We study openings too much. Way too much.

So why did we make an opening course? Let me explain our reasoning.

We surveyed hundreds of chess players. Those who improved the most studied openings using just 5% of their total chess time. We made this repertoire to get you to 5%.

This repertoire is a complete defense against everything except 1.e4. In just 90 lines.

There is no reason to spend hours and hours memorizing opening lines you will never see. We've all been there. Studying line 400 of a 1000+ line opening repertoire and wondering if we'll ever use it. Wondering if our time isn't spent better somewhere else.

90 Lines

We condensed everything you will see into just 90 lines. The Slav takes time to learn, but you can review it in under an hour.

Just 90 lines? Won't you miss out on essential traps, novelties and gotchyas? Yes and no.

We're going to be recommending offbeat lines. We often recommend strange looking moves that are 4th or 5th most popular. We will get white out of book before we are.

Plans

Since we have fewer lines, we focus heavily on resulting plans.

After each and every line we leave you with a plan. You will never be left in the dark. You will know the best places to put your pieces and how to navigate the middlegame.

Our recommendations are very consistent and you will see many common plans, ideas, and motifs. If you forget a repertoire move in your games-- don't worry. It will be easy to recover. You will know the ideas behind the position.

The best part? This Slav repertoire scores better than most other defenses at the club level. We'll show you exactly why.

Social proof: testimonials

“I’m very impressed with this course. I’ve liked the Triangle system for a long time and I think that this course will enable just about anyone to play it quite well, certainly below perhaps 2200.”
