Reacquainted with the game of chess

 My father told me he taught me how to play chess when I was around ten years old, but I don't remember that. I do remember I started to play chess with other people when I was around 15 years old, and I felt confident I was getting better at the game. That, or maybe the people I played against just let me win.

Recently I started playing chess again. My interest in the game was revoked after studying about the field of AI's effort to train computers to play games as well as humans do. While computer programs can be trained to beat some of the best players at certain games, they are still limited in how advanced their playing skills can become because of the immense complexity of games. The number of possible outcomes of the game of chess are enormous. In 1996, the upper bound for reachable chess positions was determined to be 100,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000.

I recently encountered notation used for chess moves in Chess Time, an app I downloaded on my smartphone. The notation involves the letters a through h to denote the columns of squares starting from the player's left and ending at the player's right. The notation he3-g6, for example, means the horse piece moved from the third square in the seventh column of squares from the player's left to the sixth square in the seventh column of squares from the player's left. This notation appeals to me as a convenient way to express chess moves and thus potentially be able to see the game from a higher perspective.
