A50 Queen's Fianchetto Defence (1.d4 Nf6 2.c4 b6) (1.d4 Nf6 c4 c6)

A50 Queen's Fianchetto Defence (1.d4 Nf6 2.c4 b6) (1.d4 Nf6 c4 c6)

Tomorrow I will post a game that features the 200th opening variation that I have covered in this blog! There might be many more still to come but if not, then I will turn my attention back to Chess960. Tomorrow I thought I had found a good way to publish my Chess960 games in this blog but it unfortunately did not work out as there was a restriction on how long the game can be... But now that I type this, a possible solution came to my mind, I will need to try it out tomorrow or perhaps later today if I have time. The game below is one of the 34 losses that I have suffered at Red Hot Pawn which is around 16% of all the rated games I have played there. The average opponent rating in past five years is 1460 so it is pretty low compared to my current rating. I would like have stronger opponents constantly to see how well I could do against them. I do have opponents that are close to or even higher rated than me there currently but there are not that many of them. I guess when I start more tournaments I should join only those that have rating restrictions, to ensure that the people I face are consistently higher rated than my current average opponent. I have added one puzzle to each of the following: mate in three, four, five, seven and twelve.
