In the Rubinstein System...
White moves this pawn forward
Black castles Kingside
To protect his King
White replies by moving his Bishop here
Black moves his Queen’s pawn
White moves this King’s Knight here
Black replies by moving this pawn
White castles Kingside
To protect his King
Black takes d4
White takes d4-pawn
Black takes c4
White takes Black’s pawn
And he gains an isolated pawn...
Black moves this pawn
White replies by moving his dark-squared Bishop here
He pins the Knight to the Queen
Black fianchettoes his light-squared Bishop
To control this diagonal
White can develop his pieces like this
To put some pressure on these files
Black’s idea is to blockade the d4 pawn by putting a Knight
And not to let White liberate himself with the d4-d5 break
He also can develop his pieces like this
Or take the Knight
To increase the control over d5
