Breaking through the enemy walls

Chess Checks

Castling in a game of chess is a manoeuvre done with the intention of safeguarding the King as the pawns and pieces act as a castle wall for the King. The game becomes interesting if the opponent can breach the castle early with a piece sacrifice and catch the King in a checkmating net.

The game which follows is a thrilling one where White sacrifices a knight early in the game to shatter Black’s castle. Thereafter White’s pieces start closing in around the Black King and he is forced out of his shelter. To add to Black’s woes, his rook and bishop on the queen-side do not get an opportunity to enter the game till everything is lost!
