Today was quite a good day for making moves, at least I managed to move in a lot more games than I usually am able to. Not sure if all the moves were that great but at least I don't think they were losing moves, so that is good enough for me. The game below is another quite a good draw considering the rating difference in favor of my opponent. I have played two games against this same opponent with a score of 1,5/2, so I have managed a good result against him, will it continue in the two games we have in progress at the moment, is still unclear to me. Oh yes and today I found out that the game I had problems with analysing, would have crashed other peoples programs as well, due to some bug that was in that program. Chessbase support told me that as soon as the next update comes to Deep Fritz 14, it will fix that little problem. I am waiting for that update quite eagerly so that I can share the game with all of you with analysis done to it. I have added more puzzles also today and one more game example in one of my older posts A15 English Opening: Anglo-Indian Defense. Mikenas-Carls Variation.

This paragraph and the ones that follow it have been added November 9th, 2016. The previous sentence only applies to this first game. Both players played quite well until we reached the position below. The last move played in that position was 18.exd5. It was then that my opponent faced an important decision.

CCapivara did not see the danger in the position and played 18...Bxd5. The correct move was 18...Qc5 and it would have kept my opponent in the game. It was then up to me to find the best move, which I did as I played 19.Bxf6. My 19th move was the only move that enabled me to get an advantage. CCapivara's reply to the move was again very important and for the second time in a row my opponent blundered. CCapivara played 19...Qxf6, which could have been a losing move. A better alternative would have been 19...gxf6. I had to play once again the best move in order to take advantage of the blunder. Luckily it was easy enough to see that 20.Nxd5 wins because after 20...Rxd5 I have the move 21.Bh7+!! After my opponent took the bishop, I took the rook with my queen.

I was able to play reasonably well until it came to my 29th move, which I played in the position below. At this time I was rather worried about the possible counterplay that my opponent might get, so I thought that I have to make a passive move like 29.Rd2. My 29th move was a huge mistake. I should have played either 29.h3 or 29.h4 in order to open a square for my king to h2. Had I moved my h-pawn, this game might have had a different result, one more favorable for me...

The move I played was so bad that opponent could have won the game because of it. CCapivara replied correctly with 29...Qb1+, to which I of course answered with 30.Kf2. CCapivara took another wrong path after that and played 30...Nd3+. Had my opponent played 30...Qh1, I would have been quite lost. While 30...Nd3+ allowed me a chance to get a drawish position, but I chose the wrong square with my king. I should have gone to e2, but instead I played 31.Ke3. I did get another chance to fight for the draw when my opponent played 32...Nd1+, but again I messed up. I was a bit lucky as my opponent agreed to a draw after 37...Qf4+. After my 33rd move I should have probably lost the game, so I am happy with the draw.
