6 ) Skewer Attack
7 ) Beautiful skewer attack, here King cant defend its Rook because of our Rook is controlling f file.
8 ) Skewers attack from Queen , King cant defend its Rook after attack, because of its friendly pawn.
Later on white also have counter attack- b5 pawn move which leads to fork attack from pawn.
9 ) Black's Rook Pins the King , So Black will do sacrifice from its Knight, if Rook or pawn captures then black loses material and loses game quickly because dXc4 immediately check on the King and loses materials. Black will have more pawns and easy to win game. So exchanging piece is not good always. first see the position of the game then decide exchanging piece better for your game?
So here better move for white is Rd1.
