Nico Zwirs: An attacking weapon versus the Najdorf
In “An Attacking Weapon versus the Najdorf”, IM Nico Zwirs uses his tried-and-tested system for quickly memorising openings to show how White can actively attack with 6.Bg5 in the Sicilian Najdorf.
In around 86 minutes, he explains typical ideas rather than pure theory: the structure with f4–f5, the exchange of the black-squared bishop and control over d5. Mainlines and sidelines are covered, ideal for advanced players who want to play boldly for a win.

Introduction
Polugaevsky Variation: 6…e6 7.f4 b5
After the Najdorf became popular, White players quickly uncovered two of the sharpest ways to fight back: the English Attack and the aggressive 6.Bg5 line. With 6.Bg5, Black is pushed into playing …e6 instead of …e5, giving White more space to develop – and unleash fireworks! It’s in this opening that the famous Nd5 sacrifices most often appear.
In this brand-new 60 Minutes course, Dutch IM Nico Zwirs shows you how to combine direct attacking play with the powerful light-square strategy. The idea: trade your dark-squared bishop for a knight, push f4–f5, force …e5, and then dominate the juicy d5-square.
This concept makes the lines more clear and easy to remember, giving you the confidence to return 6.Bg5 to your repertoire. With IM Zwirs as your guide, you’ll not only learn theory—you’ll understand the plans behind the moves.
Are you ready to take on the Najdorf with 6.Bg5? Dare to sacrifice, and make the fireworks your own!

In recent years, The London System has exploded in popularity, and it’s easy to see why:
• A rock-solid central structure
• Safe king and stable positions
• Straightforward plans—some surprisingly aggressive
• Minimal theoretical preparation required
No wonder so many club players and even top grandmasters have added it to their repertoire. But this familiarity can be used against the London player.
In this 60-minute course, IM Andrew Martin presents an unorthodox and powerful antidote – an idea first championed by French GM Chabanon and now adopted by several strong grandmasters. Instead of playing passively or falling into well-trodden paths, Black takes the London head-on – aiming to seize the initiative early and steer the game into unfamiliar waters.
This is your chance to surprise London System players and take them out of their comfort zone – right from the opening moves.
