1. Click the board you think Stockfish would evaluate as a better position.
2. Make your judgement from whose turn it is. For example, if it's black to play, is it a good position for black?
3. If you think Stockfish would evaluate both positions within 0.1 points of each other, you can choose the equal sign instead of a board. (also applies to checkmates)
Be careful though, it's only equal if the two sides that are playing are winning/losing. If one board is getting checkmated and the other board can play checkmate (from your orientation's perspective), the board who can checkmate is always winning.
Note: Evaluations may be slightly off at lower depths from what Stockfish would evaluate
at higher depths and therefore some lines may not be the absolute optimal moves (this might make the given evaluation very wrong).
I've included the depth for each evaluation and links out to Chess.com/Lichess with the board's position
if you wish to explore the position further using live engines or doubt the evaluation given.
