C19 French: 3.Nc3 Bb4: Main Line: 7.Nf3 and 7.a4 (1.e4 e6 2.d4 d5 3.Nc3 Bb4 4.e5 Ne7 5.a3 Bxc3+ 6.bxc3 c5 7.Nf3 Qa5 8.Bd2 c4)

One of the rare occasions where there is theory being played in a game of mine longer than two first moves... Even in this example the move order is a bit different than it is in the actual theoretical line but yeah, the same position can be achieved in so many ways. This post comes a bit later during the day because I had to go and try to teach some kids on how to play chess. The first group was maybe a bit too big to handle but the later group was smaller and had better chances of getting something through to them. Luckily I do not have to go there every week but once a month as there are people who rotate through the month.
