Score Double Oh Won

For the chess lover in all of us, there is the learner, the problem solver, the one who enjoys to win. I have been playing chess since I was around six and have never really mastered the game. I have yet to play in a tournament, yet I love to solve puzzles and love chess, too. Carleson defends his title in NY tomorrow – keep up with the twelve rounds, here on uschess.org.

Recently, I have attempted to better my game in chess. I am pretty good, however when it comes to winning against people with higher e-l-o ratings, such as 1,300 or above, I am usually short a few combinations. Having just won a match on chess.com with a guest account, I was happy to win against stockfish, the strongest chess engine known of, on level five (there are ten levels). I moved first. For anyone who would like to play this match out with algebraic notation, here is the ‘score analysis’ of the game:
