Yes, its a Blitz game, but still it shows that paying attention and not making automatic moves in the opening is important.
French Advance , with ( in my experience ) a rare 4. dxc5 which just allows me to accelerate my development.
With what could be an automatic 6. Nc3....
I had a quicker mate, but took the material first and then saw that 8.., Qe3 was in fact mate.
Yes, my opponent helped me, but I take a little credit for seeing it !!
