This is an introductory video.
IM Valeri Lilov shares the results of his research and experience to reveal what he believes are the most successful openings for white and for black.
The first question IM Lilov answers is: "What makes an opening successful?"
Of course, the amount of chess theory, the winning percentage, the number of games played with it, and who usually plays it are important factors to determine the success of an opening. But the real thing that makes an opening successful for a player is the knowledge of the right bits; the major ideas, in short, the spirit of the opening. Only with such knowledge at hand, can you earn the key to the castle.
