LiChess 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…

I saw someone else above mention an iOS app, and it looks like there also is an Android app.

It was an April Fools Prank. Apparently a good one.

Most of the times I get this message when I open lichess. Your connection is not private Attackers might be trying to steal your information from en.lichess.org (for example, passwords, messages or credit cards). NET::ERR_CERT_AUTHORITY_INVALID This resolves after 2-3 days and then within a week it again reappears.

check with your ISP/vpn, works fine for me

Hi Tom, yes, but mobile apps don't make a website work offline on windows, linux or osx unless you are proposing the Android app can be run through Chrome APK welder (if it works). But even if that were the case, I think the current Android/iOS apps don't allow you to asynchronously play chess, but only offline against the AI. Scenario's would be having a spotty or on/off connection for example, or playing one turn/hour or day. Progressive web apps can work offline and sync the state back to the cloud when online.

Gotta ask and I ain't trying to start a flame war here.... how's the community compared to say, ICC? I was a big time user of ICC back in the day simply because the average player was high caliber after FICS started to become a bit of a dead zone for standard players (I like 45 5 or higher timed classic games )

There are more high level players on ICC because that's where the high level players are. Chess.com also has a decent interface, but they particularly excel in chess news, event coverage and community support.

ICC is basically dead, even top players are leaving. Takes forever to get a game.

> If at least two masters have played a move in tournament situation, then the move must be playable! So that's how it works now. Considering how much Stockfish is stronger than those masters, those moves could be really wrong despite being playable in human vs human games. http://www.computerchess.org.uk/ccrl/404/cgi/compare_engines... Hoowever we don't know the estimated ELO of Stockfish as used by Lichess.

No, there are positions where computers are known to make the wrong decisions. Computers use opening books instead of evaluating the moves themselves because they don't evaluate openings well.

After some exploring I came across a "good enough feature": correspondence chess. On the website and the mobile apps you can login en logout a game (including the variants) in between turns and set the window from 1-14 days per turn! The only thing is that you don't get notified when a person has taken their turn, except when you are on iOS i read. Well, you can always exchange chess notation through Riot, e-mail or snail-mail :-)

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.

If your goal is to win, wouldn't you want to play the move that always leads to a win 10 moves ahead, rather than a move that looks immediately tricky but is actually escapable for the other player? And given that you want to become a better chess player, isn't it better to start learning the best lines from the start?

If your goal is to win, you should play moves that lead to situations where you will do significantly better than your opponents, given what you know of their strengths and weaknesses. Whether they are good or bad from an 'optimal play' perspective doesn't matter.

For example, if chess is a win for white, you play black, and you have a halfway decent opponent, he will know what black's best defense looks like (that is: the one that takes him the most moves to win). Replaying that gives you zero chance of winning or drawing. Deviating from the beaten path cannot decrease that chance, and may increase it.

It is similar when chess, played optimally by both players, turns out to be a draw, and you want to win, but in that case, you may not want to give up your assurance of a draw, so you may play less weird moves. You still will want to play moves that lead to plays your opponent is weak at, though.

> If your goal is to win, wouldn't you want to play the move that always leads to a win 10 moves ahead Sure, but the King's Gambit is just an opening, and you'd have to rely on lazy mistakes to guarantee a win 10 moves ahead that early in the game.

Right, but game theory tells us that for every single position, perfect play either leads to a win for one player or a draw, and for every position, there is a best reply. To the extent that an AI approaches perfect play more closely than a novice or masters from the 19th century, shouldn't we go learn from the AI? One interpretation of Stockfish here is 'I don't think this is a very strong opening'. To the extent th…

Chess engines (I suppose that could be called AI) as well as databases of games have developed opening chess theory very significantly because of these reasons.

For perspective, Bobby Fischer created a version of chess which randomized the game because even in his day, he was annoyed that some players that he felt were far inferior at playing chess, could actually better memorize opening lines and enter the mid game with an advantage.

So the answer is that players very well have been learning from AI.

>To the extent that an AI approaches perfect play more closely than a novice or masters from the 19th century

AI has become better than even the top chess players of today.
