Josif Dorfman:
2B + N vs 2N + B
Concept
Usually, chess games are played in
accordance with the well known strategical
rules. But sometimes, in modern practice, we
have solve a problem in very contradictory
situations. I described already in my books
and in some articles a new theory when we
don’t speak about two bishops, but about
two B+N against 2N+B. We shall learn, how
to proceed in such cases. In the first game I
was a proponent of my own strategy.

Here, nothing betokened a conflict.
According to the pawn structure White has
break the center with e3–e4. But according
to the material, White needs the Knight to
develop his play on the light coloured
squares.

The ability to identify critical points in the
game is extremely important.Black prepared
the transfer of his Bishop on d6. White takes
an appropriate action.

We can realize the depth of Bronstein's
undestanding of chess after 8...Ne4 9.Ne4
Now, according to my rules, White, who has
two N and a B against two black's B and N,
is playing for exchange of darkcoloured B
and the N. The goal is to get a favourable
couple Q+N against Black's Q+B. After this
symplifications a very important resource
c4–c5 will appear.

Or 8...0–0 9.0–0 c5 10.Bg5 10.Bc2! and
White contols the outpost e5 and therefore
has avoid the useless exchanges.
9.Bc2 0–0 10.0–0 c5 11.Ne2
In such cases it's important to activate the
queenside majority by a3, dxc5 and b4.

Obviously, such occasions are rare in all
professional careers. However, when it
happens, like in a very recent game In
EECC, Skopje 2015, it’s a real aesthetics.

Here we have a very modern position with
the same conflict. White needs be able to
break the center avoiding the exchange of
Knights.
8.Bd3 Nbd7 9.0–0 Bd6 10.h3 Qe7
Black has many options here, like 10...Bc7,
10...a6; 10…0-0 or 10…dc4.

Strange, but it's a novelty! Other possibilities
are 11.cd5, 11.Bd2, 11.Qb3 or 11.c5.
