Yes I spend most amount off time on move 9 & 18. At 9 it was structural and I had clear goals. At move 18 I was just fighting my mind going blank. I agree with your proposal Qb6.
Thank you very much for your time and sharing your thoughts.
@markkong. Thanks for the reply. 
Hello all,
Here is my fourth OTB-game off the season (I'm black). I had some real difficulties planning (see move 18) So if someone can help me out on that one, I would be very thankfull. Offcourse all other comments are also appreciated
