By making a Queen sacrifice the four-time Italian Chess Championship winner Alberto Giustolisi emphasizes the weakness of the long diagonal and the h-file! Checkmate follows immediately once White accepts the sacrifice! A brilliant Rook and Bishop cooperation! In the end of the video as usual you can solve the daily puzzle!
