Getting to the bottom of it ( part 2 )

Last post discussed the Seidel-Hall attack in the Teichmann Exchange line, with black playing the "inferior" 10...Bd6.

We learned that, despite a marvellous sacrifice in one particular line, white could not achieve equality when playing 11.00

So let's look at the alternative 11.Ne4

a/ 11...00 12.Bd2 Black's bishop is badly placed, with white have great attacking chances in all lines,
a1/ 12...Bc7 13.h4 with a tiny white advantage, eg 13...Nbd7 14.000
a2/ 12...Na6 13.000 with a small white plus
a3/ 12...Be7 Yes my computer suggests this retreat ( is he desperate for good black moves ?? )  13.000 equal
a4/ 12...e5  13.c4 Ne7 14.h4 exd4 15.h5 with an obvious advantage for white despite the two pawn deficit

b/ 11...Bc7 12.Rf1 giving white the better play

b1/ 12...00 13.Qh5 and white is better
b2/ 12...Qe7 13.Bd2, equal aftre 13...Nb4 14.Bxb4 Qxb4+ 15.c3 Qe7 16.000
b3/ 12...Qd7 13.Bd2 and a small white advantage

c/ 11...Nb4 12.00 White unleashes a violent attack

c1/ 12...00 13.Nf6+ Where have we seen this before ? and black can safely resign
c2/ 12...Qe7 or 12...Qd7 13.Qxf7+ winning
c3/ 12...Rf8 black's only chance of survival 13.Rf2 Nxd3 14.Qxd3 with a small white advantage

d/ 11...Be7 loosing a tempo, but that's not so bad yet, as the e4 square is not available for the white queen 12.Bd2

d1/ 12...Nd7 13.000 with complete equality

d2/ 12...00 13.000 and white has a small initiative, eg 13...Nd7 14.c4

d3/ 12...Qb6 13.c4 and white is slightly better

d4/ 12...Qc7 13.000 and white is better

e/ 11...Na6  12.Rf1 with a small white advantage.

Bottomline, playing 10...Bd6 in the Seidel Hall variation of the Teichmann Exchange variation does not offer anything for black if white answers correctly 11.Ne4. White should avoid the incorrect 11.00 as black will have a slight edge.
