A87 Dutch Defence: Leningrad System: 5.Nf3 (1.d4 f5 2.c4 Nf6 3.d5 c6 4.Nc3 g6 5.Nf3 Bg7 6.g3 O-O 7.Bg2 Na6 8.O-O)

This is a game that was played in the round one of the 1800+ 7 Days tournament that is held at Chess.com. This is also the only game I have not lost from the three games I have finished in this tournament. My half a point puts me in seventh place at the moment in this eight player group. My opponent in this game, coronaguy, is currently second in the standings. I was pretty much losing this game until my opponent made a mistake that allowed me to get some counterplay and I saved myself with repeating the position that my opponent could not get away from. My game load keeps easing up a bit every day and I only have 194 games left anymore. At the moment it is still too many games but the quite fast pace of ending games is a positive sight for these old eyes of mine. I have added three mate in twos and two mate in three puzzles today.
