Step 8 of the Game Analysis section of the ChessUp 2 Knowledge Base mentions the Key Moments button, but it doesn’t mention what the Exclamation Point button does. If I tap it, a series of moves seems to play out. What are these please, and how do I use them? After that, the button seems to pulse, until I tap it again and it stops. Sorry for being dim, but what’s all that about, please?
Key moments are moves where the eval/score of the game changed significantly. So typically this is a mistake by one of the players, and then whether or not the opponent took advantage.
So we are skipping ahead into the game to the point you need to review what went right/wrong. Decisive moments.
