I find his conclusion questionable. He felt that he wasn't aggressive enough in his play, and he failed to adopt a combo/beatdown role to end certain games. However, in doing so, he would have created windows of opportunity for his opponents that could have been exploited, and for all we know, he could have been punished in retrospect for being too aggressive. This could lead him to the opposite conclusion - that he played too aggressively.
It's a tough game to play perfectly, but sometimes we have to be careful in analysing the outcomes when looking back at our reasons for defeat.
Still, a very good article because of both the depth of analysis, and the search for truth (errors that either led to his defeat or at best minimized his chances of winning) rather than chalking up defeats to bad luck.
I think this is right on. I liked the article myself, but like you said Peter, there really is no way in knowing that had he played aggressively would he have created other opportunities for his opponent to take advantage of.
As Travis said, MDG is some hard to play, especially well.
I can't scrutinize my own play as Steve does, but I find it educating when someone does it well, which I think was accomplished here. Anyways, nice report.
