This is what I got from "ChessCademy -> Attack and Defence -> Attacking Castled King -> Combining Focal points" lesson. After this small play, I got :
Excellent! After attacking the g7 square, black is forced to close off g8 as an escape square for his king. From there, you opened up the h-file, resulting in a decisive attack.
I don't understand how White got an advantage and there why Black did the moves he did. Sadly, I didn't find a way to get the more in depth analysis on the website, or have variations of games that I could play. It would be wonderful if someone could explain to me, or show, why White is winning and was this the best course of action? Is there anything else Black could have done to better himself?
