B07 Pirc Defence: Miscellaneous Systems (1.e4 d6 2.d4 Nf6 3.Nc3 g6 4.Bg5 c6 5.f3 Bg7 6.Qd2)

Don't be fooled by my opponent's low rating in this game. When I got the pgn for this game, I noticed that my adversary's rating was a lot lower than I remembered, so I went to look up at his rating profile which contained very interesting info. He had been over 2200 in 2009 but then his rating had gone down very steeply and dropped over 900 points in total until it raised around 400 points again. Well, after learning that he had been a lot higher rated at some point consistently, made me not feel so bad at losing this game as my opponent does seem to have potential for being a really good chess player. My ratings differ a lot too, depending on the time controls and place where the games are played. Maybe the place is not as important as the different players I am facing that makes my rating be really low in some places and rather high in some other places. I have added four mate in two and one mate in four puzzle today and also added something into Chess basics that I had forgotten to add there before. I had left the explanation of a stalemate out of there for some reason. This of course I remembered maybe last night when I was trying to sleep...
