It turned out that I didn't need the komi. As we approached the second half of the endgame my opponent resigned because it became apparent that my moderate lead could not be overcome as there were only regular end game moves left and no real tricks to be played.
Upon his resignation I immediately became 7k, which was my plan all along.
We had a really good time playing. We agreed to play a slow game and chatted throughout. Adding time, if necessary, was agreed upon by both sides. My opponent played the game on a real board alongside the computer to slow himself down. Since he is very far from a go club he hardly ever gets a chance to play an opponent on his real board.
The whole game had quite a real life club flavor to it, and I will probably use a real board myself next time when I play this opponent to slow myself down as well. Incase anyone is wondering, we did agree that there would be no variations played out on the real board. It is impossible to enforce, I realize, but I trust this person, having known him online for many years.
The real life feeling was enhanced by our review, which we conducted along with another of my online go friends who I started helping back in January, and who has since gone on to become a Yang student. My fellow Yang student showed his superior reading skills by pointing out something I had missed in the game. There was a weakness I was aiming at and I thought that after my opponent had added a couple stones that it no longer worked, but it actually did work due to a ladder. I had tried to read it but was off enough to think it didn't work.
I've saved the game analysis locally to my computer and will go over it again.
