Lichess puzzles

i have seen that in some puzzles , only the best move is considered the acceptable move and in some others they are few good moves ( in those puzzles lichess says it's a good move but you can do better ) . I don't know whether this is also true about the " not the best checkmate sequence " or not ( i think in some games it is and in some it's not !! )
so i think there should be a more intelligent engine to analyse these moves and don't say simply " puzzle failed " :D
for example this :

lichess solved it in easier and i did it in another way . i think that was better to say that " it's a good move but you can do better " .

Also , i think every player can help lichess in creating more interesting puzzles by posting the position of his games ( or even other games between different players ) .
actually i think this is the best way to collect the best puzzles for lichess and improve their quality .

Thanks :)

Many (maybe all?) of the puzzles are from games; although the sequence played in the game and the puzzle answer usually differ. There is an icon to click and see what game it is from.

I agree it can be annoying to not get credit for what is a winning solution. However, in improving our chess it is probably best to look for the best continuation. I know I have a lazy mind and many times will settle on simplifying a winning position instead of looking for the best move (really only okay for bullet). In short, I like the puzzle scoring system because it forces me to look deeper into positions.

I am not interested to see posted game puzzles that could have come from other sites or that someone else played OTB. I would prefer the option to selection moves from a game we played on Lichess after requesting a computer analysis of our game.

What is missing after an analysis is a radio button to be able to select example: Error or Blunder #3 selected for training puzzles.

Most puzzles are quite OK, but occasionally I doubt that their "programmed" solutions are right; for example, #56092

Anybody else feeling the same, or am I just not strong enough to understand them?

#56092 is correct. White has to prevent mate on every move.

Sure, thanks. But what if instead of
black f5d3
white c1c2
black b2c2

.. white would choose:
black f5d3
white c8c4

You are most probably right, but I'm too tired right now to see how that would end. It would be nice if there was a mode in puzzles where the player could arbitrarily continue to test own ideas.

In your line it would be 1.... Qd3 2. Qc4 Qd2+ 3. Kf1 Qxf2#.

You can reach the analysis board after you've solved or failed the puzzle if you click on the microscope button, btw. I don't think this option should be available beforehand, it would just encourage sloppy thinking.

Thanks a lot, now I see it!
