C01 French: Exchange Variation (1.e4 e6 2.d4 d5 3.exd5 exd5 4.c4 Nf6 5.Nc3 Nc6)

I may be a bit busy this weekend but I will still try to update the blog in the best way possible. As I need to divide my time a bit more maybe than usual, I do this update between rounds of a close chess tournament. Every spare time that I can muster from playing that tournament and moving in my 237 or so correspondence chess games, I use to put more puzzles here and at least one new fully analysed game a day. I have added a bit more puzzles for you to solve in each of the categories starting from mate in ones and ending at a mate in seven exercise. Until next time, my fellow chess enthusiasts.
