Opening surveys in ChessBase Magazine 130

Exchange variations of nearly all openings are
quite unpopular with the second players, since White often gets to play for the
advantage without any risk. Naturally, in these lines there is a very
high demand to obtain an active game with Black. GM Dejan Bojkov shows how this is possible against the King’s Indian with 6.h3 and
7.dxe5, which he proved in practice at the Bulgarian Championship when he used
this variation to rake in the full point and clinch the title. Here you can see
the article (one of a total of 12 opening contributions) in full length.
