Game I share with you today was played in a thematic team match between Let's Play Benoni and Himgouree's club. This is a small match as it is only played on three boards. I am playing the last game of the match on board 3 for Himgouree's club. Before that game ends we lead the match 1 - 4 as we are the away team. It is also enough points for our team that we have won the match already but officially it has not been declared yet as one game remains. This match started on January 2nd 2015. Now that I look at this game again, it is mysterious to me why I played 21...Nec4?? because I should been able to see the fork on d3. Maybe this was one of those times where I have just made some move because I had to make certain amount of moves in a hurry in order not to lose on time. I have added one mate in one, two mate in twos, one mate in three and one mate in five today.
