How can I play Colle System against Kingside Fianchetto? I enjoy the Colle System as white, because it often leads to a strong kingside attack for white without exposing my own King to significant danger.

However, when my opponent castles behind a fianchetto on the kingside, I often struggle to understand how to attack it, as it significantly blunts the attack of my Bishop at d3, and advancing kingside pawns would likely open my own King up dangerously.

Can anyone point me to a good example of how to attack a fianchettoed king from the Colle system?
If it conforms to your style of play, one possibility is to switch to a stonewall setup, which generally leads to a king-side pawn storm where the g6 pawn acts as a very convenient lever for opening up your opponent's king. It must be said, though, that an early king-side fianchetto followed by ...c5 to undermine the white center is probably one of the best and most aggressive ways to meet the Colle system, so if you're not prepared to vary your approach, you shouldn't be surprised if black achieves easy equality immediately out of the opening.
