B06 Modern Defence (1.e4 g6 2.d4 Bg7 3.Nf3 d6 4.Nc3 c6 5.Bc4)

B06 Modern Defence (1.e4 g6 2.d4 Bg7 3.Nf3 d6 4.Nc3 c6 5.Bc4)

The week ends with a closer look at a 5 minute chess game. Looking at one of my blitz games seems appropriate, considering that I am going to play roughly 50 5 minute games over the weekend. In the post I am going to do on Monday, I will type more about the tournament I am going to participate in. Or rather have participated in by that point in time. Since most of the weekend is consumed by the tournament, I will not have as much time to prepare for the next week as I would normally have, but as I have done some preparations for next week before the weekend, the content might appear normally in this blog and at my Youtube channel next week.

Now for the game below. This game was part of a hundred game practise match that I played against a friend of mine. The move order played in this game differs a bit from the theoretical move order for this opening variation. The theoretical move order is 1.e4 g6 2.d4 Bg7 3.Nc3 d6 4.Nf3 c6. I usually play a certain line as long as it seems to be working and I am not bored of it. I think I have tried something else on my 5th move other than Bc4, but I felt that it worked against my opponent, so I kept playing it during this match. I mean I am fairly certain that I reached the position after 5.Bc4 a few times during these hundred games. I have not actually gone through all of the games yet, so I can't be 100% sure of the openings played in them. The purpose of the reply 5...h6 is obviously to prevent the move Ng5. The problem with it is that it makes castling kingside somewhat difficult if I can form a battery with my bishop and queen towards h6 before my opponent can castle. A better idea would have been to play 5...Nf6 and follow it up by 6...O-O. The problems that my friend faced in this game started already on move 5. Those problems became even worse when Kojjootti played 12...Nf6 because it would have allowed me to take on e5 with my knight. Kojjootti could not have taken the knight with the queen due to Qd8#. Unfortunately for me, I did not think of that possibility during the game, however, my move 13.Qd6 was reasonably strong too. Things looked very dire for Kojjootti for most of the game, but near the end I gave two chances for my friend to even the game. Both were unintentional bad moves from me. The moves 37.f3 and 38.gxf3 allowed my opponent to take on d5 with the knight in a way that I could not take back because of Be3+ and I would have needed to accept the loss of a rook. Because Kojjootti did not take his chances, I was able to maintain a position that was completely winning for me. I have added mate in two puzzles 718, 719 & 720 and mate in four puzzles 515 & 516 today.
