Q: How do I read the post-game computer analysis?

A: The red/green colored bars under each move represent the player's advantage at that stage in the game. Green means the player is winning, red = losing. The length of the bar represents by how much, i.e. how great or little the advantage is. Highlighted moves have been found by the chess engine to be notably less than optimal (a mistake or even a blunder). If you click on the highlighted move, you can see what would have been the optimal (best) move in that situation, as suggested by the chess engine.
