  <p>What surprises me in particular about OP's question is that multiple lines option helps show how sharp/critical a position is. Eg I loaded a <a href="https://lichess.org/training/5Bypy" rel="nofollow noreferrer">puzzle</a> on lichess and here's what I have:</p>

The orange <a href="https://matheducators.stackexchange.com/questions/13700/in-what-curricula-are-rectangles-defined-so-as-to-exclude-squares">box</a> shows there are 2 drawish moves.

Answers.Body: <p>Yeah engines can do it. Here's how you do it on Lichess:</p>
  <p><a href="https://i.sstatic.net/q8pGH.png" rel="noreferrer"><img src="https://i.sstatic.net/q8pGH.png" alt="enter image description here" /></a></p>
  <p>Then when you run the analysis the engine gives three moves. You can increase the number of lines you want as well, which can be a waste since in this particular position, Black really only has one good move (...g6) so resources spent analyzing the 2nd-best (...Ke7) and 3rd-best (...Qf6) moves are wasted.</p>

Body: <p>Especially for checking studies (maybe also for teaching), it would be helpful to have an engine finding the second best move and assess it (or even give refutations of all alternatives). For a tablebase position, this is trivial. Can the Lichess/Stockfish engine do that? If not, do (especially online) alternatives exist?</p>
