Opening Explorer


The Opening Explorer is pulling from ChessDotCom's database of games played by Masters (there are additional settings you can use to explore your games or the games of another person on the site).
The first number (e.g. 1, 5, 38, 44) are the number of games this position has been achieved in that database. The percentages of White/Gray/Black refer to White Winning/Draw/Black Winning.
