\/A rare move. [5.d4

5...Ng5
This is also a rare move. The opening looks like a clever choice by Jeroen, since engines seem to have problems to understand what is going on. [5...Nd6

White suddenly starts to go for black's king. At the moment it looks like white has not enough pieces on the kingside for a successful attack, but we will see.

Look how badly the queen is placed. White can bring all the pieces to the attack with tempo! [15...h6

23.g3!
Now the white king is safe. Black is a rook + pawn + bishop pair up, but in chess the king is more important than any other piece!

24.Bc3
Every piece is attacking, Black has just the rook as defender on the kingside.
