B07 Pirc Defence: Miscellaneous Systems (1.e4 d6 2.d4 Nf6 3.Nc3 Nbd7 4.Nf3)

There are some moves in this game that even though they were bad, I didn't make any markings on them, since those moves didn't really change the outcome of the game anymore. There might be in worse case scenario four days when I'm not able to post anything here due to the fact that I'm heading off to a Blitz tournament and I start making my way there tomorrow and come back Monday. There might be also other changes to this blog starting next week, mostly affecting the way I do the analysis. I might also get some training positions in addition to the daily puzzle that already is here in courtesy of GameKnot. Analysis updated February 1st 2015.
