The game below was played in the first round of the third WORLD OPEN RAPID tournament that I have played at the FIDE Online Arena. I played quite well in this game for some time and then I started to mess things up a bit. I won only due to the fact my opponent lost on time. That being said I think that the engine was a bit too optimistic in its evaluation of the position where the game ended. It does not even show a convincing path to victory for White before it thinks that White is completely winning. In my arrogant opinion Black's d-pawn is quite strong and offers nice counterplay. I may look Black's position too optimistically as I was playing with the black pieces in this game but unless there is something other in the position than winning a pawn for White, then I can't really say that White is winning. Maybe further study of the end position is required to give a better evaluation but this will do for now.

If you have been visiting this blog before, you have undoubtedly seen some chances in it. I have today tried different layouts and other things in order to make this more friendly to mobile devices but it might be far from perfect still. I do like the old layout in some ways better but this layout has its own good aspects as well. There might be some changes in the near future as well but the content will always be accessible in one way or another. I have added two mate in ones, one mate in two, one mate in three and one mate in six today. Until tomorrow, my fellow chess enthusiasts!
