It aint that bad

In my quest to refute the refutation of the Teichmann defense, I studied the line 9.Bg2 c6 10.h4 in the Tecihmann defense 1.d4 d5 2.e4 dxe4 3.Nc3 Nf6 4.f3 exf3 5.Nxf3 Bg4 6.h3 Bh5 7.g4 Bg6 8.Ne5 e6.

It is obvious that only 10...Bb4 gives black a chance to survive. White now has both 11.00 and 11.Bg5 at his disposal.

11.00 was discussed in an earlier post as white risks all to trap an enemy piece. Analysis shows that white has nothing to fear in this line.

More enterprising is the line 11.Bg5 and I looked at the black replies 11...h6, 11...Qa5, 11...Nbd7 and 11...00

The black defense 11...h6 seemed to give white some headache, but 12.Nxg6 fxg6 13.Bxf6 Qxf6 14.Qd3 seemed to equalize.

Igor S from Russia then mailed me that black gets the better game after 14...Nbd7 15.000 000 (diagram)

I initially agreed with him, but aftre carefull analysis, it seems to me 16.Kb1 (diagram) gives white full equality :

a/ 16...Bxc3 17.Qxc3 (=)

b/ 16...Qf2 17.Be4 (=)

c/ 16...Qe7 17.Ne4 (=)

d/ 16...Nc5 17.Qc4 Bxc3 18.Qxc3 (=)

e/ 16...Nb6 17.Ne4 (=)

f/ 16...Kb8 17.Qg3+ (=)

So it seems my Russian friend was wrong and that the line 9.Bg2 c6 10.h4 in the Teichmann Defense is certainly not refuted in any way !
