When White moves this pawn forward...
He is attacking Black’s central pawn
Black puts his pawn here (to defend the pawn)
White puts this Knight here (to attack the pawn)
Black replies by moving this Knight (to defend)
White then moves the Queen
To attack this pawn
Black defends it by moving the Queen here
White moves this pawn (to encourage Queen trade)
Black takes the Queen
White takes the Queen
Here White has Queenside advantage
This dark-squared Bishop is bad for Black
So White can move this pawn forward
To open up Black’s pawn structure on Queenside
After an exchange, this c6 pawn becomes weak...
And Then Attack on Black’s Queenside
