convenience for Zermelo's Theorem. Which is very interesting and useful if you are writing a proof, less interesting if you are trying to win a chess tournament. A more practical definition of "optimal" is something like "wins a lot of games".

Thibault simply wants to deliver the best online chess experience. Period. It's purely donation driven and he pulls a small salary from whatever's leftover after buying enough servers to keep the site up.

I'm supprised that they get $47 mn in donations. Rarely see the patron icon when I play.
Re: LiChess: Learn from your mistakes
#88LiChess is one of the most amazing hosted platforms out there, it's very fast, it has a minimalistic design, it has no ads and does the thing that it does very well. Furthermore they sympathetically state: "Lichess mobile is developed and translated to 80 languages by volunteers. Just like the website, it's 100% free forever, and there will never be advertisements. This is humanist software, made open source for the…
>new variant to change the chess rules to accommodate a smaller board 5x6, 4x5 or 6x6 for even shorter games.
That makes no sense. You can have games as short as you want. Just play using a different time control. I play 1+2 (minute plus seconds) and those games last 2 to 3 minutes at most.
BTW with variants, you're not really playing chess anymore. You're playing a different game with chess pieces. Not all the strategy and tactics transfer well if at all.

#89Lichess is so awesome, it really changed my life. The features I use most:
1. The tactics trainer is incredible and fun. You get tactics ELO and the tactics stem from real games. Hence you can replay the game and see how this position arose.
2. The new tactics trainer from your own games is wonderful (but many other desktop programs had this before).
3. The analyse game function using stockfish is wonderful. Even continuously with a few lines + arrows in the game, you get immediately what you have missed.
4. The study section is awesome. I tried to build up a complete new opening repertoire with it in parallel to the leading chessbase tool. And guess what: It's free and a nice competitor to chessbase. All study pgns can surely be exported and imported to chessbase.
5. I really like the simul section. You find many dozen simuls a day. 25-50% of players are with 2000-2500 Elo.
6. And if you watch the lobby in the diagram mode you always find your right partner, right time, right chess variant.
7. And of course, the mobile version is also great.
Keep on guys! We love you.
