Explaining red card criteria

I'm breaking down the criteria for a red card: if there's a denial of an obvious goal-scoring opportunity (DOGSO) without trying to play the ball, it's a red card; if a player attempts to play the ball inside the area, it’s a yellow but still red outside. For goalkeepers, handling DOGSO outside the area leads to a red card. Early red cards notably affect expected goals, lowering them by about 0.6-0.8 goals. I can provide a structured summary or a flowchart if needed!
