This post is only done in order to correct a mistake I did in the past. Sometimes I find a game where I have wrongly categorised the opening. This does not happen all that often, but I have corrected similar mistakes also in the past. The reason why I even look at my older posts is that I have found something in the game I am currently looking at that makes me think that I may have done a mistake in naming the opening variation in the older games. This time I looked a recent game from Red Hot Pawn which was played against someone who I had faced before and because that player had played a similar opening against me, I knew that at least that game is under the wrong post. I also found other games in that same post and there are still some work to be done before I have corrected all that were wrongly placed in my post A45 Indian Game: General. The new opening explorer at the new Chess.com site version has been very helpful tool to me lately. It is much better than the old version of the opening explorer in my opinion. In order to be perfectly clear, I have only done some maintenance today, I have not added new games or puzzles today. The normal posts will continue on Monday. The move order in theory for this opening is 1.d4 Nf6 2.Nf3 e6 3.Bf4.

This was played in the second round of the only 20 minute tournament I have ever played at the FIDE Online Arena and probably the last one too. The only reason I will not play in that tournament again is because there are no official elo games played in it. I do not see any reason to play at the FIDE Online Arena if the games are not official. That is because you can only achieve something by playing official games. After two rounds I had two wins and despite the nature of the games I always play to win. It does not work all the time obviously but the will to win is always there.
