Yes, there are a lot of openings, but I guess the hard way of learning them must be reviewing what went wrong in your past games. This game has nothing to observe, just the fact that black mede worst mistakes. It started with a Karo-Kahn, i read that black needs to play really sharp in order to get a draw and that it only depends of white's mistakes to obtain a win, however, White in here, was me and not a pro.
White's move 17 was a good one, don't you think? Remember to feel free to challenge me , correct me or punish me for the lots of rookie mistakes I still do
