D05: Colle System with ...e6
This is not a fireworks game but a good example of a good knight v a bad bishop 1.d4 d5 2.Nf3 Nf6 3.e3 e6 4.Bd3 c5 5.c3 Nc6 6.Nbd2 Qc7 7.0-0 Bd6 8.dxc5 Bxc5 9.e4 0-0 10.Qe2 dxe4 [10...Be7 11.Re1 b6 12.e5 Nd7 13.Nb3 Nc5 14.Nxc5 bxc5 15.Bf4 c4 16.Bc2 Rb8 17.Rab1 Bd7 18.Ng5 Bxg5 19.Qh5 h6 20.Bxg5 Nxe5 21.Bxh6 Ng6 22.Bxg6 fxg6 23.Qxg6 Rf7 24.Re3 e5 25.Rf3 Rbf8 26.Rxf7 Rxf7 27.Re1 Qc6 28.Qxc6 Bxc6 29.Bc1 e4 ½-½ Miolo,E-Jussupow,A/Indonesia 1983/MCD (29)] 11.Nxe4 Nxe4 12.Bxe4 f5N
this is probably the strategic error because, when the dark-squared bishops come off, e5 then belongs, absolutely, to white

13.Bxc6 Qxc6 14.Be3 b6 Secures c5
15.Bxc5 bxc5 white also benefits from a better pawn structure now that Black's Queen-side pawns are isolated
16.Ne5 The knight likes it on e5
16...Qa4 17.c4 Bb7 18.b3 Qe8 19.Rad1 Rd8 20.Rfe1 Qe7 21.Rxd8 Qxd8 [21...Rxd8 22.Rd1²]

22...Qg5² Threatening mate... how?
23.f3 Covers e4
23...Rd8 24.Rxd8+ Qxd8 25.Qd3 Threatening mate: Qxd8
25...Qc7 26.Qd7 Do you see the mate threat?
26...Qc8? [26...Qxd7 27.Nxd7 Bc6 28.Ne5+-]
27.Qxc8+ [¹27.Qf7+!? and White can already relax 27...Kh8 28.Qe7+-]
27...Bxc8 28.Kf2 Kf8 29.Nd3 Ke7 30.Nxc5 The passed pawn on c4 quickly leads to threats
