Bishop and Knight Mate Practice Bug? • page 1/1 • Game Analysis • lichess.org

https://lichess.org/pNdo0fhD/white#3

I was practicing with Stockfish 8 on a bishop and knight checkmate, but yet for some reason on some moves it shows that I am gaining a non-checkmate advantage(like +2, +3), even though there could potentially be a checkmate, and if it’s NOT a checkmate, it would usually be a draw due to the 50 moves rule

Is there a reason why its this way?

(I put this on game analysis to ask whether the eval bar is correct and it is indeed a draw or if its just a bug)

From what I understand , engines have to get to a certain depth to see that its some kind of a forced checkmate possibility.
Also If you made a move that is suboptimal the engine has to recalculate and often declares that you've thrown away your advantage until it can again get to a certain depth to see the checkmating advantage.
Also I think the engine just goes by those endgame "tables" like DZT50 or whatever (a lot of those endgame positions are solved already and I think the engine just plays whatever optimal database move)
