Key Move Against the Dutch
Here is a game from the 2008-2009 Bundesliga, GM Golod - FM Deglmann with full commentary and annotations:
In this game we see the move 6. b4!? which is a very aggressive and interesting choice to combat the Dutch defense. White looks to immediately gain space on the queenside while black was playing on the kingside. And in this case black pushed the panic button and lashed out in the center prematurely which led to white forcing a weakness on d6. Then white was able to take control and use the d5 hole created by the weakening in black's position. With the dominant Knight on d5 white just had too many threats and the pieces came flooding into the black position when victory was swift!
