What a difference those additionals bits make

I upgraded my laptop some time ago from Windows 7 32 bit to 64 bit and moved to the 64 bit version of Houdini. What a difference these additional bits make ! It seems that my analysis runs a lot faster and deeper now. I am looking forward to the 128 bit version of the operating system - imagine what a difference that will make in chess analysis ?

In my book "Attack with the Blackmar Diemer, I covered a line in the Teichmann incorrectly. After 1.d4 d5 2.e4 dxe4 3.Nc3 Nf6 4.f3 exf3 5.Nxf3 Bg4 6.h3 Bh5 7.g4 Bg6 8.Ne5 Nfd7, I suggested 9.Bg2 which leads to nothing after 9...Nxe5 10.Bxb7 N8c6 11.dxe5 Qxd1+ 12.Nxd1 Be4

But I now find that 9.Nxg6 hxg6 10.Bg5 (diagram) is far better.

a/ 10...f6 11.Qd3 (+)

b/ 10...c6 11.Qe2 (+=)

c/ 10...c5 11.d5 (+=)

d/ 10...Nc6 11.Bg2 (+=)

e/ 10...Nf6 11.Qf3 (+=)

f/ 10...Nb6 11.Qd3 (+=)

In the related line 8...Nbd7 (diagram), I suggested 9.Qf3. But now I see that 9.Nxg6 is also possible, often transposing. But since 9.Qf3 yields a more complicated play, I will keep this as the recommended move.

g/ 9...c6 10.Nxg6 hxg6 11.g5
...g1/ 11...Nh5 12.Bc4
......g1a/ 12...e6 13.Rf1 Qe7 14.Bd2 (=)
......g1b/ 12...f5 13.gxf6 exf6 14.Bd2 (=)
......g1c/ 12...f6 13.Qe4 (+=)
...g2/ 11...Nh7 12.h4 (+=) (Improving on 12.Bc4 I suggested earlier)
...g3/ 11...Nd5 12.Nxd5 cxd5 13.Qxd5 (+=)
...g4/ 11...Ng8 12.Bc4
......g4a/ 12...e6 13.Rf1 (+=) (Improving on 13.00)
......g4b/ 12...f5 13.Be6 (++) (Improving greatly on 13.Be3)

h/ 9...e6 10.Qxb7 ( or 10.Nxg6 )
Will be covered in a following post

i/ 9...Nxe5 10.dxe5 Nd7 11.e6 fxe6 12.Qxb7 (+=)

j/ 9...c5 10.Be3 (+)

k/ 9...Rb8 10.h4 (+)

So my 32 additional bits really make the difference, as more and more small white advantages appear on the board !
