Chess Checks

Here the players have to carefully do their home work (opening study) as the minutest of advantage gained here, can determine the eventual outcome of the game. The advantage could be in terms of good pawn structure or placement of pieces as these days it is very rare to get material advantage in the openings.

In the game which follows, a strong opening by White results in him getting a bishop pair while Black has to exchange off one of his strong bishops. The advantage of the bishop  pair is nicely emphasized in the way in which White wraps up the game.

 White: Viktor Bologan (2620) – Black: Dmitrij Bunzmann (2596)
