Hi,

1.e4 e5 2.Nf3 Nf6 3.Nxe5 d6 4.Nf3 Nxe4 5.d4 d5 6.Nb1-d2

Hiarcs and Fritz Deep Analysis sees this 6th move as best for white,
where all the theory books say 6. Bd3... I can't figure this out...

thanks,
joey

I mean when I play Hiarcs, a computer program, it makes this move half
the time... Plus, I am working with Bookup, trying to outline the
openings I will use with the reasons for each move, so I want to put a
response in there to this out of book white move.

I don't play online or correspondence yet. I only play the computer or
a real human being in person with a real board and pieces, and a couple
pints of Guinness.

thanks,
joey

So I've got a stupid followup question. Were you asking here for advice
on how to play in an ongoing game? If it's against a computer, that's
ok, but if you're asking other people for suggestions for moves in a
correspondence game, that's generally considered pretty rude, if not
outright cheating.

thanks Richard,

I'll just keep playing this position and see how the games turn out.

Just because the move isn't the best possible move, it doesn't mean
that it's a bad move. "Book" lines are the lines that grandmasters see
as the theoretical best, but it doesn't move that any time someone
varies from them, there's an immediate refutation. Just play the best
moves you can, and if their moves are truly inferior, it'll show in the
resulting position. But there are plenty of non-book moves, in just
about every opening, that are perfectly playable.

thanks,

So then should my response be something that makes it clear the knight
should have gone elsewhere ... and make white waste a tempo??

Computers generally don't see far enough to judge openings (unless
there are immediate tactics.) In this case, it's not clear yet where
White should place the Queen's Knight, d2, c3, (a3?). White really
hasn't any better spot for the King's Bishop; thus 6.Bd3 places the
Bishop where it should be and defers a decision on the Knight.

Likewise 6.Bd3 allows White to Castle quickly; this is often importan
in this variation of the Petroff. The Rook may also be useful at e1 to
increase pressure on Black's Knight.
