1.d4 Nf6 2.Bg5 d5 3.Nd2 c5 4.dxc5 e6 5.e4 h6!? Pushes the bishop away from the queenside.

[The trade 6.Bxf6 Qxf6 gives Black a bishop pair.]

6...dxe4 7.Qe2!?
[7.Nxe4 Qa5+! 8.Nd2 Nbd7= is no problem for Black.]

It seems Black just has prevented the long castle.

White thought for 25 minutes before going to La La Land. While he is joking on the queenside, his pieces on the other wing are in deep freeze.

Of course!

9.Qb5+? Nbd7
The computers are screaming that Black is already winning.

Falling deaper into the abbys, but other moves are not helping either: [10.Bxf6 Qa1+ 11.Nb1 a6 12.Qc4 gxf6 13.Qxe4 Nxc5 14.Qd4 Bd7-+ ; 10.Nb3 a6 11.Qc4 Nxc5-+ ]

10...bxc6 11.Qxc6 Bb7!
The sacrifice gives the attack a nice rhythm. [The pace would be slower after 11...Rb8 12.Nb3 Nd5 13.Bb5 (13.Rxd5 exd5 14.Ne2 Bb7-+ ) 13...Ba3! 14.bxa3 0-0-+ ]

12.Qxb7 Qa1+ 13.Nb1 Rb8 14.Qxb8+
There is not much else White can do. [14.Qc6 Qxb2+ 15.Kd2 Bb4+ 16.Ke2 0-0 17.Rxd7 Nxd7 18.Qxd7 Qxc2+ 19.Nd2 g5-+ ]

14...Nxb8 15.Bb5+ Nfd7 16.Ne2 Be7 17.Bxe7 Kxe7 18.Nd4 Nc5!
Game over. The rest is silence. [Trapping the queen, for example 18...Ne5 19.Nb3 Qa2 20.Nc3+- was White's last trick.]

19.h4 Rd8 20.Rh3
Threatening 21.Ra3, but White's hopes are crashed immediately.

20...Nd3+! 21.Bxd3 Rxd4 22.Be2 Rxd1+ 23.Bxd1 Qa5 24.Nd2 f5 25.Rg3 Qe5 26.Ra3 Nc6 27.g3 Qd4 28.Re3 Nb4 0-1
