A Personal milestone: conquering the Colle system.


A nice mate with the Knights, but technically, to be a "smothered" mate doesn't the king have to be confined by his own pieces not one of the opponents' as in the classic Philidor's legacy pattern?
Still any blow against the Colle warms my heart. (Although you did not beat it straight up, but employed a King's Indian setup, my favorite thing to do, avoiding the main line so prominently advocated by Koltanowsky.)

It's odd Black decided to continue in a Colle fashion after 2...g6. A favorite saying of Koltanowski was, "You do not have to be othodox about sticking completely to the Colle line if your opponent varies." Koltanowski actually answered ...g6 with c4!
7.a4? - Castling is much better. White needn't fear ...c4 nor ...dxc4.
8.h3? - White wastes more time on weakening pawn moves.
9.Bb1? - White is asleep at the wheel.
13.c4?? - Hanging a pawn.
Nice checkmate. :)

=) thanks for the comments, this is especially heart warming because I have lost in USCF tourneys to the Colle System, being prepared only for Queen Gambit lines.
