This was wonderful. Thank you. It's rare for us to get any commentaries on old games and it's especially interesting when someone qualified can make comparisons and judgments of the strength of players from hundreds of years ago. It's amazing how much this game had been studied and how much players from this era were already capable of. If you look at old chess games (Western chess) games from only 150 or so years ago are dramatically different and often lacking in many of the concepts that developed in the 20th century.
