interesting novelty completely changes the character of the play with respect

how my former trainer, the late GM Theodor Ghitescu, used to define chess

combinations of these moves on the lower boards of our national team
championship which made him issue this definition, but it may also have been
some sort of well masked display of envy with respect to Florin Gheorghiu and
Mihai Suba, our by far strongest players in the '70s and the '80s. Gheorghiu

achieved with either g2-g4 followed by Kg2 or Kfe-e2, Re1, Kf1-g1. Both plans

dangers for His Majesty. An additional plan would be fighting against the
c5-bishop with a2-a3 and b2-b4, but this would not do much for his kingside
development. Black has comfortable development, but still needs to decide
between castling right away or spending some time with ...Kf8-g7 in order to
avoid problems along the h-file. His structure is flexible enough, but he

128] Nikita Vitiugov supports the aggressive mood of his opponent! Computer
chess programs are skeptical about this decision. I think, Nikita made this
move without preliminary preparation for the game. He was surprised with the
early unusual decision of his opponent and spent a lot of time in the opening..
. But I think, now Nikita could surprise Maxim. It is a very rare event in
modern chess, when the game turns into a battle between people, not computer
analysis. This game was played in the last round of the prestigious tournament
with a big prize fund. We can admire the courage of both players! Bravo!
