History of Opening Master

The original name Opening Master was born in 2004 when the web site was also registered. The founder and creator Alexander Horvath, SIM (1954 - 2013) was a big fan of collecting data since the origin of correspondence chess back in the 80s. I personally remember him writing down all the games in a big red note book, studying the opponents from the older notes and having thousands of books on different openings.

At the beginning he analyzed 3-4-5 pieces board and later on added the 6 pieces (-6 men including the kings).
