Make full use of the Queen sacrifice

Chess Checks

Sometimes the queen is sacrificed for two rooks or three minor pieces, depending on the position. The follow up after the queen sacrifice has to be precise as even the slightest weak move can result in a loss.

However it is not always that the queen sacrifice works in a game of chess and the game which follows is a good example of that. Black sacrifices his queen in a equal looking position and thereafter is not able to maintain the rhythm.

White: Judit Polgar (2550) – Black: Gyula Sax (2600)
