{In opening positions of calm nature and no
direct enemy contact, you often have the choice of different move orders to achieve your desired setup. In many cases, the specific move order
doesn't make a difference, but sometimes an optimal move order definitively
exists, either providing you with more flexibility in the future or,
contrariwise, depriving your opponent of certain options. In this game my 9th
move was bad, because it failed to eliminate an aggressive option of my
opponent.} 1. e4 e5 2. Nf3 Nc6 3. Bc4 Bc5 4. c3 Nf6 5. d3 {Diagram [#] I
received a second chance to play the "little Spanish". This time, my opponent
developed his bishop more actively. Indeed, this boy was a genuine attacking
player, as you can see by the course of the game.} d6 6. Nbd2 a6 7. Bb3 O-O 8.

structure, preparing Nd2-f1-g3, a look into ChessBase's online database easily
reveals, that it was a mistake in this specific position. Not only did the
correct move 9.h3 occur much more often, also the results after 9.Re1 ranged
clearly under 50%. Today, I would play 9.h3 and if 9..Be6, I would conserve
my piece potential with 10.Bc2. This is how the top protagonists play for an
advantage here.} Be6 $2 {The way to punish White for his inaccuracy is} (9...

awkward for Black. White doesn't have to necessarily capture the very next move,

the dangerous Ba7. But here, it simply doesn't work.} (13... Ng6 14. d4 $14 {
A note for readers, who are not familiar with this type of position: The fact,
that White started out rather passively with the pawn on d3, doesn't mean that
this structure has to stay like that forever. After White has completed his
development, he is ready to strike with d3-d4 at the first convenient moment.})
