Milking the position

In dutch, "milking the position" means that the player manoeuvres very slowly and carefully as to exploit a very small positional advantage. Of course, that does apply to the vast majority of Blackmar Diemer positions, but still, you might need to do so as to show an advantage.

I learned that the Teichmann defense might give black a smalkl advantage after1.d4 d5 2.e4 dxe4 3.Nc4 Nf6 4.f3 exf3 5.Nxf3 Bg4 6.h3 Bh5 7.g4 Bg6 8.Ne5 e6 9.Qf3 c6 10.g5 Nh5.

So I decided to look into 9.Bg2 c6 10.h4 Bb4 and showed that white has equality.

But is there an advantage for teh attacker. My earlier analysis only considered 11.00. So let's look today at 11.Bg5 (diagram) and see if this one can bring white an advantage.

The move looks rather stupid, as it seems to block the advance of the g pawn.

The most natural black move in this position is clearly 11...Nbd7, attacking white's outpost. However white can now can a small advantage attacking the bishop 12.h5 (diagram)

 a/ 12...Nxe5 13.dxe5
...a1/ 13...Qxd1+ 14.Rxd1
......a1a/ 14...Be4 15.exf6 Bxg2 16.Rh2 (+=)
......a1b/ 14...Bxc2 15.exf6 (+=)
......a1c/ 14...Ne4 15.Bd2 (+=)

......a1d/ 14...Bxc3+ 15.bxc3 (+=)

...a2/ 13...Be4 14.Qxd8+ Rxd8 15.exf6 Bxg2 16.fxg7 Rg8 17.Rg1 (+=)

...a3/ 13...Bxc3+ 14.bxc3 (+=)

...a4/ 13...Qa5 14.exf6 Qxg5 15.hxg6 (+=)

b/ 12...Qa5 13.Bxf6

...b1/ 13...Bxc3+ 14.bxc3 Qxc3 15.Kf2 (+=)

...b2/ 13...gxf6 14.Nxd7 (+=)

c/ 12...Bxc3+ 13.bxc3 (transposing to other lines ) (+=)

d/ 12...Be4 13.Bxe4 Nxe5 14.Bxf6  (+=)

e/ 12...Qc7 13.Bxf6 (+=)

So we see that whote can get a small advanatge aftre the natural move 12...Nbd7. Unfortunately, black has some other moves, which we will analyse on a further post.
