Sorry if this sort of thing has been discussed to death before, I'm returning to the site and forum after a number of years away. I've had some mixed success in games around my previous rating, but I always tend to play the same moves. So open with e4 and respond to e4 with d4. Feel out of comfort zone with pretty much anything else including 1. d4 playing as black. To try and go some way to countering that I played 1 ...c6 as black.
Total disaster, I think clearly I needed to play a6 instead of that final Ne7 move, but was that the only place I went horribly wrong? I've been playing around with opening explorers this morning, but not sure whether the line I was going down was totally unsound anyway. Any advice?
