I was playing a 5d KGS with 2 stones handicap. The beginning was a bit shaky, rapidly progressing into a fight, but we made exchanges and settled the running groups. In the middle game, we made another exchange that allowed me to capture White's corner at the cost of the center. Going into the endgame, I had a very slight lead. And then this happened. In the end, White won by 8.5 points. Looks like I need to brush up on my reading...
