Van't Kruijs Opening Opening Trainer

What this opening is about

This page covers a practical anti-system approach against early e3, c3, d4, and Qb3 structures. The goal is to occupy the center early, finish development, and punish passive move orders.

ChessDrills uses guided repetition so you can practice the move order, review common setups, and stop losing time in the opening. The goal is not to dump theory onto one page. The goal is to make the first phase of the game easier to remember under practical conditions.

If you are building a black repertoire and want a repeatable way to study positions, this opening page gives you a direct route into the trainer while still leaving enough text for search engines and new visitors to understand what the opening does.
