{This game from the 5th round of the Dutch Championship was very important for
me. I had had 4 draws in the first rounds of the tournament. I had fallen far
behind my rivals (L'Ami was the leader of the tournament with 3.5 points) and
badly needed a win in this game to be once again in the fight for the title of
the Dutch champion. Luckily there was a rest day before and I had been able to
look at all popular lines and be prepared for everything!  } 1. d4 Nf6 2. c4 e6

analysing this sharp pawn sacrifice which had become very popular recently
with lot of games played in the tournament of all levels incl. the top ones.
This move has also been played against me 9 times, my overall score is +2 in
this system.} 7... exd5 (7... Na6 $5 {is an interesting move. I have tried it
4 times, although with correct play by White Black gets slightly worse and
passive position.}) 8. Nh4 c6 9. cxd5 Nxd5 10. Nf5 Nc7 11. e4 d5 12. Re1 (12.

Bf6 $5 {An interesting move. It seems that Black loses a tempo, after 13.e5
the black bishop has to return back to e7. The strategical idea of this move
is that after the centre has been closed the pressure is released and Black
can finish the development easier. Also White will be under strong presure to
conduct the attack on the Black king - if he fails to mate Black then he might
lose since he is a pawn down. These were exactly the reasons for which I had
chosen this move during my preparation.} (12... dxe4 {and}) (12... d4 {
