The Colle System and Kingside Attacks

A viewer asked me to create  a video on the dangers of castling, specifically, when is castling early a mistake.  Since this usually means castling into an attack, I focused on typical Kingside ideas.  You can see it below.

That said, the first part of the video deals with a Colle System game that completely shows everything involving a Kingside attack against the castled King.  See the full analysis of said game below, which expands on the video.

Mistakes.’} 1. e4 e5 2. Bc4 Nf6 3. d3 Nc6 4. Ne2 d5 5. exd5 Nxd5 6. Nbc3 Bb4 7.
O-O Bxc3 8. Nxc3 Nxc3 9. bxc3 {Notice how Black has traded his active pieces,
slightly worsening his position.} O-O 10. Qh5 Qd6 11. f4 Na5 $4 {Black’s
blunder allows a tactical finish.} (11… Be6 $1 {This is the best move. Black
likely avoided it because of the ugly pawns he gets after an exchange.} 12.
Bxe6 fxe6 {Yes, Black’s pawns are ugly, being doubled and on an open file.
However, he has completely stopped White’s attack. There are no threats, and
Black can use the f-file just as well as White. Black also threatens Qc5+,
forking the pawn on c3. That likely forces.} (12… Qxe6 13. f5 Qd6 (13… Qf6
$2 {Just brings the Bishop into the attack with tempo.} 14. Bg5) 14. f6 {
White’s attack practically plays itself. Black can only to defend with} Rfe8 {
[%cal Gd6f8] allowing Qf8 to cover g7.}) 13. Be3 Qa3 {And here we see the
second point: White also has weak pawns. Both the c3-pawn and also the a2-pawn
require protection. If White’s Rook is tied to the a-pawn, then White cannot
bring it into any potential attack. It also means Black can ‘threaten’ to
exchange on the f-file, distracting the Rook from the a2-pawn.} 14. c4 Rf5 15.
Qf3 Raf8 {Black is fully equal here. His weaknesses are no more significant
than White’s, and his forces are more coordinated at the moment. Just as Black
was too eager to inflict doubled pawns at the beginning, he was too quick to
reject this variation when he saw his own doubled pawns.}) (11… Be6 12. a4 {
Indeed, the computer suggests that this may be a better chance for White. The
idea is to bring the Bishop to a3 with a skewer.} Bxc4 (12… Qc5+ $1 13. Kh1
Qa5 {This is the computer’s main line, claiming full equality, though White
has practical chances with f5 if he wants to enter complications.}) 13. Ba3 Qd5
14. Bxf8 Rxf8 15. dxc4 Qxc4 {White is up an exchange but has six-thousand weak
pawns. Rooks can dominate Knights in an endgame, on an open board, so Black
will need to be on guard in the ensuing endgame. White has a comfortable, safe
advantage.}) 12. Bxf7+ Rxf7 (12… Kh8 {Someone asked an important question:
what happens if Black ignores the sacrifice? We should always consider this
possibility. Here, though, things are pretty easy. For one thing, White is up
a pawn, so at the very least he can just retreat and keep some extra material.
More importantly, he keeps his attack rolling.} 13. f5 {[%cal Gf7g6,Gh5h7,
Gg6h7] The threat is Bg3 and mate on h7, and Black has to give up copious
amounts of material to stop it.} Rxf7 (13… Nc6 {If Black ignores the threat..

Qe8+ with a back rank mate.} Bd7 15. f6 {Now Qxg7# is threatened, too.} gxf6 (
15… Rg8 {Protecting with the Rook doesn’t help either.} 16. Bg5 {Bringing
another piece into the attack.} Be6 17. fxg7+ Rxg7 18. Qe8+ Bg8 (18… Rg8 19.
Bf6#) 19. Bf6) 16. Bh6 Rg8 17. Rxf6 {White has a vicious attack in addition to
his extra material. Rejecting the sacrifice has turned out even worse for
Black than accepting it!}) 13. Qxf7+ Kxf7 14. fxe5+ Qf6 15. exf6 gxf6 16. Bg5
