What bothered me was the effect that these games had on my lesson with Yang a half hour later. After the first lesson game was over Yang commented immediately that I had played too quickly. He hadn't told me that in a long time. I knew it was true. I had been sucked into a quick pace with those games earlier, and even though I had taken a half hour to distance myself from them, I continued to play at way too quickly a pace to think through my moves properly for my lesson. This was very disturbing to me.
My lessons are at 11:00 am. I know one thing for sure. I won't be playing any games the morning of my lesson again. I'll do tsumego instead, and play game after.
