The Zebulon system

The Zébulon system is a chess opening designed to fight the Sicilian Defense with a clear, offensively-minded plan, without requiring a significant time investment studying opening theory. With 1. e4 c5 2. Bishop e2 (White's most common [but not only!] second move in the Zebulon), White opts for a setup far less explored than other closed systems such as 2. Knight c3 followed by Bishop c4 or g3/Bishop g2, and yet, it is solid, dynamic, and resolutely focused on attacking the enemy king.
