My stockfish (analyze tool) has disappeared. How can I get it back?
You might have accidentally hit the 'Z' key, which toggles the analysis tool. Tapping 'Z' again should make Stockfish show up again.
or you somehow disabled computer analysis
click on the options (those 3 lines) button on the right hand side of the board and enable comuter analysis again
Thank you, WightUnderscore, to tap z functioned. Thank you, Leasy, too.
