Life In 19x19

Hello,

I somehow stuck on H6 with MFOG, can I ask for review and few tips how to beat this engine?
I attached 3 recent games, maybe there is something obvious which I can't see...

Thanks in advance

I made some comments on your game '03' till about move 70. Generally the game is not bad, however you need some more feeling on which area of the board is important and which groups are strong / getting in danger. As I'm only advanced beginner level treat my comments with care...
