Last post focused on black's immediate attempt to exchange in The Long Bogo by playing 8...Bg4.
Unfortunately for white, black can also try 8...Nd5, attcking both the knight on c3 and the bishop on f4. So this move is black's second try to exchange pieces.
White should complicate matters with 9.Be5
a/ 9...Bxe5 ( simplest but very bad ) 10.dxe5 c6 11.Qh6 ++
b/ 9...Nxc3 10.Qxc3
..b2/ 10...Bf5 11.h4 =
..b3/ 10...Nd7 11.Bxc7 Qe8 12.Bb5 =
..b4/ 10...Bh6+ 11.Kb1 =
c/ Bf5 10.Bxg7 Kxg7 11.Bc4 =
d/ Bg4 10.Bc4 =
e/ Be6 10.h4 =
f/ Nf6 10.Qf4 =
g/ c6 10.h4 =
h/ f6 10.Bg3 =
Bottomline, black's try to simplufy the Long Bogo 8...Nd5 does not bring any advantage for black nor white.
