When black plays g6, white's attacking plans become very obvious. h4 is a natural undermining idea which aims to punish g6 - a weakness which is exploitable in practice. In conjunction with Ne5 jumps, this means that white will most often play a kingside attack if black chooses to go for this setup.
There are three ways to play against g6, I have covered them all. Below you can find timestamps for each chapter.
