Riga Open Championship: 4th-6th round

In 4th round my opponent outplayed himself. Before his 27th move position was equal. Then after several bad moves (27.a4?!, 28.Nxd1?, 31.Nd5+? and 32.Nb7?) his position became hopeless.

In the 5th round I played so far my best game in this tournament, against the highest ranked opponent. After opening my position was much better and also later(despite of some mutual inaccuracies and mistakes) I increased my advantage and in 34th move my opponent had to resign.

The 6th round was real nighmare - In opening I had 2 extra pawns and managed to hold them until engdame, which I had to win. I still can`t explain how could I miss such a easy win. Later I had to play carefully to avoid a loss.
