C26 Vienna Game: 2...Nf6, sidelines (1.e4 e5 2.a3 Nf6 3.Nc3)

I may need to rearrange some of my older posts as they are not really up to the standard I would like, so some of them might disappear from the list of openings I have covered and appear under a different one. I think there are three that are maybe not the way I would like them to be. This I found out again today as I was about to update an older post with a new game and then I discovered the opening covered there was not under the post I did about all the openings I have covered and at the same time realized that there was also another opening that for one reason or the other was not included in that list either. That list of openings should be now up to date, considering the current status but I think I will tweak it a bit sometime today as I may delete three of my older posts that are not titled correctly in the opening that is played in them in my arrogant opinion at least. The games featured in them I of course save and repost under the correct opening. I have updated some more puzzles. Mate in ones now features 11 puzzles, mate in two moves has 33 puzzles, mate in threes has 43 puzzles, mate in four moves collection now has 32 puzzles, mate in five has 16 puzzles, mate in six moves has 9, mate in seven has 2 and mate in 11 has currently one puzzle. So currently at the exercises section of the blog are 147 different puzzles and it does increase over time.
